Activities

There are a total of three activities.

Abandoned Auger Mine: Embossed Fault

To find the Auger Mine Activity, head to the southwest of the Grindstone of the Worthy, near the Pigeonhole Point of Interest. You’ll need to follow the main story until the mines open up. Once they do, the seal will change from red to blue, and you’ll be able to pass through the wall to get inside.

Head down the corridor into the Auger Mine until you hit a big, two-level cave. Cross this cave on the top level, then take the corridor on the other side into the next one.

Here, cross the cave again and follow the path at the upper part of the cave to reach a cave with a pool and a large spine on the ceiling. From there, you can finally reach the vending machines to start the boss fight against the Skull Orchid.

Order Bunker: The Crawlcroft

The Order Bunker is in the center, south of the Grindstone of the Worthy. The access point is a cave in the southwest of the Order Camp location.

Locust Dispenser Location: To open the bunker door, you need a locust capsule. Head back to where you entered the cave. The dispenser is under the metal platform.

Inside the bunker: Cross the first room through the half-open door on ground level. You may have to crouch. The next room is a bit smaller with less resistance. There are two paths, one corridor to the left, which leads deeper inside the bunker, and one elevator shaft to the right, which goes to a small storage area with a weapons chest.

In the third room, you will meet heavy resistance again. There is an open passage to the north that leads to the bunker’s vending machines and the boss fight against Fractis.

Order Silo: Rustical Hurl

The Order Silo: Rustical Hurl is in the west of the Grindstone of the Worthy region. – Carved into a mountainside. Drop down to the Silo ground level if you haven’t done so. Enter through the ground-floor main entrance of the Creeper-infested area. Inside, you can grapple further up the building to reach the capture terminal.

Bobbleheads

Bobbleheads that grant XP when flicked.

Stopflow Bowels

At the northwest of the map, northwest of the Stopflow Bowels POI on the map, are two pipelines leading to the western ledge. Use the containers to climb up to the end part of these pipes to find a bobblehead.
