Perhaps the worst-kept secret of the show, Halo: Combat Evolved Anniversary is the original Halo title ported over to the Xbox 360 with a graphical filter giving it a next-gen kick in the nuts.
343 Frank O'Connor assured during a post-conference interview that the game is the self-same original, with players able to switch between the new graphical layer and the original visuals at the touch of a button.
Featuring the original campaign, the game will also offer online two-player co-op, and seven multiplayer maps reportedly using the Reach engine. Six will be conventional, while the seventh will be a Firefight match based on a classic locale.
The game will be released on November 15 at a reduced retail price, though the exact cost is yet to be revealed.
