Fight your way through the Scorn hideout to reach the Fanatic.
- Having made it past the last wave of Screebs, you can head forward through the Hollowed Lair.
- Head on through the newly accessible doorway and into the next chamber.
- This is a large room filled with machinery.
- Go over to the walkway going out over the pit.
- Carefully jump between the arms of the machine as you head along the walkway.
- These arms will pause for a short period of time in their rotations, and that is when you will want to jump through.
- Turn to the left and go on up the nearby stairs.
- This next platform leads to a large platform with a long walkway off it going to the right with The Hangman on it.
- Along with him, a number of Ravagers will be running down the ramp toward the Guardian as well.
- Defeat them, getting the Hangman to retreat, and you will hear from the Fanatic.
- Go on up the ramp the Scorned had been coming down.
- At the top of the first set of stairs is a pair of Raiders that will be attacking with their Crossbows.
- Kill them and head on up the 2 sets of stairs here.
- Just follow along the corridor in front of you from there.
- Run on through as the Fanatic rants at you.
- Be wary as you enter the next chamber, there is a totem that will explode when hit or you get close.
- Go onto the platform where the totem was and look past the rotating machine arms.
- Shoot down the next totem, causing it to explode well out of range of the Guardian.
- Jump across the gap, either through or around the rotating arms.
- From there, follow the pathway and the stairs upward to the left around the room.
- Continue through the hatchway into the next corridor.
- Run to the end of this one, where you encounter an energy barrier, and wait for it to drop.
- Rush in and start the boss fight.
