Stand into jump,
Normal into turbo 2,
Level 1 into level 3.
After this, play the recording mode
This should make your enemy gets hurt when you hit him/her, then first, use any move to hit your enemy. But DON’T KILL HIM/HER!!! Lastly, use the Super Move D FD F, D FD F + Kick to finish HIM/HER. He/She should be hanging in the air. P.S. If you want to have more fun, press x when the K.O. sign came, Rolento should throw a bomb, and your enemy should drop from where he/she is hanging, but he/she will be frost from the pose that is getting hit!!!! Finally, after you do all this tricks, you MUST Restart SS Zero 2….. Sorry
