This is the first level of the Halo combat-evolved Xbox game. It follows the game pretty well. Like the cafeteria and cryo-tube bay. The instructions are in the game. Tips MUST READ, COULD AFFECT GAMEPLAY: There are some glitches I need to let you know about that could ruin gameplay if not followed. First: Do not go thru the first door at the beginning before the trainer. Second: The grunts may seem to come back alive, but they really just have to be shot when they are shooting. This can be annoying, trust me, I know, you just have to time it right. Thanks for listening, have fun!
