The End? Trophy in Teenage Mutant Ninja Turtles: Mutants in Manhattan

For this trophy, you need to complete all levels on a specific difficulty. Once you choose a difficulty, it's recommended you stick with it throughout just to make sure you get the trophy as the game keeps a tracker for which stage is beaten on which level. However I recommend just playing on Easy since you need to beat the game on Hard anyway. This means you can get a good feel for the game, get this trophy quicker, enjoy the story and give yourself more breathing space if the A.I messes up on the bosses. This trophy should unlock either during the results screen on Shredder's stage, during the final cutscene or during the credits.
