Batman: Arkham City is a Games for Windows Live title, publisher Warner Bros. Interactive has confirmed to Eurogamer.

This comes following a Tweet from digital retailer Green Man Gaming, which claimed it had been told by Warner that Rocksteady's game was "Games for Windows but NOT a Games for Windows 'Live' title."

Gamers were first alerted to the situation in June when box art, which showed the Games for Windows Live logo, emerged.
