Breach the barrier. Stop Truth.
The Covenant is the eighth campaign level of Halo 3. The level takes place on The Ark. In this level, the player must stop Prophet of Truth from firing the rings. Before reaching Truth, the UNSC and Covenant Separatist forces must deactivate three towers powering the defensive barrier protecting the Prophet's citadel and face off against a massive vehicular Covenant force, including two Scarabs at one time. Finally, united by the common purpose of stopping the rings, the Gravemind offers an alliance with Master Chief Spartan 117 and the Arbiter Thel 'Vadam, only to betray them once Truth is dead, while Cortana's solution to the Flood is finally revealed.
Upon completing it on the Normal, Heroic, or Legendary difficulties, the player will earn the Last Stand achievement and 40 Gamerpoints. Earning over 50,000 points in the campaign meta-game on this level will give the player the Vanguard achievement and 10 Gamerpoints. It is the longest level in Halo 3. It is the last level in which you fight the Covenant (excluding the Easter Egg Grunt on the final level). It is also one of only four levels that is cut into three rally points, rather than two—the others are the previous missions, The Ark, Sierra 117, and Crow's Nest. This level is significant as it is the Covenant's last stand. After the Covenant have been defeated, there is only one last threat the UNSC have to deal with: the Flood. It is also the first level in which you can use the Spartan Laser. The IWHBYD Skull is found on this level, as well as the Thunderstorm Skull.

Three teams. Three towers.
Five Pelicans fly in. They are followed by two Separatist Phantoms. Behind them is the Sangheili Assault Carrier Shadow of Intent. The view changes to a large energy barrier surrounded by Covenant Loyalists
- Commander Miranda Keyes (COM): "We hit these three generators, and the barrier will fall?"
- 343 Guilty Spark (COM): "A small section, yes."
A Grunt spots the flight formation as it approaches the mainland, jumps, and cowers.
- Commander Keyes (COM): "Good enough. Johnson, drop the Chief at the first generator, then head to the third. The Elites will punch right down the middle."
- Sergeant Johnson (COM): "Roger that."
Gunfire hits one of the engines of the following Pelican, forcing it to collide into Hocus' Pelican, tossing the Warthog it carried out onto the ground. The second Pelican swerves out of control.
- Damaged Pelican Pilot (COM): "Mayday! I can't control her!"
The Pelican drops out of sight, followed by the sound of a crash and a muffled explosion.
- Hocus (COM): "Pelican down! Pelican down!"
- ODST Sergeant (Stacker) (COM): "Brace yourselves; we're going in a little hot!"
- ODST Sergeant (Stacker): "Pile out! Go go go! Alright, up the beach! Take out that Wraith!"
- Hocus (COM): "Commander, this is Kilo 23. Lost my Wingman and our only Hog. Over."
- Commander Keyes (COM): "Roger that, Hocus. Get out of there!"
The Master Chief and his Squad secure the beach, and destroy the Anti-Air Wraith
- ODST (COM): "Beachhead secure, Commander. Hostile Anti-Air has been neutralized."
- Commander Keyes (COM): "Hold position. I'm on my way. Shipmaster, begin diversionary bombardment."
- Shipmaster Rtas 'Vadum (COM): "I will beat the Prophet's shield like a drum. By the time the barrier falls, he will beg for mercy."
A Pelican drops off a Mongoose and Warthog for the Chief and his Squad. If the existing squad have all died, replacements will also be dropped.
- Commander Keyes (COM): "Spark believes Truth can activate the rings at anytime. If he does, Earth... every being in the Galaxy... Halo will kill them all."
They mount up and head off for the first tower.
- Commander Keyes (COM): "Get to the first tower. Shut it down."
As the Chief drives up the hill towards the 1st generator, he sees the Separatists' Phantoms battling with the other Loyalists' Phantoms on tower 2.
- Sergeant Johnson (COM): "Ma'am, we're on the ground. Third Tower in sight."
- Commander Keyes (COM): "Good. The Arbiter and the Elites have touched down in number 2."
(Co-op Change) Commander Keyes (COM): "Good. The Elites have touched down in number 2."
- ODST: "Objective in sight! Watch for heavy armor!"
- Commander Keyes (COM): "Chief. You've got to offline that tower."
Keyes' Pelican drops off weapons.
- Commander Keyes (COM): "Get inside that tower. Take it down!"
- ODST: "Perimeter secure. Get inside that tower! Stick together! Check your corners!"
Master Chief gets inside and secures the bottom floor. The ODST and/or Marines hold while the Chief secures the top floor and deactivates the tower.
- ODST: "Go on, sir. Tower controls should be up top!"
- Commander Keyes (COM): "Chief, find the tower controls, and shut it down!"
The Master Chief deactivates Tower 1.
- Commander Keyes (COM): "Good work, Chief! That's one. The Arbiter should be just about to..."
-(Co-op change) Commander Keyes (COM): "Good work, Chief! That's one. The Elites should be just about to..."
Tower 2 shuts down.
- Commander Keyes (COM): "...that's two! It's all up to Johnson's team now."
Chief and Commander Keyes watch Tower 3 for a moment. It remains active.
- Commander Keyes (COM): "Get back outside, Chief. Wait for transport."
- Commander Keyes (COM): "Johnson, come in. Over."
- Sergeant Johnson (COM): "Brute reinforcements, ma'am (static)! We're pinned down!"
- Commander Keyes (COM): "I'm on my way!"
- Sergeant Johnson (COM): "Negative! Fire's too heavy! (to his squad) Everyone fall back! Now! (static and cut-off)"
- Commander Keyes (COM): "Sergeant Major!"
- Commander Keyes (COM): "Johnson! Can you hear me?! (No response) Chief, you need to link up with the Arbiter and proceed directly to the Third Tower. Make your way back to the beach."
-(Co-op change) Commander Keyes (COM): "Chief, you need to link up with the Elites and proceed directly to the Third Tower. Make your way back to the beach."
The Chief hurries back to the elevator, and heads back down. After clearing another of group of Jackals and Grunts attacking the Marines holding the lower floor, the Chief and his squad get back outside to their vehicles, or meet up with transport if they have no vehicles left.
- Marine Driver: "Get in, sir. We gotta get back to the beach."
The Chief and the Marines head back to the beach.
If You Want It Done Right...Edit
Close air support.
- Hocus (COM): "Sir, I've got a flock of birds that need an escort. Take a Hornet; get those Pelicans safely to the Third Tower."
The Chief and his accompanying soldiers meet up with the Hornets and other Marines who held the beach. The Chief and a pair of Marine wingmen get in a Hornet, and the other Hornets assist to clear the airspace of the Second Tower, the Marines aided by a pair of cloaked Separatist Phantoms. Though fighting a large number of Banshees with assistance from a distant Phantom and an Anti-Air Wraith on a nearby island, the Chief and his allies overcome the Loyalist defences.
If the Chief tries to land on the Second Tower (where the fifth Terminal and the Thunderstorm Skull is located):
- Thel 'Vadam (Elite in Co-op) (COM): "Second Tower is clear, Spartan, no need to land. Let us hasten to the Third Tower."
The Chief and company proceed to the Third Tower. Upon reaching its airspace, they are met with heavy resistance, both in the air and on the ground, consisting of at least a dozen Banshees, a Phantom, a few Shade Turrets, a pair of Anti-Air Wraiths, and a handful of Brutes, Jackals and Grunts in the areas behind the Shades.
- Pelican Pilot (COM): "Objective in sight, Commander... No sign of Johnson or his team."
- Commander Keyes (COM): "Understood. Chief, clear an LZ, then get inside the tower."
After the UNSC airborne forces take out the Wraiths and Phantom, the Separatist Phantoms decloak and drop off Thel 'Vadam and his group of Elites and assault the infantry at the tower's entrance. The Chief assists the Elites, scouring the outside of remaining armour and infantry. The Chief lands the Hornet and joins the Elites on the ground. The Marines from Pelicans and Hornets follow up, and secure the perimeter around the entrance to the Third Tower, where 'Vadam and the Elites join the Chief to assault the inside of the tower. They push on inside the tower, encountering two small swarm of Drones, a pair of Hunters, and a large pack of Brutes with their Grunt and Jackal subordinates. The Chief, 'Vadam and their allies overcome this defense and secure both the bottom floor and the elevator (where the sixth Terminal is located).
- Thel 'Vadam: "Darken this tower and the barrier will fall. Go, Spartan! We have no time to waste."
'Vadam and the remaining Elites hold the room while the Master Chief heads up. The Chief secures the top floor, after encountering a War Chieftain wielding a Plasma Cannon, assisted by Cloaked Brute Stalkers.
- Commander Keyes (COM): "Hit the switch, Chief, and the barrier will fall!"
The Chief deactivates the Third Tower.
The barrier falls. The Shadow of Intent advances on the Citadel.
- Rtas 'Vadum (COM): "Now, Prophet...your end has come."
A Slipspace rupture suddenly appears. High Charity emerges from it, and plummets down towards the Ark.
- Rtas 'Vadum (COM): "High Charity... By the gods. Brace for impact!"
The structure flies far over the Citadel and the Separatist Carrier. Debris from High Charity strikes right through the Shadow of Intent's hull. A Flood dispersal pod then breaks apart in midair. Part of the pod crashes right through the window right above the Chief. It stops as it hits the elevator window, glowing eerily. The Chief raises his Assault Rifle and prepares to engage the Flood.
A small group of Human Flood Combat Forms emerge from the rubble, followed by Infection Forms that quickly rush to assimilate the fallen Brutes. The Chief quickly eliminates these few hostiles and goes down the elevator.
- Commander Keyes (COM): "Shipmaster, what's your status?"
- Rtas 'Vadum (COM): "Significant damage! Weapon systems disabled!"
- Commander Keyes (COM): "Move to a safe distance, stay away from the Flood."
- Rtas 'Vadum (COM): "Why would the Parasite come here?!"
- 343 Guilty Spark (COM):(alarmed) "The Ark is out of range of all the active installations! Priority: We must contain this outbreak, before-"
- Commander Keyes (COM): "No. First, we stop Truth. Then we deal with the Flood."
The Chief links up with the Elites and the Arbiter, who are under attack by Flood Combat Forms, including assimilated Elites of their company. After eliminating all Flood forces in the tower, they get outside to find Flood Combat and Carrier forms right outside the door. After dealing with this surprise attack, the Chief and the Elites find the Marines, assisted by some Elites, a landed Separatist Phantom with an Elite using the Plasma Turret, and 343 Guilty Spark; engaged in combat with the Flood, and assist in overthrowing them. 'Vadam proceeds to come aboard the landed Phantom.
- 343 Guilty Spark: "Quickly, I must see the point of impact; assess the damage done to the Ark."
- Thel 'Vadam: "To the top of these hills, Oracle, no higher. We cannot risk your capture by the Flood."
'Vadam takes 343 Guilty Spark with him. A Pelican drop a Gauss Warthog, a Mongoose, and a Scorpion Tank for the assault on the Citadel, along with a few Marines. The Chief, Marines, and what remains of the squad of Elites mount up and prepare for what could be their final battle with the Covenant.
- Commander Keyes (COM): "Shipmaster's Carrier is out of commission, Chief. I need you to take down Truth. The Flood's just going to put pressure on him; accelerate his plans. Punch through the cliffs! Get inside that Citadel!"
Storm the Citadel.
The Assault Team gets through the snowy cliffs, where they encounter a few small Covenant emplacements of a Deployable Tower and Choppers guarded by a pack of Brutes. The Chief and his group easily destroy this outpost and soon find themselves on the cliffs around the Citadel.
- Pelican Pilot (COM): "Citadel in sight! Brutes are mobilizing everything they've got."
The Assault Team clears the cliff, facing Ghosts, Shade Turrets, Banshees, Deployable Towers, Prowlers, and many Brutes armed with heavy weapons. Once they are dealt with, a lone Wraith near a Deployable Tower is the only thing standing in their path, and once taken out they meet with Hornet Gunships near the route down into the clearing, with Warthogs and Mongeese fighting Ghosts, Choppers and Prowlers in the valley that leads to the Citadel, along with Pelicans and Hornets fighting Banshees in the skies above.
- Marine Sergeant (Stacker) (COM): "Hornets, inbound!"
Depending on choice, the Master Chief takes a Hornet and makes his way to the Citadel, when a pair of Scarabs suddenly drop down from above him and his allies.
- Pelican Pilot (COM) "I count two Scarabs! Repeat: two Scarabs!"
With the choice Chief chooses, the Assault Team backs him up, and an epic battle commences: The Scorpion Tank gives long range covering fire from the cliffs while the Warthogs and a Mongoose move about under the Scarabs to assist Chief in taking their "legs" down with Rocket Launchers and Gauss Cannons whilst dealing with the Brutes and Grunts manning the ground vehicles, and the Hornets engage the Scarabs and Banshees from the air. But more Ghosts, Banshees and another Prowler help to defend the Scarabs.
Eventually, the Chief takes out the first Scarab.
- Commander Keyes (COM): "First Scarab's down! All units, concentrate your fire on number two."
Though additional reinforcements come to defend the Scarabs, the Chief eventually obliterates the second Scarab.
- Commander Keyes (COM): "Both Scarabs down, well done."
If any notable Covenant resistance is left:
- Commander Keyes (COM): "Marines! Kill the stragglers!"
A Separatist Phantom arrives at the platform leading to the entrance of the Citadel, dropping off Thel 'Vadam, Energy Sword drawn, and 343 Guilty Spark.
If the Chief isn't there when 'Vadam lands:
- Thel 'Vadam (COM): "Spartan, come to me. This platform hides a path!"
- Commander Keyes (COM): "Spark has found a way into the Citadel. He's waiting for you on the platform, Chief. Go!"
The Chief lands and meets 'Vadam and 343 Guilty Spark at the top of the Platform.
- Thel 'Vadam: "The Flood scales the Citadel's far wall. Activate this bridge, Oracle! (turning to the Chief) The Prophet will die by my hands, not theirs."
The Forerunner Bridge to the Citadel activate and a small portion of the doorway to it opens up to allow entry. Both the Chief and the Arbiter run across the Bridge towards the doorway.
- 343 Guilty Spark: "Calamity! If only we had more time!"
The Chief and 'Vadam enter alone. The door they entered through fully closes and bolts up. The entrance is a large hallway with screens mounted along the walls.
- Cortana (Cortana Moment): "It asked, and I answered. (turns bitter) For a moment of safety, I loosed damnation upon the stars."
- Prophet of Truth (Voice): "My faithful...stand firm..."
Viewscreens around the Chief light up. The Prophet of Truth is seen making another speech. The Chief and 'Vadam hurry to find a way up.
- Prophet of Truth (Video COM): "Though our enemies crowd around us, we tread the blessed path. In a moment, I will light the rings! And all who believe...shall be saved!"
Master Chief and 'Vadam discover an elevator, with a screen in front of it, showing Johnson behind Truth, held aloft by a Brute. Johnson punches the Brute in the face, to no effect.
- Commander Keyes (COM): "Chief, how close are you?"
They look up. The height is phenomenal.
- Master Chief: "Not close enough."
The view changes to the Control Center. Johnson is being thrown at the floor.
- Sergeant Johnson: "That the best you got?"
A Brute Chieftain gives him an amused huff, then picks him up around the neck and begins to strangle him.
- Sergeant Johnson: "Oh, come on. Impress me."
Truth turns around and sees what is happening.
- Prophet of Truth: "Stop, you imbecile! He wants you to kill him! (turns back to The Ark's console, and speaks quietly) I'd prefer that you did not."
The Chieftain slams Johnson's head into the solid holographic console.
- Sergeant Johnson: "What's the matter, big shot? Can't start your own party?"
- Prophet of Truth: "I admit, I need your help." (a Pelican appears on screen behind them, unnoticed and rapidly approaching the main window) "But that secret dies with all the rest."
The Pelican breaks through the window and crashes onto the ledge next to them, crushing a Brute, sending his Spiker flying. Truth is thrown off-screen, landing near the Spiker.
- Commander Keyes: "Johnson! (ejects a shell from her shotgun) Sound off!"
- Sergeant Johnson: "(coughing) Get out of here!"
- Commander Keyes: "Not without you!"
More Brutes surround Miranda and Johnson. Miranda fires away at the Brutes with her Shotgun. Their armor spark from the shots, but the short-range weapon does not do severe damage to them, and they remain on their feet.
- Prophet of Truth: "You delay the inevitable. One of you will light the rings."
Miranda Keyes draws a Pistol and aims her weapons both ways.
- Prophet of Truth: "You cannot hope to kill them all!"
Keyes pauses and lowers her weapons. She looks at her pistol.
- Commander Keyes: "You're right..."
She reluctantly aims the pistol at Johnson.
- Sergeant Johnson: "Do it. Me...then you..."
Keyes hesitates, lowering her pistol slightly with sadness on her face.
- Sergeant Johnson: "Now!"
Keyes straightens up and aims. Five Spiker shots are heard.
- Commander Keyes: (gasp)
Keyes drops her weapons. Johnson starts to run to her aid.
- Sergeant Johnson: "No!"
A Brute Captain restrains Johnson, who still struggles, horrified. Miranda Keyes falls to her knees, collapses, and dies, with five glowing spikes in her back. Truth slowly steps on screen, gingerly holding a Spiker in hand.
- Prophet of Truth: "Your forefathers wisely set aside their compassion..."
He looks down at Miranda and drops the Spiker, and shakes a fist to emphasize his speech.
- Prophet of Truth: "...steeled themselves for what needed to be done."
Truth walks up to Johnson.
- Prophet of Truth: "I see now why they left you behind."
Sergeant Johnson is brought up to the control panel.
- Prophet of Truth: "You were weak...and gods must be strong."
He forces Johnson's hand down on the panel with a smug look. Johnson, overcome with grief and shock from Miranda's death, doesn't resist. Instantly the Control Terminal begins to change and heighten. Truth raises his arms in triumph. Six out of Seven Holographic Halo Rings light up one by one (Installation 04 had been destroyed, so its ring does not light up). At the end of the corridor, the Chief and Thel 'Vadam emerge from the lift. Two Flood Tank Forms drop from above. The Master Chief draws his Assault rifle and aims, and 'Vadam activates his Energy Sword.
- Gravemind (through the Tank Forms): "Do not shoot, but listen! Let me lead you safely to our foe. Only you can halt what he has set in motion."
They lower their weapons cautiously. Several Infection Forms scurry between their feet towards their common enemy, the Prophet of Truth. The Master Chief and 'Vadam look at each other, obviously not trusting the Flood, but knowing they have no other choice.
The Master Chief, The Arbiter, and the Flood begin their assault on the remaining Covenant infantry, the Flood charging and assimilating Brute after Brute, while 'Vadam, Energy Sword to bear, makes a mad charge on the Loyalists. After encountering heavy resistance whilst crossing a bridge guarded by Brutes, Grunts and Jackals armed with heavy weapons, they reach a room with a hologram of Truth' placed on either side.
- Prophet of Truth (Hologram): "How could I have known the Parasite would follow?! Undoubtedly this is the Heretics' doing! A final, bitter curse. Clear evidence of treachery long hidden!"
At the second bridge, the Covenant forces make their final resistance. The Master Chief and the Arbiter eventually defeat the last of Truth's followers - including a Brute Chieftain wielding a Gravity Hammer, and his Bodyguards.
At the second room, Truth's holograms broadcast a final message.
- Prophet of Truth (Hologram): "So far are we along the path, that I must strain to hear the clumsy patter of their pursuit. Know this my brothers, they may foul the way with their charred and broken bones, but they will not stop the Journey."
The resistance on the third bridge has already been routed by the Flood. A light bridge is all that remains to reach Truth.
Master Chief and The Arbiter cross the light bridge, and come across Johnson, who is resting the dead Miranda Keyes on his lap by her head next to the Pelican. The pair stare into Miranda's empty eyes, until Johnson closes them gently.
- Sergeant Johnson: "Stop the rings. Save the rest."
The Chief continues to stare at Miranda, shoulders slumped, obviously disheartened, while 'Vadam approaches the crawling form of Truth, his Energy Sword turned off but at the ready. He grabs Truth by his robes and points his currently harmless sword in his face.
- Prophet of Truth: (Weakly) "Can you see, Arbiter? The moment of salvation is at hand."
- Thel 'Vadam: (grabbing Truth by the throat) "It will not last!"
- Prophet of Truth: "Your kind... never believed in the promise of the sacred rings."
- Gravemind (Speaking through Truth): "Lies for the weak. Beacons for the deluded."
At this moment, 'Vadam draws his Energy Sword back and activates it, ready to kill his former leader.
- Thel 'Vadam: "I will have my revenge. On a Prophet, not a plague!"
- Prophet of Truth: "My feet tread the path. I shall become a god!"
Tentacles begin to sprout on Truth as the Flood infection progresses.
- Gravemind (Speaking through Truth): "You will be food - nothing more."
The Chief approaches the Ark's Control Panel, ready to deactivate it.
- Truth: "No!"
The Chief deactivates the Ark. The six holographic Halo rings dim. A Flood body begins to stir.
- Prophet of Truth: (being held aloft by 'Vadam) "I...am...Truth! The voice of the Covenant!"
'Vadam turns Truth away from him and grabs his neck viciously. Truth's crown falls off as he pitifully gasps for air, trying to grab 'Vadam's hands.
- Thel 'Vadam: "And so, you must be silenced."
(With IWHBYD skull on.)
- Thel 'Vadam: "Asshole, you must be silenced"
'Vadam stabs his sword through Truth's back. It goes clean through him; the two points of the Energy Sword poke through his chest.
- Truth: "Ahhhhhh!
Truth writhes and screams in pain. Flood spores shoot out of his mouth and the infection lets out a pitiful squeal. The last of the High Prophets is dead.
'Vadam lets Truth's corpse fall to the floor. 'Vadam lets out a roar of triumph and deactivates his sword. The Chief looks at him and nods, acknowledging him for ending the life of the Prophet who declared war on humanity; they then turn to see Johnson carrying Miranda's body into the Pelican. There is a moment of silence as they realize their victory has not been without loss.
Suddenly, the ground begins to tremble, and massive tentacles rise up all around them. Chief wields his Assault Rifle and 'Vadam reactivates his sword. They both stare up at the tentacles, which are now reaching high above them. The Gravemind laughs manically.
Johnson leaps into the Pelican cockpit and starts to take off. The Chief climbs onto the Control Panel of the Ark and jumps onto the Pelican's landing gear. Chief grabs onto Thel's hand. Just before the Pelican is out of the hole in the Control Room window that Miranda made, both are knocked off by the tentacles, sending the Pelican spiraling out of control. On the ring, the tentacles swerve around them and multiple Flood forms appear.
- Gravemind: "Now the gate has been unlatched, headstones pushed aside...corpses shift and offer room, a fate you must abide!"
'Vadam holds his sword at the ready, and the Chief takes aim with his Assault Rifle. They come back to back.
- Thel 'Vadam: (almost exasperated) "We trade one villain for another."
The tentacles retreat and Combat Forms come up from the control panel.
- Sergeant Johnson (COM): "I can barely keep hold of her, Chief! No way I could pick you up! Head back to the lift... find a way down!"
Both heroes fight their way through hordes of Flood, which have betrayed them now that the Halo rings have been deactivated. Fortunately, the Sentinels are also here and are fighting the Flood.
- Cortana (Cortana Moment): "I'm a thief...but I keep what I steal."
Master Chief and Thel 'Vadam make it back. The lift is not working, so they jump down a shaft at the back of the room.
The Chief lands at the bottom of the shaft, landing in a room not unlike the entrances to the three Shield Towers. He looks beside him as the Arbiter comes down, and then stands up. A flickering, spooky image of Cortana appears in the hallway, running. She starts to turn the corner and disappears, after a split second. The Chief casually walks around the corner as though amused by Cortana's antics, but 'Vadam is confused.
- Thel 'Vadam: "What do you see?"
With 'Vadam trailing far behind, the Chief looks around the corner. He sees a control panel. Cortana appears a second time, again for only a second, walking loftily (and spookily) towards it. She stops at the panel and disappears. The Master Chief goes to the panel and activates it.
A view screen slides open, the Chief and 'Vadam step out onto a balcony to watch as a massive structure rises up out of thick fog. It's a Halo Ring, incomplete, rising from inside the Ark's Core. Cortana's plan is becoming clear.
'Vadam turns and looks at the Chief.
- Thel 'Vadam: "A replacement. For the ring you destroyed."
- Master Chief: (to a blue glow behind him) "When did you know?"
Spark hovers up from behind the Chief and 'Vadam and comes up to the Chief.
- 343 Guilty Spark: "Just now - but...I had my hopes. What will you do?"
- Master Chief: "Light it."
- 343 Guilty Spark: "...Then we are agreed! A tactical pulse will completely eradicate the local infestation! I will personally oversee the final preparations."
He flies enthusiastically around the Chief and 'Vadam, who look at each other, and then flies off toward his new Halo, now talking to himself.
- 343 Guilty Spark: "Though it will take time to fabricate an activation index, I will see to the letter that..." (he flies too far away)
- Thel 'Vadam: "How will you light it?"
They both turn to look at High Charity, knowing that Cortana still has the Halo Index required to activate the new Installation 04.
Fade to black.
At the start of "If you want it done right...", fly through the level as normal, and when you come to the construct where Sergeant Johnson's team lost contact, land on the right side. Go up against the back wall and look for a covenant weapon case. It holds a fuel rod gun with 15 extra shots.
- The spartan laser is seemingly the only weapon you can use to kill 343 Guilty Spark (as demonstrated in the final level, "Halo"). However, if you carry the spartan laser given to you from the beginning of this level right until you encounter Spark (after destroying the two scarabs), he will be immune to any shots you fire at him and will only curse you. No physical damage is done unlike in the final level of the game where it takes three shots to kill him.
- The beginning of the level pays homage to the beginning of The Silent Cartographer. Both levels start of with cutscenes of a group of Pelicans flying in towards a beach. You then get to see from Master Chiefs perspective as you approach the drop. Finally, you are dropped of on the beach and have to engage a large group of enemies.
- Main article: Glitches
- If the Brute Chieftan directly before the cutscene where the Arbiter kills Truth is infected by the flood, his Gravity Hammer will disappear when the infection is complete.
- If you start at Rally Point Alpha, and head back to the first tower, the elevator controls will be separated from the platform, and if you go up, you will be stuck, because the controls remain at the bottom of the lift. If you do not go up the lift, the Hornets you need to continue the level with will disappear. If you destroy the two Hornets the Marine Pilots offer, the third Hornet will fly down to you. You can get him out and drive this particular Hornet to the first tower and reach incredible heights. If you go near the first tower entrance, the Hornet will disappear.
- If you get to the texture fault where the hidden Marine is, you can see the other player's screen. If you drive into it, you will be erased out of the map.
- It is possible to get into the second tower that the Arbiter disabled using the Time Travel Glitch. The tower's interior is just an empty space with nothing inside, not even floors or walls as you can see in this here.
- Occasionally, while a corpse is being infected by the flood, without the first Infection form dying, another Infection Form may enter it. Despite this, only one Infection Form will be present in the combat form. The other infection form will be attempting to dig into the corpse.
- The Disappearing on The Covenant glitch can be performed on this level.
- The Two Arbiters Glitch can be performed on this level.
- The Secret Marine Glitch can be performed on this level.
- The Infected Brute Chieftain Glitch may be seen on this level.
- The Drive an AA Wraith Glitch can be preformed on this level.
- Occasionally, when a Banshee pilot dies, or when you board one, the Brute will be holding a human Battle Rifle.
- If you destroy a Scarab's power core right after it lands, you and everyone else on the Scarab will be thrown across the map. It can also be performed if you ride in a Hornet and jump off when you are over the Scarab. Then you must bypass the enemies and melee the power core.
- You can jump over the chasm where you are supposed to activate a light bridge and reach Truth by using a Gravity Hammer and a Plasma Grenade. By grenade jumping backwards and using the Hammer at the peak of your jump, you can be propelled across the chasm, but if you land safely, the bridge will strangely activate on its own, and the cutscene will play.
- At the part where the Flood offer to help you in stopping the firing of the rings, if you have subtitles on, when the Gravemind says "halt", the subtitles say "stop".
- On Co-op, if you glitch into the Citadel, the Flood will be your enemy.
- If a weapon is dropped on either side of the two elevators the player will be unable to pick it up again, however ammunition can be retrieved from the weapon. However, if you shoot the weapon, you can retrieve it by quickly holding the RB button when you see the prompt.
- Using the time travel glitch, you can have a special glitch happen here. As a hint of what will happen is that one scene will be interlaced with another one and the music will blend.
- It is possible to "drive" a Scarab in this level. First kill one then land on the other. Kill all enemies then stand on the top. It will walk towards the direction you are aiming at because it's AI is scripted to follow you.
- You can actually ride in certain Pelicans in this level by bringing your Hornet right up to the back of the Pelican, getting out, and holding "RB". If you did it right you will ride in the Pelican.
- At Rally Point Alpha, on the island where the Phantom deploys the Anti-air Wraith, you can trick the game into believing that you're stranded on the island. Then the game will spawn a Hornet piloted by a Marine Pilot who will land it on the island and offer it to you. You can have infinite Marine Pilots and an infinite number of Pilot controlled Hornets by exploiting this causing the map to overload.
- When you make the Elites your enemy and you get in a vehicle and allow an Elite to board you, he will be unable to melee you or melee you out.
- If you retain 343 Guilty Spark by destroying the Separatist Phantom that comes to pick up Arbiter and deploy an Auto-turret facing Guilty Spark, the Auto-turret will shoot at him for unknown reasons.
- If Tilt and Cowbell skulls are turned on, and you have kept the Warthog you received at Mission Start, you can drive it into the first tower and onto the elevator and propel yourself to the upper level with a plasma grenade. The Brute Chieftain, his bodyguards, and the two Brutes will not attack you.
- It is possible to progress through the level without destroying the anti-air Wraith. The Pelican will not arrive and no enemies will spawn in the canyon that you would otherwise drive through.
- If start at rally point alpha and land the hornets on top of the pelican, the pelican will start to sink underground
- If you Tea-Bag the Prophet once you kill him, eventually he will fall through the floor.
- Right when the player heads out of the cave to the Citadel, the player will see two Banshees pass by. These two Banshees seem to appear out of nowhere. This can be easily seen on Theater.
- Just before Rally Point Bravo, when you exit the Third Barrier Tower, an Elite Phantom will be waiting. It is possible to jump into it before it leaves. The doors will close, it will start flying away, activate its Active Camouflage, and disappear, making you fall to your death.
- During the Scorpion rampage after Rally Point Bravo, after you pass and destroy the second Deployable Lookout Tower and the ghosts, there is a tunnel with a Fuel Rod in it. If you drive directly over this tunnel in your scorpion, and fall back down to the ground level of the tunnel, your scorpion, you, and your marines (if you have any) will be catapulted across the map.
- In the first cutscene, when the Warthog is knocked from the Pelican carrying John 117 during the beach approach, you can see that it is intact and undamaged when it hits the ground, but when you walk up to it in gameplay, it is destroyed and in pieces, most notably with the wheels missing. Also in the first cutscene, the Warthogs attached to the Pelicans are clearly troop transports, yet when you survey their wreckage during gameplay, the models actually have destroyed LAAGs. Also when you get out of the pelican after the first cutscenes, if you turn around you will see two pelicans dropping off troops instead of one (Hocus' pelican)
- During the first cutscene that takes place in the Citadel, the screens in the "foyer" show Johnson being held by a Brute Minor. Later in that cutscene, however, the Brute inexplicably changes into a Chieftain. It is possible that the Brute Minor had quickly "passed" Johnson to the Chieftain when the Master Chief and Arbiter gaze at the lift's height.
- At the same screen mentioned above, the Prophet of Truth was already out of his gravity throne, as the 2 "spikes" on the throne were missing.
- When the Prophet of Truth is killed by the Arbiter during the cutscene, he loses his crown. However, when the gameplay resumes and Truth is dead on the floor, he is still wearing his crown.
- Near the end of the cutscene in which the Arbiter kills the Prophet of Truth, two Brute Flood Combat Forms are seen climbing over the Ark's controls to attack the Chief and the Arbiter. However, when gameplay resumes, it is two Elite Flood Combat Forms that are standing in front of the Ark's controls.
- When you deactivate the shield in the third tower where Johnson failed to do so, you are attacked by Flood who come crashing through a window. However, when the tower is seen from outside (in the area with the two Scarabs), the glass is intact.
- The Pelican that crashes at the start flies past the wreckage and lands at the waterfall—it doesn't land where its crash site was positioned. Sometimes, its two pilots' bodies can be found in or around the water below the waterfall.
- If you watch the sky when the Scarabs fall down, you see that they fall from nowhere. Entering the Hornet will trigger the Scarabs' appearance, and a Hornet does not allow the player to look up to the point where the Scarabs appear. To see the mistake, you must get in the Hornet and then immediately get out to look up.
- When you are in the zone where the two Scarabs are, you can see a huge air battle over you with Pelicans, Hornets and a lot of Banshees squadrons. But if you look carefully, you can see that the battle is always repeated. You can look at this battle closer with the Theater mode or at the Secret Marine emplacement. If you look at the battle in the Theater mode, you can see that the Pelicans and the Hornets are badly textured, but the Banshees are fully textured with dynamic lighting on it.
- If you look at where the Scarabs land, you'll see that they have marked landing spots.
- After the cutscene where Arbiter has killed Truth, if you hit the dead prophet you'll find that he can disappear through the floor.
- The two Scarabs seem to use thrusters to slow their landing down. If the player pauses (on Theater) when the Scarabs are about to land, they will notice that the Scarabs don't seem to have anything that possess their thrusters.
- Main article: Easter Eggs
- The Thunderstorm and IWHBYD Skulls can be found on this level.
- The Siege of Madrigal song and Microsoft Sam can be heard on this level.
- The lone Marine can be found in this level.
- If the IWHBYD skull is activated Thel 'Vadam will say "asshole, you must be silenced" instead of "and so, you must be silenced" during the execution of Truth.
- When you use the elevator to ascend to the tops of the first and third shield towers, the Marathon symbol can be seen in the middle of the elevator control panels.
- The first chapter of the level is named "Trident". This refers to the three towers and the Citadel. There are three spikes on a trident—a metaphor for the towers. The handle that the spikes lead up is a metaphor for the Citadel.
- In the opening cutscene, there are 7 ally dropships in total: 5 Pelicans and 2 Separatist Phantoms.
- It can also be noted that the '7 Halo Ring' part of this level, the ones which you have to jump through, can be traced back to Halo 3rd Person view mode, which can be seen here, Evolution of Halo, just forward to 6:32.
- At the very end of the level (right after Truth gets killed by the Arbiter), if you turn around and look above the glass that Keyes' Pelican crashed through, there is a prominent Marathon symbol.
- There is a second Spartan Laser near the crashed Pelican at the beginning of the level. It is only there when you are playing on Easy or Normal difficulty.
- Bungie has stated that this is the longest level in the whole Halo Trilogy, partially because it is the Covenant's last stand against Humanity. It is also the only Campaign level where players can use Hornets.
- Hijacking the first Anti-Air Wraith in the level will make progressing up to the first tower a lot easier; you will also be able to bombard the Covenant forces hiding in the hallway just before the tower's entrance. A video of this can be found here: AA Wraith Glitch
- At the point where you reunite with the Arbiter and 343 Guilty Spark after defeating the Scarabs, if there are any surviving Covenant forces nearby, 343 Guilty Spark will attack them with the same energy beam he uses against you in the Control Room later in the game.
- This is the only level in which friendly dropships can be destroyed. The two Separatist Phantoms that appear outside the third tower can be destroyed. Their door-mounted Plasma Cannons can also be blown off from the ground, and are very useful against the Drones inside. However, a well placed frag grenade (after luring the Drones to the left side of the tower) is more reliable.
- At the beginning of the level, Gunnery Sergeant Marcus Stacker is usually leading the ODST squad that joins the Master Chief in battle.
- This is the only level in the Halo Trilogy that involves a battle against two Scarabs at the same time.
- It is possible to get a Mongoose or a Warthog onto the one of the Scarabs in the Scarab fight. Bungie has conveniently placed ramps leading up to both Scarabs as soon as they land. Grab a Mongoose or a Warthog and just line up the Scarab when you jump.
- The platform at the end of the Citadel could be a large Marathon symbol, due to the break in the large platform in the front, and the smaller circle in the center.
- This is the second and last level to have ODSTs fight alongside with you.
- The Legendary symbol, granted for completing this level on Legendary, can be seen in the Campaign selection screen, and is one of the two symbols that is darker than the rest.
- There is a strange voice whispering through the walls of the third tower after you have defeated the Brute Stalkers and Chieftain. If you listen closely to the walls (particularly the wall closest to the activation panel), a faint voice can be heard whispering something inaudible to you. The voice has not yet been identified but the voice does resemble Gravemind's deep empowering voice. Some fans believe that it is foreshadowing the Flood's arrival only seconds later. Though the voice does resemble some sort of backwards song it is still unknown whether this voice is significant or not. However, it has not been confirmed that this strange voice is Gravemind's or just a fan's speculation. To some this voice may be a monitor or even 032 Mendicant Bias himself but to others it may be something more.
- This is the first and only level in the entire series in which the Flood are your allies.
- Upon entering the Citadel (after you defeat the two Scarabs), the Cortana Moment you experience before the cutscene is projected on the holoscreens in mirror image to what is in your visor.
- This is one of the only two levels where the player can achieve Too Close to the Sun, other being The Storm. The easiest part is during the Chapter If You want it Done Right, the player can land on the island where the AA Wraith is, and fire their laser from there.
- The Anti-Air Wraiths, other than the ones on the beach and the island, cannot be boarded. When approached, there is no "Hold RB to board enemy Wraith" message. Even the hijacking glitch doesn't work.
- It is impossible to board the anti-air wraiths that appear in the part where you must fly the hornet.
- When the Scarabs drop down toward the end of the level, each Scarab "warms up". The one on the left does a cat stretch (stretches its neck up while forcing its lower back down), and the one on the right twists its man gun back and forth like it was cracking its neck.
