Searching for Proof

Chapter 9 - Corporate Warfare Arie Van Bruggen had no qualms admitting involvement in the attacks against Sarif, and even gave Jensen the name of the woman who'd hired him: Zhao Yun Ru, president of the Tai Yong Medical Corporation. Seems TYM wants to monopolize the augmentation industry, and hired black op mercenaries to destabilize its competitors. But to prove this, Jensen needs to infiltrate the biotechnology giant and locate recorded evidence...

M1 - Searching for Proof is a main mission in Deus Ex: Human Revolution.

Enter TYM's tower by passing through the pangu
Reach the door on the other end.

If you hack the level 2 device on the control panel, you will unlock a button that repositions the catwalk. This lets you bypass security by going to the room in the left and climbing up the ladder. This leads to a vent and a tunnel that drops down, but you will need the Icarus Landing Augmentation to proceed this way.

Find and view van Bruggen's Recording
At the end of the datacore room.

there are several ways to get to the server containing Van Bruggen's recording, if you have the pheromone augment active you can sweet talk your way past the guards to the server. however if you dont have that augment active but you would rather save the blood sheed, it isnt to hard to sneak your way past the guards provided you have a reasonable amount of energy cells and the cloaking augmentation would help exeptionally (it will allow you to walk straight through any laser detectors or cameras undetected!). On the other hand if you simply want to do it guns blazing (lethal of none-lethal) then it becomes a little tricky, as far as weapons go i would recommend a good old fashioned combat rifle and plenty of ammo, but if you prefer none lethal then the P.E.P.S if the weapon for you, again plenty of ammo.

once you enter the factory you will be meet with a guard who will tell you that this is a restriced area, again there a a few ways you can handle this, if you saved the man in the room with the toxic gas leak earlier, you can mention his name and the guard will let you through to pay back a favor. or if you didn't you could bluff and tell him you are a repair man here to fix a toxic gas leak and he will let you through, but if you choose this option he will only aloow you in the upstairs room making it harder to reach your objective if you are trying to sneak through. on the other hand you could simply bribe him 500 credits.

Later on you will be stopped again by a belltower guard who says you cannot enter with out a pass. now if you want you could allways shoot him in the face and be on your way, but there is a vent in one of the offices in that block leading to an empy office with a pass on the desk. but that pass only seems to get you so far as a little futher on another belltower guard stops you and exclaims that this area is authorised personal only. that means only three ways in, sweet talking, guns blazing or sneak in undetected. each way has their own pros and cons, but none are perticularly difficult as long as you are geared for the aproach.

when you reach the the door thoughs belltower soilders were guarding, (the code is 0703 to enter if you dont have the hacking skills) you will find a considerable amount of lasers patrolling the area. these can be bypassed easily if you have the cloaking augment or if you watch for a pattern in the patrols it may take a few trys but there should be a autosave after you enter the room anyway.

Once you have passed the lasers the last few rooms are fairly easy wether you are shooting your way in or sneaking past, you may want to take note, (if you are sneaking in) of the cameras in the last rooms if you are spotted by them they will raise the alarm instantly. you will also want to take note that the mechs at the end of this mission can be destroyed without voiding the achievement/trophy "pacifist".

Rescue a TYM employee

 * Level 3 computer hack (there is a pocket secretary with the passcode for the door at the end of the hall on a yellow trolley)
 * Round the back is a level 1 computer hack but requires Implanted Rebreather aug.
 * If you do manage to help him, talk to him and he will tell you to mention Lee to the guard ahead. This lets you get through the guard without having to bribe or persuade him.
