It was founded in 2004, by Jamie Walker and Sefton Hill, formerly of the Argonaut Software studio  Several other Argonaut employees were also brought on board. SCi Entertainment who were later renamed Eidos was a founding investor in the studio, holding just over a quarter of the company shares.

Batman Arkham Asylum was released in 2009 to critical acclaim and huge commercial success.
