The Lost Boys Walkthrough

Head to the Technician Lens in Zalissya. Speak to Lens and ask if he has any work. He will give you the quest to investigate the disappearance of four diggers: Max Saturday, Bedlam, Vasya Punk, and their leader, Mastiff. They were last seen near the tunnel south of Zalissya.

Exit Zalissya via the southern road and follow it until you reach the Dire Thicket point of interest on your left.

Continue south on the road a little further to find a bunker with an open door by the side of the road. Enter the bunker.

Drop down and proceed through the northern hallway, defeating any mutated rats.

Follow the hallway and search a backpack on the floor to find a fuse.

Enter the doorway to the left of the backpack and place the fuse in the nearby fuse box.

Head back to the hallway and continue west. You will encounter a room filled with electrical anomalies. Equip your bolts and throw them at the anomalies to pass through.

Continue through the next hallway to the west to reach another room with a large gravitational anomaly.

Before dropping down, eliminate any rats below.

Go down the stairs. To your left, loot a backpack for supplies.

Proceed through the room, throwing bolts at the anomaly in the ceiling hole.

On your right, you will find a survivor being thrown around by the anomaly. Quickly throw a bolt at the anomaly to temporarily stop it, then rush to the body to loot a PDA.

Read the PDA. It contains a conversation between Max Saturday and Dew, revealing that Mastiff was taken by a Monolithian and everyone else is dead, but Mastiff was taken to another location.

Exit the bunker by heading up the stairs on the western side and interacting with a lever to open a passage.

In the next room, navigate through another area filled with electrical anomalies using your bolts.

Exit the bunker. A new location will be added to your map in the southeast.

Head toward the new objective marker and you will find a run-down shack.

Exit the shack and go behind it to the east to find a smaller building with a padlock on the door.

Shoot the padlock to open the door. Go inside and pick up supplies from the shelves.

Go through the large hole to the right of the door and proceed through the tunnel to enter the shack from a different entrance.

As you enter, you will hear chatter from someone called “The Ninth”.

Go through the doorway to the north. Immediately to your right, you will find Mastiff recovering on a bed.

Speak to Mastiff. He will mention the attic.

Head up the ladder opposite Mastiff to find The Ninth. Speak to him.

When asked why he attacked Mastiff’s men, The Ninth will explain that a deadly mutant attacked them, not him. This is corroborated by the mutant body found earlier in the bunker.

As you discuss Mastiff's situation, the house will be swarmed by men who have come for The Ninth. You will be given the option to help him.
