Fury when free a while back...I think.

there is also www.gunzonline.com - similar to rakions concept except with guns/matrix style moves such as dives, running on walls, fast paced etc... no martial arts though.

there is also rumble fighter which is pure pvp you should check that out if you want an... Ok fighting game.
