Commentary Locations

This guide helps you find all 280 commentary locations in Deus Ex: Human Revolution - Director's Cut.

These pieces of commentary were added to the Director's Cut version of the game and consist of the game designers discussing the creation of Deus Ex: Human Revolution in substantial detail.

How to Use the Guide

This guide is designed to help you find all the commentary locations in Deus Ex: Human Revolution - Director's Cut.

To enable the commentary audio you need to open the menu and go to EXTRA > COMMENTARY and turn this option on.



Since the very first intro cutscene has commentary I recommend doing this before starting a new game. Also, I don't recommend activating commentary if this is your very first time playing Deus Ex: Human Revolution; the team regularly discuss spoilers and talk over most of the cutscenes in the game.

There are two types of commentary. The first type automatically activates during cutscenes and the second type you have to locate yourself and press a button to play. In this guide the locations are shown on the various area maps with the following icons:

A round icon indicates a cutscene commentary. In the general area a cutscene will or will have happened with a commentary in it.



A rectangular icon indicates a commentary that has to be manually activated. Go to this location to and activate it yourself.


You will know you're in the right location when you can see this:
The "Play Commentary" key can be changed in your control settings.

Each commentary is documented in this guide with the following details:

• The number shows which it is according to the maps in this guide.
  
• A description of where it is located.
  
• A quick overview of its content.
  
• The length of the commentary in minutes and seconds.

There are 280 pieces of commentary in the game. This totals 7 hours and 50 minutes of commentary. However 3 of these can not be found in the game and do not play over the cutscenes they discuss. This is most likely a glitch. I have inserted the missing commentaries directly in to this guide as videos so you don't have to miss out.

The sections of this guide are laid out in order of a complete play through of the game from start to finish. Several times during the game you will return to a previous area and new commentary may be available so make sure to follow the guide section by section to not miss anything.
