In order to complete the liberation of this cult outpost with a degree of competency, it’s worth working from the highest point downward, tackling foes on the upper gantries first. Achieve this by using the numerous grappling hook points on the north tower 
or following the Undetected route.
The facility has been cut out of the hillside, giving you a U-shaped perimeter running west-north-east, on either side of 
. You can easily tag enemies with binoculars and ranged fire from up here. Better yet, snipe the alarm panels easily and from a distance before venturing in.
The billboard to the southeast 
offers cover, equipment, and elevation, though you can’t spot both alarms, and you’re stuck here compared to moving around the perimeter woods to the north. Still, this is a good sniping position.
You can even move up from the main road to the south 
, using the low shop building with the helicopter on it 
to reach a ladder attached to the silos where a sniper is. Then you can reach the main roof 
and start removing foes.
The main building interior 
provides access to all parts of the base on the ground level. Interior stairs allow quick access to the roof of 
. However, this is a high-traffic area, so head here if clandestine approaches aren’t your preference.
Undetected/NoAlarms: Grapple and scale the communications tower on the zone’s far west side 
. Tag all foes from this vantage point. Zip-line to the top of the Green-Busch facility tower 
, drop down to the north alarm, and deactivate it. Silently kill the foe on the gantry. Head through the tower interior to the gantry heading south. Strangle the sniper on the silo roof, north of 
. Drop down to the low roof 
, and strangle the foe by the south alarm. Both alarms are now deactivated. Drop onto the low metal roof east of 
, then work your way around and through the main structure, removing ground foes without being seen.
