The sheep are in their pen, about to be slaughtered by chaos unless they can break out of their world. Brought to you by 5bp, the company that produced Chaos Head Noah and Stein's Gate, Dunamis 15 continues in the vein of sci-fi adventure. The game takes gamers from Tokyo to an isolated island where Ceres Academy is built on. At first glance, the school seemed normal, but what it truly held is a laboratory for scientists and a prison for the clones. When an experiment went astray, the clones went berserk. To survive, the clones need to make some impossible decisions.
