Call of Duty: World at War

The game is a military first-person shooter with weaponry and linear levels to try a realistic war. Players are in the midst of action with NPC teammates. Missions involve clearing houses, planting bombs, or defending positions. Health regenerates when out of the fire. The game introduces a co-op campaign for up to four players, which is attached to two available campaigns. One begins in 1942 on Makin-Atoll, where Miller seeks vengeance. The other starts in Stalingrad, following Petrenko. Both of them recreate real missions. In particular, the multiplayer mode is similar to Call of Duty 4, including various game types and a ranking system. Players earn experience points to unlock weapons and abilities. Custom classes can be created for multiplayer matches.
