Having landed in the penthouse section of the building, there are many ways to get through this. When you land, the Stealth Tutorial will automatically begin. Complete it to be mostly done with the Adept of the Metaverse Achievement.
Open the hatch on top of the elevator if you jumped down the shaft or just wait for the door to open if you Check the Construction Worker's corpse for some more credits and then step out of the elevator.
There are at least 2 Guards in this room that you need deal with. One stands at the top of the stairs and the other to the North. You can either take them down with weapons or sneak up on them and get them with take downs.
Loot the bodies and then turn to the East. You will see the hallway there to search. When you start down this hallway, a vent cover will fall off the Eastern wall. If you want to start sneaking through the area, jump up into the vent
Going into the vent gives you the Traveler bonus. If you go through the door you have a few Jinn to deal with. You can easily snipe them or move in for quick take downs or simply gun them down. It is about now that you receive the final tutorial: Combat Tutorial.
Heading through the vents you will need to just move forward. You can find a heavy plastic case that you can move without too much trouble. Continue on forward from there through the vent.
Mark and then start either avoiding or eliminating the Jinn in the area. There is one that patrols around the Eastern side and then heads to the North. There is another Jinn who patrols in the lower area, following a similar patrol path. Farther to the North you will find another Jinn patrolling the area. This one, on the higher path, is easier to take down without alerting any of the Jinn on the lower level.
Make your way to the North on this upper level. Look to the East and you will find a door.
Head on through it and go past the staircase on your left. Head into the next room. Just on the left you will see a hole in the wall.
Jump on through it to find a small area filled with poisonous gas below you. Your Rebreather will protect you.
To get out of the poisoned area, head to the North and go through the vent that is in the middle of the area. It is just across from where you landed. There is an ammo box that you can loot for some next bullets.
Go on through the next vent and open the vent cover there. Once through it, immediately take cover. Behind cover, take some time to look around (and mark) the various Jinn in the area. Take some time to lure the nearest Jinn over to you by ducking out of cover momentarily. After that, perform a take down on them. After that, you will want to slowly thin out of the Jinn around the area. If you have a Rifle, pick off the Jinn that are farther away. Otherwise, start moving forward and take out the Jinn in this area as you go forward.
Having dealt with at least a few of the Djinn, go forward to the West and take cover behind the crates forward of you. Go to the right-hand end of them. Just ahead is a ladder. Take it on up and head into the vent shaft there. Go on through the shaft.
You can also head to the North and then turn to the East. You will find a second penthouse area to explore. This one has only a few Jinn in the area. Take out the pair of them and then head to the stairs leading to the upper part of the area. Go forward on the upper level and going out to the walkway to the West.
Follow it to the North. This will lead you directly to the room where the Jinn have set up the Signal Booster. Throw a Gas Grenade to knock out the Jinn in the room.
After that, go into the room and interact with the signal booster on the Eastern side.
With the signal booster disabled, it is time to meet up with the rest of the team. Head to the West from the booster. There are only so many Jinn left between you and the exit. Get back out to the balcony overlooking the lower area. Just outside this penthouse is another Jinn. Take them down and then look to the North.
As you reach the staircase going down, look to the right. You will see a few throwable items. Grab one and then throw it at the far wall. This will lure one of the nearby guards over toward the wall. Sneak up behind them and perform a take down on them (or shoot them with your gun) then take cover on this lower balcony.
Take cover on the lower area and find the last Jinn who is guarding the door forward into where the deal is happening. Deal with them using a Take Down or a weapon.
Open the door and go through it. There is just this last room. Take this time to reload your weapons and heal up if you were hurt on the way in as well as recharge if you used a lot of energy. A big fight is coming up. Interact with the keypad to hack it open. Open the door to trigger the next cutscene.
- Infiltrate the building
- Restore power to the keypad
- Seal off access to the Atrium
- Jam the signal boost (secondary)
