Call of Duty's single player game is second to none as far as immersing you in the gameplay. The visuals and audio are simply unbelievable. If you enjoyed M.O.H., Call of Duty will surely make you forget that game. It is superior to any WWII shooter on the market in terms of realism. The selection of weapons is great, the scripted events are movie-like, and the Stalingrad offensive is mind blowing. Although the single player is a bit short, and finished easily, you will not get bored with it's superb multiplayer package. It sports deathmatch, team deathmatch, search and destroy, and recovery modes. All of which are a joy to play. If you are a fan of the genre, you owe it to yourself to pick up Call of Duty, which is the most fun I've had since Battlefield 1942 was released. Highly, highly recommended.
