For the past year or so, I've been working on a minimalist one-page post-apocalyptic RPG called Tempora Mutantur. It is inspired by Simon J. Bull’s SotU Refired v3, based on the original Searchers of the Unknown by Nicolas Dessaux. It's not really Mutant Future - but it does feature spidergoats!
The rules have been through several playtest revisions and are now pretty much finalized. In addition to the Core Rules, I have created a variety of supplements. The following downloads are currently available:
☢ Core Rules / Mission Overview
☢ Subterranean Exploration / Wilderness Exploration
☢ The Creep / Mutations
☢ Relics Supplement
☢ Wilderness Encounters / Humanoid Encounters
☢ Children of the Metal Gods / Sleepers, Clones, & Replicants
☢ Den of the Morlock Mind Master
I am currently recruiting players for Play-by-Skype, Play-by-Comment, and Tabletop sessions. If you're interested, drop by the website and check things out:
