I played this game as a kid, but a can't remmeber the name. The game had up to 4 players. Each player was represented by cowboy-style dressed man with a different colour. The game involved using karate-style fighting, guns, machine-guns and WHIPS (which were a powerful weapon taking out several guys at once, this is probably the most memorable thing to me) to take out huge masses of enemies. The game was very long according to my memories and the last boss was a mole looking guy with huge claws in a tank.

Nevermind, found it. It's Growl.
