How to upgrade Power Level in TMNT: Shredder's Revenge
To upgrade your power level, play as the character of your choice and earn points. Each character will keep their power level as long as you save progress on Story Mode.

It may take more than one playthrough to get to max power level, but there is a rare achievement for getting to max power level with every character. Also, after beating the Story Mode for the first time, you will have to upgrade Casey Jones as well to get the achievement.
