There is a movie of various quality showing various aspects of the game such as the bomb in assault, the Brute shot, the pistol, the wraith, some of the beta levels, 4 different teams existing (Yellow, Blue, Pink, and Green) in a game, the jump pad-esq things (Thank god there aren't ladders), the interface (including the party system), the Covenant Beam Rifle... and its made me want to give Shotgun CTF a try in Halo.
