Summary
- Your objective is to find the tunnels southwest of Launch Towers then change the red valve on a distinct yellow pipe.
- To find the valve, enter the concrete slope opening then turn around at the bottom and continue walking until you spot it on the right wall.
- Expect frequent encounters with other raiders as Spaceport is one of the high-risk areas. Prepare for potential combat and move quickly through the tunnels as much as possible.
Can you finish Switching the Supply quest in ARC Raiders? It’ll task you to fix Speranza’s contaminated water supply by venturing into the dangerous tunnels beneath the Spaceport. However, the tunnels can be tricky and other raiders may spoil your plans. So, here’s how you can complete this quest instead!
What Is Switching the Supply Quest In ARC Raiders

In this quest, your objective is to find the underground tunnels at Spaceport and interact with a valve to change Speranza’s water supplier. This quest takes place in the center of the map, raising the risk for potential encounters with other players. Its tunnel system runs entirely around the base of the Launch Towers, creating an extensive underground network.
While straightforward, it is filled with hazards like exploding ticks that are hard to eliminate. You can quickly complete this quest once you know the exact location. However, some players struggled finding the correct entrance point and the specific valve due to maze-like design.
Where Is The Tunnel Entrance

You have to know exactly where to enter the tunnels so you can efficiently complete this quest. Instead of exploring the entire underground network, there’s an entry point which leads you close to your objective. Then here’s what you need to do after:
-
- Search for an opening on the ground directly southwest of Launch Towers.
- Look for a caved-in section where the ground collapses to see a concrete slope leading downward. This will serve as your entrance.
- Head to the marked location and walk down the concrete slope to enter the tunnel system.
Using this entry point saves you time compared to other entrances across the Launch Towers perimeter. Also, these tunnels are poorly lit and filled with potential threats that may compromise your mission. So, enter at the correct location to minimize your exposure to both hazards and enemy players looking for loot.
Finding and Turning the Valve

Once you’re inside the tunnels, the process becomes quicker and easier. Follow this navigation guide so you can find the valve instantly:
-
- Turn around at the bottom after descending the concrete slope.
- Go deeper into the tunnel, walk forward for several meters while keeping your eyes on the right-hand wall.
- Look for a yellow pipe attached to the tunnel wall with a red valve wheel mounted on top of it.
- The valve you’re looking for has a yellow mark that helps it stand out during dim lighting conditions.
- Once you find it, approach and press the interact button to turn the valve.
- Hold this button until the interaction completes.
- Afterward, it should switch Speranza’s water supply from the contaminated source to a cleaner alternative.
How to Stay Safe During The Quest

While the quest seems easy, it is located in the Spaceport which is one of the most contested locations. You’ll likely encounter other players during this mission, especially if it is placed at the center of the map. It attracts fellow raiders searching for loot while the confined tunnel spaces create dangerous combat scenarios.
So before you enter the tunnels, make sure your loadout is suitable for tight spaces. Also, the tunnels have exploding ticks that pose threats during your exploration. Move cautiously and listen for audio cues to stay aware of enemy presence.
Consider completing the quest during off-peak hours or coordinating with teammates who can cover while you switch the valve. Plus, plan your escape route as the tunnel’s single entrance can become a chokepoint once hostile players arrive.
Alternative Tunnel Access Points

There are several other access points throughout the Spaceport area. However, the southwest entrance near Launch Towers serves as the fastest route to the valve. Some alternative entrances are connected to the same tunnel network but require more navigation.
You can enter through other collapsed sections around Launch Towers if the primary entrance has camping raiders or is blocked. Although beware as you have to explore more of the tunnel and raise your exposure to threats.
Final Thoughts
Switching the Supply quest is one of the easy tasks you can immediately complete with the right strategies in ARC Raiders! All you need is to find the primary tunnel entrance within the Launch Towers so you can immediately locate the valve. Then, avoid attracting other raiders’ attention to prevent combat and keep an eye on ticks inside the maze-like tunnel.
