help needed remebering a game's title

hey guyz i need help remembering this game's name...i used to play it on those coin machines like 15 years ago.
the game basicly is just fighting bosses...the first boss is half woman half snake..the 2nd was like a skeleton and it can fly...the 3rd was a reptile warrior...and i remember a boss half man half scorpion...and another two twin bosses you fight at the same time..they had sort of knives and one of them keep jumping on the other's sholders then jump on..does any of that ring a bell?

help is very much appreciated
