These solo roleplaying rules are intended to be used with Mothership RPG by Tuesday Knight Games.
Solo roleplaying works by trying to emulate the role of the GM by using simple dice mechanics to answer questions. These rules provide a yes-no mechanic, for simple questions such as "Is the hatch locked?". Open questions such as "What does the bar tender know about the last group of miners that disappeared?" are handled by selecting random (themed) words that are meant to give you something to improvise from.
As Panic is a key mechanic in Mothership the rest of your crew are controlled using a light version of the Player Emulator with Tags. The full emulator is available on Github. This light version is modded to work with the Mothership d100/xd10 system.
