Traps | Hints Thief Guide
Last update: 11 May 2016
You deal with traps ever since you complete the second chapter of the game and I recommend against ignoring them, because an accidental activation of a trap may contribute to Garrett's death or (in the best case) to alarming enemies to his current actions.
You can locate traps using focus, first of all because all of their elements are marked by the game in red (this also concerns connections between traps) and the devices that power them). If you do not have focus, you should, first of all, look for various pressure pates and try to walk around them at a safe distance. It is also a good idea to disarm traps that you run into, and here is where you can use gadgets to your aid (usually, this is what wire cutter is used for).
