No, Batman: Arkham City Won't Have A Multiplayer Component.

Fans even went to the trouble of constructing some elaborate hoax material to try and dupe gamers (and bloggers) into thinking the Arkham Asylum sequel would have multiplayer in some form. But Rocksteady's top-bod, Sefton Hill, has shot down any such rumours in an interview with IGN, stating that Bats' latest title will be a "single-player only" experience. Hill added that the single-player decision was made because the studio didn't want to substitute any resources from the campaign. "With the game now coming to the final stages, I can honestly say it would not have been possible to deliver Arkham City the way we wanted to if we'd have added multiplayer."

In an age where multiplayer is shoe-horned into every type of experience possible, it's refreshing to hear a developer stick to their guns and keep their entire focus on the game's campaign. Hats-off Rocksteady. Now, when can we get our hands on it?
