From publisher blurb: A "1-bit" low-fi conversion of MOTHERSHIP: Sci Fi Horror RPG by Tuesday Knight Games. To fully use 1-Bit Mothership you'll need a copy of the original game which is free (although you should buy it, along with the excellent modules). Features: Coin Flips (1 bit randomizers) rather than dice rolls! A coin based skill system. Streamlined and simplified rules. Designed for maximum compatibility with Mothership modules. Very simple conversion guide.
