Seacat: the game you always knew you wanted to play, but didn't dare to admit.

A psychedelic metal roleplaying game.

A comic on every page.

A project made possible by hundreds of the nicest patreon heroes in tabletop roleplaying games.

Inspired by

Moebius’ mind-bending bande dessinée Airtight Garage. Blue Oyster Cult’s evocative Veteran of the Psychic Wars. The rambling melange that is the Heavy Metal movie. The surreal fantasy of Jodorowsky’s Holy Mountain. The impressionistic brilliance of Miller’s Fury Road. The semi-coherence of the Strugatskys’ Roadside Picnic or VanderMeer’s Annihilation. The neo-baroque pop metal of Ghost.

In Development On Patreon

Development version 0.6 and older versions are available exclusively to the heroes backing the stratometaship patreon. New backers welcome.

Join and help bring more mind-controlling sentient cats to roleplaying games!

Anyone had any similar generators?”
