Originally slated to arrive last month, it looks like the Mac version of Batman: Arkham City is on track for release by the end of December. In development at Feral Interactive, the game was released on consoles and Windows in fall 2011 and recently came to Nintendo's new Wii U.
Feral was responsible for porting the original Batman: Arkham Asylum to Mac last November. It has handled other high-profile conversions such as BioShock, BioShock 2, and Deus Ex: Human Revolution.
The Mac version of Batman: Arkham City will sell for US$40 and include all of the DLC released
