this is a fighting game, and it's not exactly street fighter - you're pretty much looking at the original yie ar kung-fu in terms of sophistication here. no special moves as far as i can work out - down/right + B is supposed to do something, but it doesn't seem to work. the best thing about it is by far the character names - the first enemy you face (the one pictured above) is identified in the manual as "Beard Guy", for instance. there's also one called Hot Leg, and one called Corpse Face (who happens to be a jiang shi, which is something at least). oh yeah and it's either really hard or i'm really crap at it, because i can't even beat Beard Guy.
