Deus Ex: Human Revolution Walkthrough Part 16 – Cashing in Old Favors
This is your last chance to explore Sarif Industies. Be sure to hit up Pritchard's office as well as Jensen's to read the e-mails. Be sure to thoroughly explore the area and hack any remaining doors (if you are augmented for that). Otherwise head for the marked Staff Elevator to go up to Sarf's office. There after your meeting with Darrow and Sarif, take a moment to hack into Athene's computer to get a few more codes and some more story. Head for the Helipad and before you get too close, SAVE! There is a very big fight coming up. If you are after the pacifist achievement, be sure to visit the storage area on the helipad for a stun gun and ammo for it plus tranquilizer darts. You will want Gas and EMP Grenades as well a long with plenty of energy bars. Otherwise, a good number of frag grenades and plenty of ammo for your favorite weapons.
Construction Site
Things go very hard south here with the crash and the swarm of enemies. How you handle things here depending on what you are after. It is best if Malik survives so she can help you later on. On the higher difficulties you sometimes have as little at 15 seconds to save her so be ready.
Stealth (Malik Dies)
Head to the right, going up the ramp to the second level. At the top take cover behind the first column. Wait for the guards, in the back, no come up and join in the fight. Now active your cloak and go past the two replacement guards down the ramp. Use the elevator here and enjoy the fireworks from the Helicopter. At the bottom of the elevator head for the south east for the double doors. This is your one chance to explore the rest of the construction site so take advantage of it then go through the double doors.
Stealth (Malik Lives)
The clock is ticking immediately so keep on your toes. Go t othe right and down the stiars. Keep t othe right as you move forward. Take up a position by the opening you see in the wall in front of you on the right. Go through it and take down the nearby guard. Now throw a gas grenade toward the far left column to take out the Heavy nearby it and likely another nearby guard. Now active your cloak and move forward through the columns, around the wall and to the left to creep up behind a guard for a take down. Now look to your left, a Box Guard is likely to active there. Throw an EMP grenade at it to disable it.
Sprint to the southwest and use the stairs there to get up a level. There are three guards above so take a moment to replenish your drained energy. Reactive your cloak and move up to each of them for a stun or sniping with the tranquilizer rifle while cloaked. Deactivate it once they are down and again restore your energy. Head around the corner and climb the nearby ladder. Replenish energy if you can/need to. Now dash to the nearby sniper and take him out. After him, if there is anyone below, cloak and drop down. Take them down and sweep the area to ensure there is no one remains active. After that head for the southern area and take the elevator down. Exit to the right. Head into the southeast portion and start exploring this area. This is your only chance to do this.
Fighting for Malik
Remember, EMP grenades make quick work for Box Guards. It will help to have the Revolver with Explosive Rounds and the Combat Rifle with the seeking upgrade as well. Pull out the revolver and back it up with EMP grenades for Box Guards. Now head down the stairs after you deal with the initial wave of enemies. Take care of the next pair of enemies with a double take down or the typhoon. Turn left and use the revolver or a grenade on the heavies there. Keep an eye out for a Box Guard showing up. Look around for the snipers and take them down, one is on the top floor and the other just a level up. Need to be look for a stair case to climb up. That should account for everyone, but sweep the area to be sure (and to loot the bodies). Now head for the elevator in the south. You can explore the lower area then you can go through the double doors to exit the construction area.
