Jessop Conservatory

Begin your approach to Jessop Conservatory from the north by climbing the radio tower and tagging the cultists. You will be able to see at least seven outside patrolling, more inside the house, and two alarms.

Use the zipline from the radio tower to descend to the house.

Head around the side of the house and into the open window to find your first target with his back to you. Take him out.

Creep downstairs and look out the open door to see the next cultist standing near a pickup truck. While still crouched, go left and over the small wall to get behind him and take him out, stashing the body behind the cover (press the cover button to crouch behind walls or objects) (press the cover button to crouch behind walls or objects) you approached from.

Head back towards the house but circle around the back to find another cultist with his back to you. Ensure the Marksman is not facing you and then take him out, leaving his body behind the back.

Head into the nearby greenhouse and take out the cultist inside.

Take out the patrolling cultist in the Bliss field and leave his body in this nearby field.

Continue up the path, taking out the cultist leaning on the wall before hiding behind the Nitrate bags in the corner.

Wait for the cultist who patrols this route, checking in on the caged animal, to start heading back. Quickly sneak over and take him out before stashing the body in the nearby Bliss field, staying crouched yourself.

Wait for the next cultist to walk by and dispatch him, leaving his body in this field too.

There should be two cultists left. One patrols the greenhouse you are in; wait for the perfect moment and take him out.

Approach the remaining Marksman in any way you like and take him out (a sniper can be useful) to complete the liberation of Jessop Conservatory.
