|Earn a 100% skill score in one case.|
This set of achievements are the hardest to get in the entire game. In order to get 100% skill, you have to choose the right fingerprint the first time, click EXACTLY where the identifying qualities are, and you MUST match it to the correct area. You also need to use the correct tools whenever prompted. Lastly, you have to match the chemical side bars to the chemical itself PERFECTLY. Use the video walkthroughs to do this.
