https://store.steampowered.com/app/3037180/_Deep_Space_7/ Some kind of horror sci-fi TPS janky in a good way and sometimes unwillingly goofy. There is some customisation and a clothing system tho. The games runs on Unreal Engine so it should be simple to mod it. That being said I don't know if the body is entirely modeled or not.   Anyway the game is cheap and there is a demo if ya'll want to try it out.
