(3) Peaceful option: Crossing by first part of the camp Deus Ex: HR Guide
Last update: 11 May 2016
Stand quick behind the closest rate #1, so a big mech visible in the distance can't attack you. Pick up an EMP grenade from the crate and wait until mech goes away. Also make sure that guards do not walk towards you and quickly move the right #2.
Keep moving to the right #1, monitoring opponents and mech movements. Wait until proper moment again and quickly move towards right door #2, leaving the main hall and reaching the staircase.
STOP because there is a security camera right around the corner #1. Wait until it turns to the other side and go upstairs. This is unfortunately not the end of surprises because there is one more security camera along your way #2. Also in this case you have to wait for a good moment and bypass it then.
Approach carefully the door leading to the upper balcony #1. This area is patrolled by three opponents and if you do not want to trigger an alarm you have to bypass them or eliminate them skillfully. If you do not mind stunning your opponents then start with the one, who patrols a balcony closest to you #2. Be sure to pull away his corpse to place where it is not visible.
Now you should take care about guard who patrols an eastern part of balconies #1. Pull away his corpse and then deal with his buddy #2. If you do not want to attack them, you must use a camouflage and other tricks. There are not too many good covers on balconies where you can hide and wait for a good moment.
Regardless of how you have dealt with opponents, you have to go to the control room and the best is to approach it from the east #1, and that's because the western side is blocked #2 and you should use improved jumping or extraordinary strength.
Once inside the control room, head towards the eastern door #1. Cross a small storage room and follow the only way #2, stopping when you see two opponents below. After a while guards should split up.
Map legend: 1 - Main control room.
You can now stay on this level or use a ladder and go to the lower level, dealing with a guard there #1. If you've chosen a lower level then stop near another control room #2.
Look around the room, finding a PDA with a login wks0010 and a password usprotkt. Interact now with a nearby computer terminal #1. It has second security level, but you can use a password obtained lately. Read messages and approach second computer terminal #2. Enter a password neuralhub, which could be obtained from Zeke Sanders during the secondary quest Voices from the Dark.
Depending on how well your hacking skills are, you could make you further way easier (screen above). First of all I suggest turning off all security cameras. Moreover there is a possibility of changing the configuration of defensive turrets. If you have this possibility, turn them off. do not recommend reprogramming the turrets, so they start eliminating enemies. The reason is simple - it would trigger the alarm and you would lose a chance to get extra experience points for remaining unnoticed.
You have to choose now a starting level for exploring the second part of the camp. Both options are interesting, but if you return to the upper level -2 (the ladder), you will be able to enter the additional room #1. It is worth to break into a nearby computer terminal (password neuralhub) unlocking a way to a small armory #2. A description of further actions can be found in the description of Step 4 (Crossing by second part of the camp).
