Lust Doll v20.4 by Invidi

Lust Doll is set in a apocalyptic semi-modern/future world, where you start alone and confused in a dangerous place, with literally nothing (not even clothes on your back), and go on to carve out a piece of the world for yourself. There'll be a main storyline to follow, but the emphasis is going to be on making it a sandbox game where you just screw around and have fun.
