(2) Defend the attack on the facility | Prologue Deus Ex: HR Guide
Last update: 11 May 2016
Go to the elevator #1 located on the left and interact with a control console. You have already an access code to the elevator - 0451 #2. You can enter it by using the keyboard or the mouse to click on the buttons. Do not try to start the mini hacker game, while you do not have the necessary skills. Enter the elevator and use a control panel. Elevator will take you to a new level.
Leave the elevator and take the only possible path. After reaching the partially lowered barrier #1, duck (default - the C key). Continue to walk, reaching after a few moments the place where you see the execution of two scientists. Use now the blazing left passage #2.
Once you get inside, go to crates #1 located in front of you. Press E key to raise the upper chest. Put it somewhere on the side and notice that you've uncovered an entrance to the air vent. Jump on the lower chest #2, open the vent (E key again) and go inside.
Go through the whole vent, reaching after a few moments to the new grille. Exit the vent and use a large hole in the wall #1. I suggest saving your game here, because you're getting closer to the first group of opponents. You need to locate door #2 leading to further parts of the facility.
Enter the room and hide behind one of the covers (this is done by holding the right mouse button by default). Opponents will appear soon on the upper balcony. It would be good to attack them before they go down the platform at a lower level (screen above), because otherwise they could easily surround you and throw grenades at you. Shoot with short bursts of the combat rifle, do not lean out from the covers for too long and hide behind it as soon as Jensen gets serious injuries.
After the fight pick up the ammo from fallen enemies and go up the stairs to the upper level. Head here to the new door #1. Follow the next hallway, using the jump option (default SPACE) after reaching the small obstacles #2. Crouch and carefully approach the entrance to the new room occupied by enemy units.
I suggest to shoot two enemies from around the door (screenshot above), surprising at least one of them. Be ready to deal with a third mercenary, who should move in your direction after a moment. You cannot let him to get close to you.
You can now head to the only possible way out of the room #1. Follow the main corridor, again using the crouch option on the way. Watch the interactive cut-scene involving the member of a hostile organization using implants, and save your game before you decide to enter the new room #2.
Move carefully to the railing of the upper balcony. It is worth to shoot your opponents when they are close to each other (screenshot above), which reduces the risk of wasting ammunition. If the enemies will move to the place where shooting them from the balcony is not possible, change your position slightly, heading towards the ramp leading to the lower level. Remember to not let enemies get close, and hide behind a veil whenever the hero is seriously wounded.
After winning the battle go down and head toward the blazing passage #1. Follow the only possible path. When you reach one of the next passages #2, game will show longer cutscene, ending the prologue at the same time.
