(2) Getting to the elevator Deus Ex: HR Guide
Last update: 11 May 2016
After reaching northern buildings, your priority will be getting to the elevator. It will allow you to explore underground compound. I recommend reading following description carefully, because there is also an easy path to the elevator allowing you to bypass all enemies and security systems in the factory, among other options.
If you've chosen a first option to enter the main building, then its exploration will start on the second floor. After crossing linear corridors you would find yourself on upper balconies. This is a good spot to attack enemies visible below, but I suggest doing this only after elimination the sniper in this area (screen above). If you do not have a weapon for such long distance then after a successful action you could pick a sniper rifle and use it to clear the area.
A much better solution is to avoid any fight at all. After reaching upper balconies look for an air vent entrance #1. Use the vent and after crossing a small tunnel go down ladders #2 to lower level.
Do not use another vent but look for one more ladder to get to lowest level. Now enter the vent #1 and after few moments you'll reach the exit. Note that you're now by the elevator #2 which is current mission goal. So you can go to the next area without eliminating any opponents.
If you have chosen a second option to get to the main building, you'll then start on the first floor. Head north-east focusing on reaching a small control room #1. You have to be very careful though, because this area is patrolled by at least one guard #2.
After securing the control room area it would be good to interact with computer terminal #1. It has third security level but if you met Sanders during the secondary quest Voices from the Dark, you already know the password - neuralhub. After logging in you'll be able to turn off two local security cameras #2.
Do not be too happy that the way to the elevator visible in the distance #1 is clear. There is still a big group of enemies around #2 and unfortunately it would be good to eliminate many of them. I recommend watching out for a sniper on upper balconies, because he monitors the main factory hall. If you do not mind force solutions, you can of course shoot all enemies or try to run towards the elevator as fast as possibly but this is not advisable.
If you've chosen a third option to get to the main building, then you'll start exploring it a bit off the way and depending of decisions you make you'll be able to get to the places described previously. If you want to go to the terminal which controls a security camera, then turn left #1 when it is possible. You have to bypass somehow a laser barrier, either by using appropriate augmentation or interacting with the control panel (a code to disable barrier is 7984) #2.
You can also head north, eliminating one guard #1 along your way. Watch out for a security camera and a small booth #2 where sits one of the opponents. Another mercenary patrols an area to the left.
It is worth to get into the booth described earlier, but you have to be very careful because a guard inside is very sensitive to sounds from the outside. In the booth you could find an upgrade, a PDA and computer terminal among other things. If you have a special augmentation (Icarus Landing System) you can now jump down #1, landing near the elevator which is current mission goal. Otherwise I suggest using ladders #2 which would lead you to the upper balconies described in the first option (watch out for the sniper there!).
All options described above lead to the elevator. You have to go inside and start it. Do not worry about opponents visible along your way, because they are not aware about you. Instead listen to a new conversation with Sarif. A main character will inform his boss, that he is inside the FEMA camp. Then he will be instructed to identify mercenaries' leader. Save the game now because right after you leave the elevator you'll have to be very careful.
An underground compound is made of two large locations. Each can be passed through with several options and all what you have to do is to reach another elevator which transport passengers to the lowest level, unavailable by default.
