Toribash is an innovative free-to-play online turn-based fighting game where you’re able to design your own moves. It is a martial arts simulator (yes, we do call a game with full body dismemberment a simulator) where you move your character by controlling joints on their body. As each of them can have 4 different states, number of possible moves is almost endless, which makes fights unique.

Main features:

Completely unique fights with players all around the world
Unlimited character customization: body colors, textures, flames, hairs and more!
Daily knockout tournaments hosted by the Gamemasters
Lots of ingame and forum events
Ability to modify the environment and characters using the built-in Mod Maker
Open market - trade any of your items with your friends or just give them for free!
An extremely long game genre name
