The Treyarch-developed shooter will include four-player online co-op for the Xbox 360, PS3, and PC, while the console versions will also allow soldiers to pair up offline for local split-screen gameplay, with "a unique co-op mode for two players" reserved for soldiers waggling on the Wii. However, the game's online focus won't end with simply gunning down enemy soldiers, players will recieve persistent experience points for participating in both competitive and cooperative online battles.
