HellMOO is a text-only multiplayer online-game, taking place somewhere in the far, post-apocalyptic future.

HellMOO

I’ve played it only for a short amount of time, but it’s pretty crazy. Eating dogs, beating up clowns, taking drugs and making out with other players - basically you’re able to do almost anything that crosses your contaminated mind.

At its core, it’s still a conventional Adventure-RPG with everything that entails: Levelling up, buying better weapons, exploring increasingly dangerous areas, completing missions… but that’s not why you should play it. You should play it because it’s a) lovingly written, b) probably runs on your computer and c) makes for a great opportunity to meet other deranged people online. Oh yeah, and it’s free too.
