Deathloop Goldenloop Update - Where To Find Everything New

gamespot.com:

Deathloop has finally made its way to Xbox Series X|S and Xbox Game Pass and Arkane has released some new content on all the game's platforms to celebrate. The Goldenloop Update adds a new weapon, a new boss, a new Slab, and an extended ending. All of the new content is designed to make your journey through Deathloop a little easier, so here's where you can find all of the new stuff added as part of the Goldenloop Update.

The biggest edition in the Goldenloop update is the addition of the Halps Prototype, a new laser gun that is very powerful and has high ammo capacity. The Halps Prototype can be found in The Compound in Dr. Wenjie's lab. The Halps is tucked away in the corner of the green building. You can either use the weapon itself to destroy its container and grab it or return at night when Dr. Wenjie takes the weapon out of its case. This powerful weapon can incinerate most enemies, including Visionaries, in an instant. Check out GameSpot's Halps Prototype weapon guide for a more detailed explanation of how to acquire the weapon.

The Fugue Slab can be acquired by defeating the Garbage Collector in Karl's Bay. Head to the bay in the afternoon and head to the cliff side near where you enter the map, on your right side after exiting the tunnels. You should see a bunch of water with a plane on the right side. In this area there is a tunnel that leads down to the trash compactor area. Down here is where you can find the Garbage Collector, who has Frank's Slab, the Fugue Slab.

Now, the Collector is an incredibly tough enemy. He is decked out in all white-armor that is either completely bulletproof or makes him really resistant to it. After unloading all of my ammo and grenades into him, he was still completely unphased.
