Hint: Defeating Super Shredder:
Use the following strategy to defeat Super Shredder under the hard difficulty setting: If you are using Raphael, then Shredder is easy. Keep moving to avoid his attacks, and move in and hit him when you see him do the blue ice attack. However, for the other three turtles, Super Shredder will be too fast if you use the entire stage to fight him. Instead, move to either side of the screen and stay there. This way, you keep the distance between you and Shredder manageable. Move only up and down to avoid his red and green flame attacks, and move in to attack only when he flashes blue. Try to stay very close to him and be ready to strike. Be patient and do not go after him if he teleports very far away from you, even if he is flashing blue, as you will not reach him in time. For him to come to you and he will. Do not attempt to attack him when he is about to do the red flame or green energy ball. He will probably still get you a few times if you move too slow.
Hint: Defeating blocking enemies:
Whenever you face an enemy that blocks, jump with B, then kick with Y very soon after the jump. If done correctly, you should diagonally kick and break the blocker’s guard.
Hint: Avoiding throwing stars:
When someone throws a star at you, press Hit and the star will backfire.
