The Killing Antidote is a small indie survival horror game, and almost everything on the Nexus page is installed the same way: a .pak file dropped into the game's ~mods folder, which you may have to create. A large share of the uploads are adult mods, but the unlock and utility ones are what most players actually install.
Ranked by hand, not auto-generated. Every mod links to its full page with install guide + compatibility.
