It has been rumored for a number of weeks, but now it is official. Telltale Games has partnered with Robert Kirkman to develop multiple games based off of The Walking Dead comic book series. In a recent press event, Telltale revealed that it has a "multi-year, multi-platform, multi-title" deal and that we should see the first release late in 2011.
Specific platforms and pricing information were not mentioned, but their past offerings have been available on the PC/Mac, Wii, and Xbox Live. For more information and to check out an interview with Robert Kirkman, visit the source link below.
