Survive. Solve. Save. Pick one.


Mothership is a sci-fi horror roleplaying game where you and your crew try to survive in the most inhospitable environment in the universe: outer space! You'll excavate dangerous derelict spacecraft, explore strange unknown worlds, exterminate hostile alien life, and examine the horrors that encroach upon your every move. Choose from one of four classes:

  • Teamsters, the rough and tumble workers. More versatile at first level, Teamsters can be anything from engineers, to pilots, to asteroid miners.

  • Scientists, doctors, researches or anyone who wants to slice open aliens (or infected crew members) with a scalpel. Become an expert in genetics or xenobiology - or protect your crew from deadly viruses.

  • Androids are an exciting and terrifying addition to any crew. Powerful due to their supreme intellect, speed, and near-immunity to fear, they tend to unnerve other crew members with their cold inhumanity.

  • Marines are here to shoot bugs and chew bubblegum. They're handy in a fight, and better when grouped together, but be wary when a marine panics because it could spell doom for the rest of your crew.

Note: Mothership is in Alpha, and is actively in development. We make slight alterations and changes between print editions and try to keep the PDF as up to date as possible. We’re hoping for a full final release of the 1st edition in 2020 based on feedback of this alpha.

Review of Dead Planet from The Gauntlet.

What are people saying?

This thing walks to the line of usability/performance art, looks down at, and does a jig on it with its tongue hanging out waggling, eyes all googley, while flipping the world off with both hands.
— Ten Foot Pole
Such a great example of design in RPGs... If I was gonna run a sci-fi horror game this is the only game I’d use.... Strongly recommended.
— Ben Milton, Questing Beast
I think there’s a pretty good chance I’m actually gonna run this.
