Attractio [official site] has a simple but star-studded premise: in the grim dark future, Keira Knightley, M.I.A., and a Dalek are contestants on a deadly game show [er, that’s just people named Keir, Mia, and, wait, Dalek? -ed.]. If they want to live, they’ll need to solve physics-based platform-y puzzles by fiddling with gravity. Like The Running Man, but more falling. John played a demo way back in 2013, but now the full game is finally here, launched for your puzzling pleasure. I hope M.I.A. wins.
