Now the control will switch back to Marcus. Head to the Blume building entrance and interact with the door controls to start the mission. Once inside, you have to sneak past to the right of the reception counter then go downstairs to reach the main hall. It has a lot of heavily armed guards so it will be a good idea to scout the room first with your quadcopter to identify the hostiles and targets. Your main goal is to access the main server farm by the stairs in the middle of the hall. The access door is secured by a CCT.
There are two access keys that you can hack as well; one from the guard and the other from the a laptop in the corner room of the hall. There are ceiling overhangs where you can hide your quadcopter from the view of guards below or when you’re sending your jumper to interact with the marked routers.
The one in the west is not that guarded so you can simply send your jumper to do the job or sneak in and do it yourself. Just be careful of the unarmed employees in the area since they’ll create a scene and cause a commotion, drawing the armed guards to your position. After hacking the first router to the west, you have to make your way to the second router to the east, inside the meeting room near the workstations.
Your next objective is to reach the CCT connected to the access door at the end of the stairs. You can also send your jumper to enter through the vent or have it take the stairs leading to the second floor conference room where the CCT is located.
Hack the CCT then make your way to the elevator at the base of the stairs. It will be easier to get rid of some of the guards since it will be hard to sneak to the elevator with a good number of them patrolling around the area. It’s up to you if you want to use lethal or non-lethal methods as long as you clear a path leading to the elevator.
After leaving the elevator, you have to reach the Air Gap Computer. The whole place is empty of guards and other sentries so you just need to walk in the door leading to the main computer. However, it will still be better to hack the CCT in the elevated office to unlock the access doors in the other side to make it easier to escape later on. The game won’t be cheap to allow you to simply walk out after completing your objective so make sure to place at least two proximity traps by the air gap computer’s main door entrance and the stairs.
Once ready, head to the computer and simply interact with it. After successfully hacking the computer, heavily armed guards will storm the place. They won’t know your location immediately but they’ll be aggressively looking for you and will surely come up to the main control room where the air gap computer is located. If you placed traps earlier, they’ll be triggered by now. If you want to remain hidden, you may want to stay put a bit behind the pillar by the second set of stairs and activate the proximity trigger there and place another one a bit further away to avoid chaining the explosion. Keep an eye to your mini-map and move only when there’s only a handful of guards relatively far from each other so you can pick them off one by one using melee takedowns or your stun gun.
You need to use your distraction skills to maintain stealth as you try to escape since creating noise will make your job a lot harder. You can eliminate all the guards if you want or work your way around them and head to the elevator.
When you’re back in the main hall, don’t let your guard down since a whole new platoon of heavily armed guards will arrive. They will be your last obstacle to freedom. Unlike the others, you don’t have to deal with this group entirely; you simply need to get past them which can be easily done using the mass communication disruption hack. You need to move to the office area since there’s a lot of small covers you can use to move around and take you closer to the main stairs. When you have the opportunity, make a run for it but be careful of the lone guard by the door; distract him and take him out with a melee attack then interact with the door to leave the building and complete the mission.
Congratulations for finishing the main story missions!
