All you that have xbox live, I will own you the day it comes out. xbox live name is auiotour. I got to play it at microsoft for many weeks in a row. Multiplayer. Single Player. Haha, and when you guys get to the last boss. Wait for the allies to run in with you, hit sarge in the back of the head tell he fails off. (due it as fast as possible.) now the boss will jump down after him and the boss can not be beaten now. Now when you also do this, you will get an extra dot on your radar. that occasionally goes past your radist. If you stand on the edge and look for it. You will see that flying sphere that is in much of halo 1, and 2. Flying around with a girl moving with it, but really skippy. When I tested it a week before dead line it was still in the game (after 4 months of them knowing about it). Also for those of you, Guns/ammo is limited on the last level! (your flying and you fly with a huge scarab like creature. (your almsot at the end) Make sure to get all the ammo you can!
