[Played on Easy because it was a lazy Sunday] This game is really funny. It starts because your ship is under attack by some aliens, then you go to fuck them up for a bit and find out you landed on a giant weapon. So you go to find out more about the weapon and a floating robot teleports you around for a bit before you find out the weapon is actually going to kill the entire galaxy so the zombies can't spread. And the game ends with you not blowing up the galaxy or something. Shooting is fun, the pistol is great, the Flood are a scary enemy to face, and the enemy sounds are goofy. Looking forward to playing Halo 2 and the rest.
