Ubisoft took the stage at the Sony press conference this afternoon to show off a new feature of Far Cry 3: Four-player co-op. Rather than take place in the game's singleplayer world, the co-op feature is an additional mode, offering a mission-based campaign, where players have to team up to accomplish certain objective-based tasks.

Ubisoft also showed off a map editor for the game, and mentioned that Far Cry 3 would also have extra content exclusively on Sony's console. The game is due out later on this year.
