(5) Peaceful solution: Finding Eric Koss Deus Ex: HR Guide
Last update: 11 May 2016
Note! Three scientists located by Pritchard can be reached in any order and this has no influence on further course of the quest. In a description below I assume that you've already met Declan Faherty (Step 3) and Nia Colvin (Step 4). So you should start your present actions on second level of the northeastern Micro-Gen lab (otherwise scroll up to the description of Step 4 for detailed instructions on how to get there).
Definitely the easiest way to get to the Eric Koss's lab is to use the cargo lift. In order to do this, go to the western part of level 2 of the Micro-Gen Lab building and find the door leading to the warehouse G-23 #1. You can hack fourth security level electronic lock or enter a code 5377 or examine the left wall to find a breakable fragment (the Punch Through Wall augmentation needed) #2.
Look for an e-book and then move towards large crates in the western part of the warehouse #1. They can be moved using sing the Move/Throw Heavy Objects augmentation. Note that after moving them you'll reveal a cargo lift control panel #2. Call the lift and wait until it takes you to the room G-33.
If you can't use the lift or if you do not want to do it, you must use the stairs leading to level 3. So return to main balconies and look for a right staircase #1. Be very careful after reaching level 3 because this area is patrolled by two guards #2. It would be good to stun them, however make sure that no one notice you - also watch out for a security camera (if you've hacked the computer terminal on a second floor, it is disabled already).
As always spend some time on exploring this level - at the beginning I suggest to go to its southern part. The room G-37 #1 is open for general use. It would be good to interact with an unlocked computer terminal and look into one of the drawers - you can find a PDA with a code there #2. An adjacent room G-36 is available too, but there is only one interesting object inside - a computer terminal.
Your mission goal is the door leading to the room G-33, located in the northwestern part of this floor #1. A main problem is a security camera hang over the mentioned door. If you haven't disabled it using a terminal in the room G-25, you should do this now. But it is not over of your problems, because this area is patrolled also by a guard #2.
The best way to eliminate this Belltower soldier is to stun him during the melee combat, because it would allow you to get past laser barriers without problems. You could also look around this area. But if you do not want to attack him, wait for a good moment and follow him, taking the advantage of fact, that a barrier will be disabled for a moment. Eventually you need to reach the door to the room G-33 #2. Before opening the door you might explore rooms G-31 and G-32, but there is only one, not important computer terminal.
Regardless of your actions, you need to get to the lab G-33. Go to the southern room and examine the adjacent room G-34, finding a computer terminal and an e-book. Walk towards Eric Koss now (screen above) and start the conversation. Its course may slightly differ, depending on the fact if you've already talk with one of the other scientists, or you've reached Eric first. If you've followed this guide, then you had visited Declan and Nia already, so Koss is the last scientist you're talking to. Jensen will share with Eric details about planned diversion. You should also get a disc with copy of the Sevchenko's virus, which will paralyze the local system.
Reward: 250 experience points.
Note! A description of further actions can be found in the description of Step 6 (Uploading the virus to the security computer).
