In the “Switching the Supply” quest in ARC Raiders, you’ll be working with Celeste to solve a water contamination problem. The plan is to redirect clean water from a reservoir hidden beneath the Spaceport. To do this, you’ll need to go into the tunnels, find the valve, and turn it to reroute the flow. It’s a risky job that needs to be done in one go, so make sure you’re ready before heading out.
Switching the Supply Quest Guide
You’ll get this quest from the trader Celeste, and it has to be completed in one go if you leave or die, you’ll need to start over. There’s a water reservoir located beneath the Spaceport. If you can redirect that water to our area, it should give them a bit more time to handle the contamination problem.
Your goal is to head to the Spaceport and look for the tunnels underneath it. Once you’re down there, search for a valve and turn it to complete the main objective. When you finish the quest, you’ll receive the Spaceport Warehouse Key along with 28,000 XP as a reward.
Try to avoid areas with heavy enemy activity on your way to the tunnels. It’s a good idea to bring a few teammates along to watch your back. Once you reach the valve, turn it as fast as you can, then either move to a safer spot or head straight for extraction.
Finding the Tunnels Under the Spaceport

Open your Spaceport map and head to the area right in front of the launch towers. Once you’re inside, you’ll be getting close to the valve you need to find. Keep moving through the tunnels until you spot the valve on the wall. Interact with it to turn it and complete the main task.
