Earlier this month it was reported that Batman: Arkham Asylum had sold close to 2 million copies in its first month. Today Eidos and Warner Bros. Interactive Entertainment officially confirmed that the game has shipped over 2.5 million copies since launch. Superhero games haven't exactly had a great track record (with the Superman games being the worst of the bunch), but Arkham Asylum has been lavished with praise, garnering a Metacritic score in the 90s.
“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.”
“The tremendous critical and commercial success of Batman: Arkham Asylum sets a new benchmark for superhero games,” said Martin Tremblay, President, Warner Bros. Interactive Entertainment. “Rocksteady Studios created an excellent game and the sales numbers demonstrate how a powerful franchise fused with high-quality production resonates with consumers.”
Although the PS3 and Xbox 360 versions of the game have been on the market for over a month, the Games for Windows Live version launched just last week in the U.S. and Europe. The first downloadable content also just went live, and additional DLC is in the works.
