Scarab is the seventh level of Halo Wars.
After several Plasma-based Rhinos take down the dome, UNSC forces are sent inside to find out what the Covenant were protecting. As a couple of Rhinos patrol the area, they are easily destroyed by the nearby immobile but functional Super Scarab. As the UNSC forces are alerted of this threat, Captain Cutter orders all UNSC units inside the former dome to destroy the Scarab before the Covenant make it mobile. As advised by the A.I. Serina, UNSC forces including Sergeant John Forge take out the Power Nodes linking to the Scarab, and after destroying all of them, they took advantage of the fact that as the Scarab has fewer Power Nodes, it's head will move more slowly. The base that the UNSC had set up was directly in front of the Super Scarab, but was blocked by a wall-like barrier of Forerunner structures. The Scarab attempted to break through the wall, however it didn't have time to succeed. As more Power Nodes were disabled the Scarab's head moved more sluggishly, which gave Forge and the other UNSC troops more time to destroy it. Before the barrier could be destroyed the UNSC forces in the former Covenant-occupied dome had successfully destroyed the Scarab with several types of ground vehicles and a MAC Cannon from the orbiting Spirit of Fire; however, the UNSC suffered significant losses.
- Regret: "Arbiter, you are unusually quiet. What troubles occupy your thoughts?"
- Ripa 'Moramee: "Hierarch, I do not wish to be impudent, but you have charged me with the destruction of humanity-"
- Regret: "A most noble cause, for one with such a troubled past."
- Ripa 'Moramee: "And I am thankful for my task. But sire, you have me skulk in ancient ruins and search empty temples. How does this help me accomplish my goal?"
- Regret: "The war with the Humans will require a great deal many more machines than we can currently muster."
The Arbiter draws his two Energy Swords. The Honor Guards react slightly.
- Ripa 'Moramee: "I will take what we have!"
- Regret: "And leave us defenseless? No. The Ancients will provide for us. This world shall be the birthplace for an invasion fleet beyond imagining. Enough to crush the Humans quickly...and with ease."
- Ripa 'Moramee: "But this world lies dormant, it is just a shell."
- Regret: "Blasphemy! The key will be found with patience."
Regret tries to activate the structure, but the panel flashes with red light.
- Regret: "But perhaps, there is a quicker way. The human female from the ice relic, she has some knowledge in this regard. The new planet the Relic has lead us to has also led her. Capture that human and bring her here!"
- Ripa 'Moramee: "It will be done."
The Arbiter departs.
Fade back into Arcadia, inside the now ruined dome shield.
- Captain Cutter: "You've advanced to where the force field stood, take a look around."
Two Rhinos move past several ruins into the open, but one is destroyed by a green plasma beam. The other faces the attacker before it suffers the same fate.
- Forge: "What was that?"
The beam is revealed to come from an incomplete, yet active oversized Scarab
- Serina: "The Scarab is incomplete, but its head is operational. Its field of fire prevents any chance of retreat or extraction. You'll have to destroy it."
- Forge: "Build up our base and army, and go kill that Scarab."
- Forge: "The Scarab's searchlight beam shows the direction its facing. The temple ruins in this area will provide some cover, but not forever."
- Forge: "Damn it, spotted."
After destroying a power node:
- Serina: "You've destroyed a power node, the Scarab's head is turning a little more slowly."
After destroying a Locust
- Forge: "Destroy those Locusts where ever you find them, they're building killers."
After a second power node is destroyed:
- Serina: "The Scarab's head is moving even slower now, keep it up."
- Captain Cutter: "The Scarab's weapon system is relying on the power nodes in this area, destroy them to reduce the Scarab's combat effectiveness."
If a third node is destroyed:
- Serina: "The head is tracking more slowly."
- Forge: "They've launched a counter-attack on our base!"
When your forces near where the scarab is positioned:
- Forge: "It can't fire in two directions at once, maybe we can use that to our advantage."
When the Scarab's health is halfway:
- Serina: "The Scarab is about half-dead or half-alive, take your pick."
When the Scarab's health is low:
- Serina: "Almost there, the Scarab is nearly destroyed."
- Forge: "If that thing burns through that barrier of ruins and destroys our Command Center, we're dead."
At some point during the battle, on Heroic or Legendary:
- Forge: "The Engineers are repairing the Scarab! Take them out!"
After intense and heavy fighting, the Scarab is finally destroyed.
- Serina: "No problem, I told you we'd make it."
The Scarab explodes in a tremendous display of fireworks with fiery debris raining everywhere.
Captain Cutter: "The Scarab is destroyed. Victory is ours today."
- The Scarab is not a normal Scarab because of its appearance and functions. When you view its name in-game, instead of saying Scarab it says "Super Scarab." The sheer size of it, coupled with the immense amount of damage it can take, obviously sets it apart from the usual Covenant Scarab. Although it is incomplete, this "Super Scarab" bears a strong resemblance to the Halo 2 Scarab variant.
- A tip which may help inexperienced commanders here is to divide and conquer. The basic strategy involves mass-producing Wolverine units and keeping them under cover, then have other forces attack the power nodes to cut off the Scarab's head movement while also erecting multiple Base Defense Turrets as well as other items to protect your site from enemy Locusts. When the Scarab's head cannot move, get your fleet of Wolverines right in front and have them launch barrages of missiles at the target to slow it down. Obviously, you must repeatedly improve your Wolverines to ensure that they are at the maximum level of upgrades so that defeating the enemies is a breeze.
- At the beginning of the Level, you start out with a population count of 7, a reference to Bungie's love of number 7.
- Another 7 reference is that the Super Scarab is powered by 7 power nodes.
- As soon as the level starts, the "Commentator" mentions "Firebase Ready" as if announcing the creation of a new base, but the base is actually a Fortress.
- Your MAC Blast may sometimes be unable to recharge. You also gain an extra shot afterward.
- There is a glitch in the level, which effectively gives you infinite time, if done properly. There is a garrisonable sniper tower - if you have the "New Blood" upgrade, garrisoning Marines in there will make the Scarab constantly fire at the tower. Due to the floating nature of the sniper tower, the Marines take no damage and an invisible wall stops the shot from penetrating. However, if you send a unit in the way of the Scarab's fire, it will return to normal and the glitch becomes useless. There are also spots near the Scarab where a squad of Marines can stand firing at the Scarab, while the Scarab beam always misses them; it's possible that the Scarab will keep firing at that squad of Marines for a long time.
- While the scarab would destroy any extraction vehicles, supply ships are perfectly fine. (Although this is most likely for gameplay purposes)
