Ok so imagine this. A group of about 5 or so people explore and eventually get trapped in the abandoned mine shaft and they end up being there for about 20 or more years living off nothing but toxic sludge and radioactive water from a nearby ☢️plant causing them to look horrific like I’m talking skin bearly even one type stuff, they’re all skinny and pale dude to being in a cave. Also they’re essentially immortal zombies and can no longer fell pain they also can’t age anymore.
