This one is free through March 26 and should be pretty fighting game fan friendly… lots of cartoon violence

Lighthearted (but violent) fantasy action with a kick-butt heroine.
Fresh off a big win, mixed martial arts champion Gunner challenges his friend and rival, goth metal singer and ultimate street fighter Freya Blackstar, to a rematch of their past battle. But when the outcome is not what he wishes, his resulting misery leaves him vulnerable to a mind and body altering supernatural influence. In order to save him before he goes too far, his friends will have to use all their strength and wits… and maybe a little help from the internet.
