Searching for the perfect versus or cooperative Xbox multiplayer game can be challenging–the game publisher says it plays four but what exactly does that mean? XboxMP catalogs games with detailed breakdowns of what the multiplayer experience actually entails.
You can search first generation Xbox games, Xbox 360 games, and Xbox Live Arcade games with a variety of detailed criteria including the number of players it supports for local, system link, and online play (it may be a deal breaker, for example, that the only way to play the game with 4 players is to have two Xboxes or an Xbox live account). In addition to the multiplayer game data each game listing also includes addition information about the general game play including peripheral support and other features.
