Toribash is a turn-based fighting game. Create your own martial arts movies in single player sandbox mode,
or join the competition in the multi player modes. Focus is on tactics rather than reaction and button mashing.
The game features physics, full dismemberment, decapitation and comic style blood.
Toribash is awesome. You control the various joints and appendages of a ragdoll-like stickman and use your amazing flailing and grabbery to maim, dismember, behead and otherwise injure your opponent. It recently went into retail, but there's a free demo version (yey!)
you can win in two ways; a points system, based on how badly you hurt the opponent when the time runs out, and a disqualification, where one player touches the ground with something other than a hand or foot
there are 4 multiplayer rooms in the demo version:
Classic (regular distance, dismemberment, disqualification, grabbing and no fractures)
Taek-Kyon (far distance, dismemberment, disqualification, grabbing and no fractures)
2 Judo Rooms (close distance, dismemberment, disqualification, grabbing, dismemberment, no fractures)
Usually, there is a 120 frame "game", with each "round" taking up 10 frames in a regular game, however, in Judo, the game is 1000 frames, but each round is 70 frames, so careful planning is required to win. Judo games are usually decided on a Disqualification, rather than points.
Controls - Each joint is moved independently of each other
Z - extend/contract a joint
X - hold/relax a joint
C - hold/Relax all
Click Hands - set to "grab" mode (or back to Fist mode), hands can only grab one thing at a time
You can even grab yourself, often resulting in the horribleness in your own dismemberment.
Sumo, weapons, jousting, Wushu and other modes are available with the retail version
pretty steep learning curve, but highly addicting
very small download, and it's even available on OsX and Linux!
