• Additionally, the game offers downloadable "map packs" that may be bought online. The addition of a cooperative mode, which allows up to two players locally and four online, and the advent of the Zombies mode, were new additions to the franchise.
• The game has more advanced audio and visual effects based on an improved version of the Infinity Ward IW engine. 
• Treyarch used the engine to add more destructible elements to specific landscapes and add realistic burns and limb amputation to character models.
• Although World at War is open-ended and offers the player many methods to fulfil goals, it otherwise plays similarly to earlier Call of Duty games in terms of themes and content. Teammates controlled by AI fight alongside players. They assist in completing the game's missions by giving cover fire, taking out foes, and opening doors.
