Behind The Glass | Walkthrough Prototype Guide
Last update: 11 May 2016
You start on one of the rooftops. In order to begin the mission, you have to go to Mercer's sister, Dana. First, however, you must get yourself the Diveroll ability. Further missions will require specific skill, so I guess you just have to get used to it. When you're ready, enter the marker to start the mission.
You have to visit the GENTEK building in this mission. Firstly, enter the marker located in front of the facility. You need a military disguise in order to infiltrate this place. You probably already have one - all in all, you've consumed some enemies lately.
Once you enter the restricted area, approach the local commander. Only with his appearance you can access the building. Grab his and quickly consume. Note, that there are detectors all over the place, they're able to recognize you even when in disguise. If you start the alarm, run on top of the building - you can wait there for the alert to stop.
Once everything cools down, get down on the ground and enter the building through the main door. After the cut-scene, you'll land in front of the GENTEK facility. Run away from here if you don't want to be killed by mutants. Run towards the military base nearby, shapeshifting into a soldier on your way there.
Enter the building through the window in the roof. Now this'll be a slaughterhouse. Let's start with finishing a few soldiers (you might want to consume some of them to maximize your health). Once the infected enemies come to party, grab a grenade or rocket launcher - there are lots of these things in the corners.
Blow up all mutated opponents. Try to absorb some of them (those with red markers above their heads) - not only you'll save some ammo, but also regain a lot of health. Once you kill several mutants, the game will inform you that in order to make a progress, you must destroy the fuel tanks at the walls. Destroy them all in any fashion to complete this mission.
