Time to rescue baby sister from the Warehouse in Brandon Docks. Head to the access point and hack in to camera on the computer and take out Nicky’s guard with the junction box. Now hack the phone for a quick call with sis to let her know you’re here. Sis may not know guns but she sure does get a good shot off on the guard that enters.
You have two options for getting Nicky out, guide her with the cameras or go in quietly and clear the area. While going in is my preferred method, enemies will become aggressive and kill Nicky if you are spotted, so this is the dangerous option but it puts you in control of the mission.
If you plan to take out the guards yourself you will want to exit to the north and climb the containers to up to the top floor, where a burner phone with the Audio File: Maurice Vega 06 is on a mattress. Enter when the guard is looking away and take him out and then look down where Nicky is to spot and Enforcer. You can either Lure him to the junction box and explode it or head down the stairs on the other side of the area and work your way around and take him out with a melee hit.
With the area around Nicky clear you can head across the bridge and use a Spec-Ops weapon to headshot the Fixers on the ground floor. At the back of the area, on the upper level, is a sniper looking out the window that you’ll need to take out to clear the area and then Nicky will escape.
Once Nicky is out you will only need to escape the area.
