|Head to Whistling Beaver Brewery, east of Henbane River||400 RP|
Liberate the Cult Outpost
Travel far to the east of the Henbane River, north of Jessop Conservatory to locate the Brewery. Begin your approach from the east of the Outpost where you can use your Binoculars to scan the enemies, especially the Marksman on the roof. Once you're ready, sneak down to the side here and climb the ladder.
Once at the top, climb onto the roof and wait for the Marksman to turn around, taking him out and disabling the Alarm if you wish. Head back down the ladder and into the door there, waiting for a Cultist to come and check the stock before taking him out. Head out back and dispatch one more Cultist on his own before you resume your infiltration inside the warehouse.
To the right is another lone Cultist, take him out and then head back into the main warehouse where the VIP awaits. Wait for the patrols to pass and then quickly take him out, moving his body to a safe location to avoid being seen. If you look into the corner here, you'll spot a pallet leading up to a window, wait for a Cultist to lean against it and take him out before taking out the final Cultist in this main warehouse.
Head through the bar and towards the window where a Cultist is sat just outside, from the safety of the window take out the Cultist. This leaves you just the final two Cultists out the front, wait for them to separate and dispatch them to clear the Outpost.
