The Warriors Street Brawl

On boss mode hit the first boss to the ground near the edge of the screen. I usually do this on the beach, just to make it a bit easier. When he is on the floor you can keep kicking him repeatedly make sure you move the stick towards him when your kicking to keep the stun on. He will rotate around on the floor a little bit its nothing too serious. He has enough health for this to be done if you do it early!
