Now that the Ouya has forever changed the face of gaming as we know it, you may find yourself wondering "So what am I to do with my Ouya now?"

"We feel Ouya is leading the charge in disrupting the way in which games are both created and consumed today and, as our history suggests with our successes with both Red Orchestra and Killing Floor, we're not shy about embracing early, new digital distribution models," Tripwire VP Alan Wilson said in today's announcement.
