The game will come with a new coop game type named fire fight. And it is just like Gears of War 2 horid. Where you play against a increesing wave of covenent. As the game progresses the skulls you have collected turn on making the game harder.
Also the game will come with a beta of Bungies newest secret game, Halo: Reach! All you need is a copy of Halo 3: ODST and Xbox Live. The beta will be up for download shortly after ODST hit stores.
ODST will come with 3 new maps for Halo 3 & ODST. Collect the skulls on all 6 Mythic maps, and unlock all the vidmaster achevments on both H3 & ODST and have a linked gamertag to bungie.net and you will have RECON armor.
