Switching Supply is one of the many water-related quests that must be completed in ARK Raidersand this happens on the map of the cosmodrome.
Switching the Supply begins after you receive it from Celeste. The quest involves turning on a valve in the tunnels of the Cosmodrome. Valve placement can be quite confusing and this guide will make the task easier for you.
Walkthrough of the ARC Raiders quest “Change of Supply”
The Supply Switching quest can be broken down into the following parts.
- Find the tunnels under the spaceport.
- Find and turn the valve in the tunnels under the spaceport.
Our first task is to find the tunnels running under the cosmodrome map. There are several ways to enter the tunnels. I've marked the entrance where it will take you the least amount of time to reach the valve.
You will find that part of the top surface of the tunnel has collapsed in the area I marked above. The spaceport tower will be to your right and you can use the opening to go down into the tunnel. When you're done, turn back and there will be a valve on the wall to your right.

Get close to the valve and you will be able to interact with it. The valve is hard to miss because it is illuminated by a gas lamp on the wall. Switching the power source does not require successful removal. Just talk to Celeste when you return to Speranza and you can complete the quest.
