Part 23

Head down the staircase, pick up ammo, shoot the propane tanks in the back of the truck, and proceed through.

From the start of Bad To Worse (A43), head forward and look for Cog Tags (CT26) at the corner of the building.

After picking up the Cog Tags, make two left turns and approach the doors.

Take cover (press the cover button to crouch behind walls or objects) near the doors and snipe all enemies, using a shotgun for Wretches, or throw a grenade near the Cog Tags to plug the Locust hole, then use your shotgun for any enemies that climb up.

When the Locust hole is sealed, two Boomers will appear near the doors. Find the Hammer of Dawn nearby and use it.

Switch back to your previous weapon (important to get another Longshot later) and go through the now open door.

Enter the building and proceed until you reach the first greenhouse area.

As you exit the greenhouse, a Berserker will appear. Dodge its attacks and head through the door it emerged from.

Continue down the hallway to the next greenhouse area. You can try to lure the Berserker to knock down the tree in front of it.

Head forward through the area. At the bloodstain in the middle, find the Hammer of Dawn and switch to it.

To use the Hammer of Dawn, you must make the Berserker run into the green pillars to knock them down, clearing the way through the glass ceiling.

Lure the Berserker into the pillars by positioning yourself so it hits a wall and dances, then dodge. Repeat for all pillars.

Once all pillars are down, use the Hammer of Dawn on the Berserker when it is stunned after hitting something or stopping. It takes three bursts on Insane difficulty.

After defeating the Berserker, head up the middle to find a valve. Turn it to extinguish the fire blocking a hole in the wall.

Proceed through the hole.

In Hazing (A44), head left to find a doorway. Go down the hallway and peek around the corner.

If you have the Hammer of Dawn, use it on the Troika. Otherwise, snipe the Troika quickly.

Prioritize taking out the Troika.

When the Troika is dead, an Emergence hole will appear. Try to plug it, or position yourself opposite it with a shotgun ready.

Kill the emerging Locusts and Wretches.

Hop over the low wall in the doorway on the right side (from where you entered). The Hammer of Dawn is no longer available.

Head left from where you exit the hallway and find a Lancer.

Take cover behind a flower box and snipe long-range targets, using a shotgun for close-range enemies.

Advance to the bench at the far end where a Locust frequently takes cover.

Fall back to the bench and snipe all enemies that appear on the other side until a Boomer appears.
