(4) Aggressive solution: Leaving the penthouse Deus Ex: HR Guide
Last update: 11 May 2016
I wouldn't recommend waiting for enemies to come to you, because after exposing your position (screen above) you would become an easy target for them. Instead move away from Zhao's hideout as soon as possible.
Get rid of the closest enemy units and then take cover near to the stairs leading to the main hall of the penthouse (screen above). Be careful here, because enemies will be coming from the left and from the right. Focus your attention on soldiers with heavy rifles, because they should always be the first ones to die.
A different method of getting rid of the soldiers is to throw a gas grenade at them #1. Most of them would lose consciousness and the rest would become very easy targets. Keep fighting until all enemy units have been defeated. I would recommend that you take some time to examine bodies of fallen enemies. Aside from credits and ammunition you'll also find a datapad #2 with a qilin password which will become useful later in the quest.
All the methods described above will allow you to leave main areas of the penthouse and to get to northern corridors. Ignore the elevator you've used to get here, because you'll have to go further to the north to find a second elevator (screen above). Listen to a conversation with Malik along the way to learn that you'll have to open a hangar door to ensure your escape.
Important! The walkthrough is continued in Step 5 (Opening the hangar door).
