After the PC release of Batman Arkham Asylum last week, Eidos announced today that it has sold 2.5 million copies (among all platforms). Before the PC release of the game it was at nearly 2 million sales.

Martin Tremblay, President, Warner Bros. Interactive Entertainment gives credit to the multi-award winning game. “The tremendous critical and commercial success of Batman: Arkham Asylum sets a new benchmark for superhero games.” “Rocksteady Studios created an excellent game and the sales numbers demonstrate how a powerful franchise fused with high-quality production resonates with consumers.”

Batman Arkham Asylum was released for Xbox 360 and PS3 the end of August, with the PC version releasing last week. There are already two DLC for Batman, “Insane Night” which released last Thursday and “Prey of Darkness” which will be available this Thursday, September 24th.
