According to an AICN report, a videogame adaptation of The Dark Tower is in the works and will appear alongside the movie's supposed May 2013 release.
The report says that the game on the IP, based on the Stephen King novels, is "being planned that will further utilize elements from the books".
There's no word yet as to who, if anyone, could publish the title. Or who's making it. Or anything else, for that matter.
