Part-time UFO - a HAL game where the alien is wholesome! ^_

Aww, I get it. Monsters need to relax too.

How about Party Hard 2? It’s a simple game where your job to kill all the humans! Good catharsis.

If you’re looking for a more one-on-one murder simulator (some monsters get stressed out at parties.) how about Overboard? Kill your husband on a boat, and try to get away with it! Good story game.
