Many watched the video from gargan about the creation of the Cave Dweller and it went viral.
This is a mod inspired by it. It has ~~simple~~ mechanics and behaviours, but definetely never fails to scare!
in the ~~next~~ this update you will be able to change settings and spawn chances. by M_Productions
