At the main menu go to the cheats section and as a cheat enter: auntmay. When you have done this push triangle, now go on the costumes section and select any one you like. Now push triangle again.
Now push to go the the part where you select the powers you want. Choose one of them as stealth and pick the other two you want. Now select the level you want play and during game play press select to toggle invisibility on or off.
