Tier 1: Keep 8 Cultist Sappers Away From The Gates
Kill Cultist Sappers while moving South.
Tier 2: Find a Way to Stop The Monstrosity
When you find the Monstrosity, he is bashing a door, trying to break it down.
Start out by collecting Explosives from around the door. Don’t worry, the Monstrosity is busy beating on the door, he’ll ignore you.
After you have 5 explosives(most you can carry), go to the left side of the giant door and take the detonator.
Walk around the Monstrosity, right clicking the explosives to drop them onto the floor.
Back away and right click on the Detonator to blow up the explosives + monstrosity, ending the mission.
