Developers of the co-op Action/RPG Titan Quest have formed their own studio a few months after the previous studio, Iron Lore, was shut down. Best of all, the developers have actually bought back the rights to the a game they were working on called Black Legion.
Black Legion is an Xbox 360 Action/RPG being developed by Crate Entertainment. Currently they are shopping the game around to different publishers.
"One of our real goals [with Black Legion] is to take the solid game play we established in Titan Quest and repackage it to make it sort of grittier and more appealing to the mainstream audience" Arthur Bruno - Crate Entertainment Founder
Lets hope whatever Black Legion is, it has co-op.
