This trophy competes against:
The Mr Wise-Guy trophy in The Inner World worth 95 pointsComplete the game without taking hints from the help system. In other words: don’t press L2. In order to get this trophy, constantly use L2 to receive hints about what to do next. Once you've exhausted all hint opportunities, solve another step and then repeat. You should be able to obtain this trophy early on in the first scene, in fact, but I would suggest either restarting after getting this if so, or waiting until you have completed it once so this will be all that is left.
