Xenoscape RPG: 2 Book Slipcase Set

XENOSCAPE is a pen and paper post-sci-fi RPG, set in a very primitive raypunk style world; players will find themselves impersonating characters intent on surviving day by day on Materia, a planet where civilization and human presence is now a distant memory, where wild and lethal vegetation has regained global dominance and where mammoth and alien-like creatures dwell.

Forget about monetary trade, infrastructures, and even writing; whatever the Species you are going to roleplay, your primeval survival instinct will be your main and fundamental resource.
