Hairy Friend

After destroying the Monster Hood’s first omega guardian, head to the next area and find Rotten Walker. Talk to him to receive this quest. Follow the marker to the Katt-acombs hideout.

(The layout of the rooms in the hideout may differ from the walkthrough since the game re-arranges them per entry. However the nature of the traps and goons found inside is the same.)

Inside the hideout, you need to defeat 30 enemies in the next large room to find “traces” of Harry. After defeating all of them, two chests will appear. Loot them and head to the next area. You’ll find the computer there. Access it to complete the hideout. Talk to the Rotten Walker again to complete the quest.
