For this achievement you will need to start a playthrough in Episode 5 on Trailblazer difficulty. Don't worry with the second part of the description, cause on this difficulty, the hint button is inactive, so you can't press it.
The game isn't difficult to complete, if you get stuck in any part you can use any guide available, especially the one provided in the collector's edition. With this guide, the game is a breeze, and whenever you're stuck you can just go to the top menu and click on the strategy guide button, that it will take you to solution of the puzzle or what you have to find next. This DOES NOT void this achievement.
