Call of Duty: World at War introduces co-operative play, bringing fresh meaning to the “No One Fights Alone” mantra with Wii also supporting a unique co-op mode for two players.

For the first time ever players will experience harrowing single-player missions together for greater camaraderie and tactical execution. The co-op campaign allows players to rank up and unlock perks in competitive multiplayer by completing challenges and earning experience points, adding continuous re-playability and team-based gameplay. Whether playing competitively or cooperatively – if players are online with Call of Duty: World at War – they will always gain experience points. Based on a player’s experience rank and rank of the player’s friends, Call of Duty: World at War will scale dynamically to provide a deeper level of challenge.
