If there's anything that the Marvel Cinematic Universe has taught comic fans, it's that a good superhero team-up can be the most exciting part of any superhero media. For video games, that's been the same as well. Even the best moments from Marvel's Avengers stemmed from combat scenarios where heroes banded together for coordinated attacks. Part of the appeal of the upcoming Gotham Knights comes from the same conceit, especially when there's four iconic Bat Family members as playable characters. The upcoming action RPG from WB Games Montreal has co-op for players to facilitate this, but only two players can match up with one another to fight crime in Gotham.
