Dark Stars

Publisher's blurb: Get your players to inflict horror upon themselves! ... Drawing on source material from Aliens to Lovecraft, it details four archetypal Alien Threats, a trio of Outer Gods, and a ready-to-run scenario called "Project Carcosa." User summary: Dark Stars is intended to be used as an add-on horror mechanic for use in any game system - however, the included mechanic is sufficient for use as simple, standalone, rules-lite game.
