No co-op in story mode, but separate missions reminiscent of CoD4ís Mile High Club include cooperative multiplayer.
In the wintery bits of the game, snowmobiles will be used to escape attack, but itís unclear whether players will be driving or shooting from the vehicles. Ice walls can also be climbed by alternating between the two triggers.
A live-patching system will be implemented for online multiplayer, forgoing the need for a downloadable patch.
Game will run at 60 frames-per-second, with better detail than CoD4.
Riot shields, movable turrets and customized weapons for single-player enemies were mentioned.
Gameplayís a bit more open-ended than CoD4 but is still linear.
