World at War includes a similar multiplayer experience to that which was established in Call of Duty 4: Modern Warfare. All versions of the game use a similar perk and ranking system and feature six different multiplayer modes, including team deathmatch and capture the flag
There are a group of three "killstreak rewards" that can be used to turn the tide of battle. The killstreak rewards include a recon plane, showing opposing players on the mini-map, an artillery strike upon an area, and attack dogs, which spawn and attack opposing players, which come with 3, 5, and 7 kills, respectively. They are available in all game modes, apart from team survival, and cannot be edited.
