got this from a friend on the local audi forum.

its a flash site that lets you challenge each other by fighting.
you can gain experience, get more weapons animals that fight for you...special abilities, etc

you can join my dojo by clicking on this link http://s-car-go.mybrute.com
you dont need to register on anything like that, but you can add a password to your player so no-one else uses it.

enjoy
