The Immortal Souls Website now offers playable demos for the Windows and OS X editions of Immortal Souls, an independently developed RPG that's due for release on December 1. The game is described as a "comic-book role playing game about two vampires fighting to save their souls from the legions of Hell." There is a trailer showing off the demo, and should all this turn out to be your cup of tea, the game is currently available for preorder at a 30% discount.
