From itch.io:
In The Cleaning of Prison Station Echo, PCs are nighttime janitorial staff brought in to clean a corporate-run, high-security prison. Their shift goes wrong when an accident in the hidden basement lab releases a rampaging horde of hallucinating test subjects from XeroCorp’s top-secret Super Soldier program. Trapped in lockdown, with all access to the outside world cut, PCs must navigate the chaos of crooked guards and desperate inmates. If they don’t solve the mystery hidden within the isolated prison moon quickly, the real “cleaners” will erase all traces of their existence.
The Cleaning of Prison Station Echo is a 52-page, full-colour adventure and sandbox for the sci-fi horror RPG Mothership. Professionally laid out by Mothership designer extraordinaire Eric Hill and edited by Matthew K, the zine is chock full of adventure hooks, unique items, and a huge cast of scheming NPCs. The adventure is brought to life through the glorious psychedelic line art of Evlyn Moreau and fantastic maps by Guy Pradel.
