This can be done on local. Load up streets of rage, first level and wait for and enemy to grab you from behind. Once they grab you on your controller hit Jump jump attack = B B A ON CONTROLLER WITH DEFAULT SETTINGS. This will throw your enemy unlocking the achievement. Another easier tip sign in a second controller I was Blaze on controller one and axel on two. start the game and with player 2 grab player number one, on controller one then hit B B A.
