The Far Cry games feature a robust single-player campaign with later titles offering co-operative campaign support. The games also offer competitive multiplayer options and the ability for users to edit the games' maps for these matches. The player often needs to work with freedom fighters attempting to regain control of a region from a ruling party, and may have to pit different sides of a conflict against each other through their actions. Some of the series' games have been more rooted in realistic conflicts, while others have involved elements of the supernatural or science fiction. Ubisoft Montreal, the principal developers of the series, do consider that all games share the same common fictional universe, and have reused some minor characters to maintain that, but otherwise anticipate each game can be enjoyed as a standalone title without knowledge of the other games..
