Alternate Ending 3 - Invasion

Sarge begins to taunt the Blue Team, but is killed by Aliens, who have brought an army of vehicles to invade and the two teams run away. A period of time passes and the Aliens now occupy Blood Gulch. Two Aliens begin to have a conversation on top of red base, using their language. They are unaware they are being spied upon by other Aliens on a cliff using the sniper rifle. These events mimic episode 1, and even the Aliens armor color mirrors the Spartan counter-parts.
