Navigating the subterranean corridors of the Spaceport map in Arc Raiders requires both sharp tactical awareness and clear objective tracking. Assigned by Celeste to secure a cleaner water pipeline for Speranza, the Switching the Supply mission challenges players to breach underground channels and manually re-route vital resources. Understanding the exact route and target locations ensures you can execute this task smoothly without getting caught in heavy crossfire.

Locating the Spaceport Underground Tunnels

Your primary objective begins by making your way toward the central district of the Spaceport region near the Launch Towers. While several entrance points exist around the perimeter, the most direct path involves descending into the large structural breach right in front of the main towers. Dropping through the crumbled concrete ramp instantly registers the first mission milestone.

However, because the surface surrounding the Launch Towers is heavily contested by hostile ARC units and rival players, approach with extreme caution. Utilizing stealth skills or taking outer access hatches can help keep a low profile before heading underground. Once you descend into the concrete shafts, prepare your close-quarters weaponry for subterranean threats.

Finding and Interacting with the Valve

Once inside the tunnel network, you do not need to wander far to locate the target mechanism. The required valve wheel is situated nearby, tucked beneath the concrete ramp pathways along the outer wall. Look for a distinct bright yellow pipe fitted with a red steering wheel valve.

Approach the pipe and hold the interaction input to turn the valve and switch the water line. Successfully interacting with this object completes the primary task immediately without requiring additional items. Players can check their active objective log to verify that the quest progress has saved.

Surviving Hazards and Extraction Strategies

The darkness of the Spaceport tunnels conceals aggressive enemies, including explosive Ticks and automated defense turrets. Maintaining steady awareness and using light sources sparingly will prevent unexpected ambushes. If you need extra gear, check out the Switching the Supply walkthrough resources for detailed loot locations.

One major advantage of this assignment is that extraction is completely optional for mission validation. As soon as the valve interaction finishes, your quest credit is secured even if your character falls in combat afterward. However, successfully extracting back to Speranza allows you to keep any extra materials gathered from the tunnel crates.

Claiming Quest Rewards from Celeste

After returning to the home base, report directly to Celeste to turn in the completed assignment. For your efforts in securing the new water route, she grants valuable crafting materials including Synthesized Fuel along with special keycards. These rewards provide vital resources for upgrading gear and preparing for high-tier raiding drops.

Completing this mission also unlocks subsequent story beats and trade options within the settlement. Mastering efficient routes through the Spaceport tunnels will serve you well in future operations across the surface.
