"Will the game be available on Steam?

PA will be available on a wide variety of distribution platforms, including our own: UberNet. We will absolutely submit the game to Steam for approval, but its Valve's decision. Its possible by the time we release that Steam Greenlight will be the way to go and if so, we'll use that."
