Joystiq has word by way of LinkedIn of a new "top secret next-gen game for PS4 and PC" in the works at Interceptor Entertainment (Rise of the Triad) called Project Ascender. What they've pieced together is that this is due next year, and 3D Realms' Scott Miller is one of the 19 members of the development team. But remember, it's a secret. Shhhh.
