Shutting Down Darrow's Signal

Chapter 15 - Tipping Point Several days after slipping aboard a Belltower ship, Jensen arrived at a remote laboratory complex in Singapore. Sarif's scientists were there, forced to create a unique biochip that could prevent people from using their augmented abilities. But millionaire Hugh Darrow, owner of the complex and willing participant in the Illuminati plan, had a different use in mind. Convinced that augmentations would be the death of mankind, Darrow used the chip to drive augmented people insane, setting off an event of horrific proportions that only Jensen can end...

M1 - Shutting Down Darrow's Signal is the final mission in Deus Ex: Human Revolution.

Get inside the tower and disengage the lockdown
XP 1250 for getting to Darrow. Confront Darrow. He may give Jensen the code to shutdown the signal.

It is at this point that you will start wishing you had made the PEPS part of your arsenal earlier on in the mission if you're not carrying it already. As soon as the lockdown is lifted, roughly two dozen crazed workes appear on your previously cleared way back to the elevator. They can largely be avoided, but unless you like being poked to death very slowly, the PEPS comes in handy seeing as they usually attack in larger groups and tend to corner and trap you if given the chance.

Since there's no XP reward for any of the workers and most of their loot is by and large hardly worth mentioning at this point, your main priority should just be to get through this part as quickly as possible.

Notable Exception: First time you encounter the crazed workers, there's a guard in the corridor to your left. Even if you avoid the others, he should be taken down and looted - doing so will net you 20 slugs for the Plasma Rifle. Once you had your fun dancing with the not-so-undead, take the lift down.

Defeat the Hyron Project

 * Enter the code in the central computer or hack it. Code 2012. Turrets surrounding the central computer will attack you, but they will not be able to reach you at the central computer.
 * Go to each of the computers at the edges of the room, hack or input passwords, and open doors.
 * Several humans and a robot will attack.
 * Once the doors have been opened, kill Zhao.
 * Alternatively just shoot Zhao directly with the laser rifle without doing any of the above.

Decide with 'truth' to broadcast
Eliza will ask Jensen to select one of the four buttons to push. Note that if you have not completed the side quests, then Sarif's or Taggart's buttons will be unavailable.
