Back in 1995, Toy Story wowed audiences with sophisticated computer-generated animation. That same year, games studio Parallax released Descent, blowing players away with some of the first truly 3D, omnidirectional gameplay. Things have moved on a lot since then, but the classic game's creators, Parallax co-founders Matt Toschlog and Mike Kulas, are ready to stage a revival. Today, they've released Overload, a spiritual successor that brings back the zero-G combat that redefined first-person shooters (FPS) two decades ago.
