(1) Aggressive solution: Getting out of the construction site Deus Ex: HR Guide
Last update: 11 May 2016
Warning! Events at the construction site may have two different endings. If you try hard, you'll manage to save Malik, who is trapped in a shot down VTOL. Be warned though, because this may be very difficult, since you'll be forced to fight a combat machine and well-armed enemies. Additionally, it would be good to equip a heavy rifle or another weapon of this type and EMP grenades or Typhoon explosives. If you don't try hard or ignore the possibility to save Malik's life, she won't survive a massive attack of enemy forces. In this situation, the best solution is to let enemies continue attacking the helicopter and leave the construction site.
This quests starts not far from the crash site and the battle can be fought in several ways. A first option is to fight direct fights, and in this situation right after the battle starts, run south #1 towards the building located in the southeast corner of the battlefield. Once you're there, shoot or neutralize in melee combat one or two enemies standing close.
Turn west and note that there are two enemies with heavy guns. Also it would be best to eliminate them in melee combat #1, but you can also use a heavy weapon #2 and aim their heads, taking the advantage of the fact, that they are busy with shooting at the Malik's vehicle.
Hide now behind one of columns and regenerate your health. An enemy combat robot will be dropped onto the battlefield and your absolute priority is to destroy it as fast as possible. If you decide to use EMP grenades, then toss at least 2-3 of them at the bot. Another ways of destroying the robot are to use a rocket launcher or Typhoon ammo (the Typhoon Explosive System augmentation needed) #2. In the latter case it is good to have this augmentation maxed so the single attack can destroy the bot. An advantage of Typhoon ammo is also a fact, that it would probably destroy other enemies around the bot.
Right after destroying the robot, keep shooting at other enemies, first dealing with survivors at the lowest level, and then taking care of snipers. Opponents can be found on balconies of the both - east #1 and west#2 buildings.
Another way to fight the battle is to stay close to the start point (screen above) and using a good sniper rifle in order to liquidate enemies. This method though requires a large amount of sniper ammo. You'd have also to equip a rocket launcher in order to destroy the robot mentioned above from a distance.
Dealing with all enemies leads to the end of the battle. Malik will thank you for your help and fly away from this place in damaged helicopter #1. If you have heard during the battle a farewell message from Malik #2, it means that you didn't save your friend. In this situation you can repeat the whole battle or continue it.
If you have such opportunity it would be good to look around the construction site before leaving it. First of all examine all enemies' corpses and upper balconies, which can be reached using the stairs and ladders. Additionally I would advise to take a closer look at the east part of this location #1. With an EMP Shielding augmentation you can go through the area with electrical discharges, finding a small tunnel #2. There are grenades hidden in a small room.
Whichever method of you actions you choose, you have to reach the cargo lift #1. Call the elevator and wait until it takes you to the upper level. Once you're there head towards the only visible door #2. It will take you to the well known Kuaigan district.
Reward: 1000 experience points.
