Who's excited?
I saw the commercial for it the other night during family guy and went apes**t. So crazy in fact that my girlfriend thought I was actually kidding and being sarcastic about the game.
I didn't have time to do a thorough search for sites of information about the game, but it's developed by Infinity Ward (because Treyarch making MW2 would be weird) and probably won't feature a Co-Op campaign feature (boo!)
Doesn't matter though, fighting on snowmobiles had me hooked.
