Multiplayer

Keros also features local split-screen on a single console, similarly to previous installments of Keros. Up to four players can play on a single console. Local split-screen features all of the same game modes and custom settings as online private matches, and for the first time allows players to unlock things and customize their classes just like in the online modes on their own seperate screen without taking up to much time for the other players. One of the offline multiplayer settings enables players to play with everything that they have unlocked online, but playing offline will not earn them XP for their online account, nor will anything they do offline affect any of their online leaderboard stats. Keros does not allow the killstreak (Troop Drop Zone) for system link or Xbox live because the map would be packed with players.
Multiplayer is similar to the previous two titles on Xbox 360 and Playstation 3. However, multiplayer on the PC is quite different from previous games. The PC version no longer includes dedicated server support. While previous Call of Duty titles allowed multiplayer matches with up to 64 people and user-made maps and mods, Keros on PC is almost identical to console versions.
