Not only will it be four-player co-op, but The Darkness II‘s co-op will be “interwoven” with the main story (although that story itself is NOT playable co-op). The co-operative missions apparently branch off from the single player plot and allow the players to explore other environments that are connected to the story of the core game. And there was me think it’d be a mode where we got to control one Darkness tentacle each! Tsk. You can check out the full co-op reveal trailer below.
