The PlayStation 2 game Call of Duty: World at War: Final Fronts does not include the Nazi Zombies game mode found in the main release of World at War. Final Fronts is a separate game with a different storyline from the main game.
According to IGN, the Final Fronts entry was developed separately from the main Call of Duty franchise. This game was released exclusively on PlayStation 2 and developed by Rebellion rather than Treyarch, who handled development of Call of Duty: World at War for Xbox 360, PlayStation 3, Wii and PC. Final Fronts also does not include any multiplayer elements.
