Deus Ex Human Revolution: Rescuing a TYM employee
Important! If by some reason you don't want to rescue the scientist, then you can skip this part of the walkthrough and continue the game by reading Step 3 (reaching the cryo-sterilization room).

Map legend: 1 - Entrance to the valve room; 2 - Entrance to the room filled with toxic gas; 3 - Datapad; 4 - Valve; 5 - TYM employee

Make a few steps forward and you're going to be stopped by a TYM employee. Apparently the scientist has damaged his suit and now seeks help before he's killed by the toxic fumes #1. You can promise to help him during a short conversation #2 or deny rescuing him. I wouldn't recommend leaving this person to die, because it's not going to take a lot of time to rescue the scientist and you'll receive a few rewards for doing that.

Your objective is to reach a valve which controls the flow of the gas and this can be achieved in two different ways. The first method is to use the closer door leading to Chemical Storage A4 #1. The door has a level 3 electronic lock, but after inspecting the northern part of the main corridor you would find a datapad with a code to the door - 4865 #2.

The second method is to go past the first room (the one with the valve) in search for the second door. This means you'll have to travel north and then turn east #1 and south. After a short walk you should find a new door leading to Chemical Storage A3 #2. Notice that the electronic lock on this door has only a level 1 complexity, however you should consider solving the mini-game only if Jensen has an Implanted Rebreather augmentation.

If you've used the door leading to Chemical Storage A4 (northern room) you'll be allowed to approach the valve right away #1 in order to get rid of the fumes. If you've used the door leading to Chemical Storage A3 (southern room) you'll have to quickly go through the gas-filled room, searching for the northern door.
Experience: 750 experience points.

You no longer have to work fast, so you should take some time and explore both rooms. The northern storage has several lockers and one of them is hiding a datapad #1 with four different security codes. The southern room also contains a small number of lockers. Open them and then start interacting with small crates blocking your way to the second part of the room #2.

Approach the TYM employee you've managed to save from certain death and start a conversation with him. The man will want to thank you somehow for your help and he'll advise to mention him in an upcoming conversation with a local guard named Kim so that you'll receive full access to the nearby facility.
