Eidos has announced that their recently released title Batman: Arkham Asylum, has shipped in excess of 2.5 million units to stores since launch.

“Batman: Arkham Asylum is one of the stand-out games this year,” said Phil Rogers, CEO of Eidos. “I’ve been following the great reviews and consumer blogs and I’m delighted that gamers everywhere love playing this game as much as we do.”

In Batman: Arkham Asylum, developed by London-based Rocksteady Studios, Batman finds himself trapped inside the confines of Gotham’s psychiatric hospital for the criminally insane, Arkham Asylum. The Jokker has set a trap and has conspired with the deranged inmates to eliminate Batman once and for all. Adding to the authenticity of the game are veteran animated Batman voice talents Mark Hamill and Kevin Conroy, who reprise their roles as The Joker and Batman respectively.
