Halo: Last One Standing is a short video created in collaboration with Bungie Studios, Neill Blomkamp, WETA Workshop and Origami Digital LLC. It is the last in the trilogy of shorts, continuing where Halo: Combat left off. It was released on September 24, 2007; only twelve hours before the much-anticipated release of Halo 3. In an unusual move, the video was first unveiled on the website of the Discovery Channel, as part of a promotion for a completely unrelated television show titled Last One Standing.
It opens on where Combat Part 1 left off, with the two Marine ODSTs, Bravo-21 (T. Rymann) and Bravo-22 (S. Hartley), in their Warthog making their way to a squad of Marines holding off an advancing column of Jiralhanae. The Spike in Hartley's gut is causing him intense pain and is likely to be fatal without immediate treatment. They drive through an abandoned industrial area toward a damaged satellite dish. When they arrive, they are forced to hold the line, waiting for John-117 to enter range while Bravo-28, a female Corpsman named R. Coney, tries to treat Bravo-22's wounds. A Spike Grenade attaches to a wall near where the Marines are under cover - the Marine retaliates by breaking cover, grabbing the device and hurling it in the air, where it explodes and destroys a strafing Banshee.
A Phantom begins its approach to the ground with a handful of Marines firing upon it. Bravo-21 joins them and flanks a column of Brute Minors and tries to hold them off with a SRS99D-S2 AM Sniper Rifle, actually killing two and pinning a third, until he is ambushed by a Brute Chieftain wielding a Gravity Hammer from his left. He is forced out of his position by it, almost gets tagged by a Spike Grenade and then is chased down by the chieftain. It bats him against a wall then delivers a killing blow, finishing him off.* A Marine mans the M41 LAAG on the Warthog, downing two Brutes before being killed by a Spiker round to the chest. Coney declares him dead moments later, then goes to treat another Marine impaled through the arm with a Spiker round. With the Marine pinned to a wall, the Corpsman has no choice but to use a buzz saw to cut the round in half to free the Marine, causing him great pain.
Finally, a fireball is seen entering the atmosphere. Bravo-22 opens the box that he obtained in the previous video, Halo: Combat, revealing it to be some sort of laser sighting device. He sights the fireball, and "SIERRA 117" appears on the display in the sight. More Brutes are hit as they advance on the Marines.
Their mission accomplished, the wounded squad of Marines and Bravo-22 retreat into a blast door, one Marine, being hit by a Fuel Rod Gun, is blown onto the hood of the Warthog, but recovers and continues fleeing. A Phantom passes overhead, preparing to deploy more Brutes. After the squad gets in the blast door, with Bravo-22 lying against the wall and Coney helping the wounded Marine, another rushes past them to kill the advancing Chieftain with a M41 SSR MAV/AW Rocket Launcher, blowing him to pieces. The blast door closes on them, steeping them in darkness.
In the Warthog, Bravo 22 is screaming in pain, a Spiker round in his abdomen, while Bravo-21 drives and talks on the radio.
Bravo-21: "Command, we're not gonna make it in time!"
Oscar 6 Pilot (COM): "Nearest Medic in Sector 6. Deviate from original course and move to Sector 6. Master Chief's re-entry is minutes away."
Bravo-21: "Okay, got it."
Oscar 6 Pilot (COM): "Proceed with caution. They're under heavy fire."
The Warthog arrives at the scene where three Marines are fighting Brutes. A Brute throws a Spike Grenade at them. Marine #1 provides cover fire for Marine #2 as Marine #2 pulls the Spike Grenades off the wall and throws into the air, taking out a Banshee.
Oscar 6 Pilot (COM): "Sierra 117, search and rescue team is awaiting coordinates."
Bravo-21 jumps out of the Warthog.
Bravo-21: "Medic! Hey, Medic!" (to Bravo-22) "Private...?"
Bravo-22 (COM): "I can do it."
Bravo-21 and Corpsman Coney drag Bravo-22 out of the passenger seat. Bravo-22 screams as the Medic sprays biofoam into his wound.
Oscar 6 Pilot (COM): "You need to get that laser on the Chief."
Bravo-22: "Just get this thing out of me, now! Ugh!"
Bravo-21: "Can you do your job?"
Bravo 21 runs over to the Marines, nearly getting killed by a fuel rod cannon from a Banshee.
Bravo-21: "Hey, what's the situation?"
Scottlee: "We're almost out of ammo, sir, we have to pull back!"
Bravo-21: "Negative, we need to hold them off until Master Chief breaks through. I'll go round and pin 'em down. Make every shot count!"
A Covenant Phantom deploys more Brutes
Bravo 21 runs around the left flank, and shoots two Brutes at a rather close range with his sniper rifle. Suddenly a Brute Chieftain attacks from behind. Bravo 21 tries to run away but the chieftain throws a Spike Grenade at him. Bravo 21 survives the blast but is overtaken by the chieftain. He tries to shoot the chieftain with his side arm, but the chieftain kills him with two blows from its Gravity Hammer.
The other Marines are still fighting. A Banshee comes in for a strafing run, forcing them all to take cover. Just then they look up and see a flaming object falling rapidly from the sky.
Corpsman Coney: "Hold still."
Coney yanks the Spiker round out of Bravo-22; he yelps in pain.
Marine #1: "Go! Go! Go!"
Marine #1 provides cover for Marine #2 who races back and jumps on the LAAG on the back of the 'Hog and begins firing, killing two more Brutes.
Marine #1: "Hit their position!"
Marine #2 is shot in the chest and falls off the Warthog. Coney runs over and briefly checks him.
Corpsman Coney: "He's gone!"
A Brute fires its Spiker, impaling Scottlee's arm to the wall.
Scottlee: "Augh, Medic!"
Coney rushes to Scottlee's position. Scottlee fires his rifle and kills the Brute.
Corpsman Coney: "No, turn away!"
Plasma blasts hit the wall behind them, a few inches from the Marine's arm and hip. Scottlee screams in pain as the Medic cuts the Spike round.
Bravo-22 pulls out laser designator and points it at the object falling from the sky.
Bravo-22: "Target... acquired."
The monitor on the designator begins beeping as it tracks the object which has been now been identified: SIERRA 117.
Oscar 6 Pilot (COM): "That's it; we got him. Recovery team has his coordinates, touching down soon. Fall Back. Fall Back."
Marine #1 turns and runs towards the bunker. A fuel rod cannon blast lands near Marine #1 and he is thrown onto the Warthog, but recovers and runs off while Coney is buzz sawing the Spiker round. A Phantom flies overhead. Coney finishes cutting off the Spiker round in Marine #2. All of them run inside. Marine #1 pauses at the door, lifts and aims a M41 SSR MAV/AW and blows the charging Brute Chieftain to pieces. Doors slam shut.

- The battle rifles used by the marines and ODSTs feature a fully automatic mode of fire. It is unknown if this is an error or a different version of the rifle. Additionally, there are side attachments near the barrel of the rifle and the weapon's scope differs from the model used in Halo 3.
- It would seem that both Combat Part I and Combat Part II are direct prologues to Halo 3, as it explains how Johnson and his unit were able to find John-117 mere minutes after his crash landing on Earth. However, his landing in Halo 3 takes place at night, while Combat Part Two takes place during the day. If he had passed into a different time zone this could be possible, but if so, he surely would have fallen more than "two kilometers" as one of the Marines estimates.
- This video is called "Halo: Last One Standing" with its title really being Halo: Combat Part 2. This confusion is set up by the TV ad that played before and after the video.
- After Bravo-21 is killed, when the Banshee's Fuel Rod Cannon projectile hits, there is a sound that resembles the "Wilhelm Scream", which is heard again in the intro cinematic of Halo Wars.
- The spike grenades have a timer far longer than is seen in Halo 3, with a marine able to emerge from cover, pull the grenade out of a wall, and still have time to throw it at a passing Banshee. These grenades also explode rather than merely sending spikes in a specific direction, though part of this could be due to the exploding Banshee.
