"Perfect Dark Zero" features a campaign mode consisting of 14 missions that can be played co-operatively and a multiplayer mode where a maximum of 32 players can compete against each other in numerous types of deathmatch and objective-based games. Both the co-operative and multiplayer modes support split screen, system link, and the Xbox Live online service. The game was under development for five years and was originally intended to be released for the Nintendo GameCube and later the Xbox. During development, several intended features were canceled so that the game could meet the Xbox 360 launch.
