Switching The Supply is a Celeste quest in ARC Raiders. It takes you into the Spaceport tunnels, where your job is to find and turn a valve that reroutes the water supply. The quest is short, but many players waste time because they use the wrong tunnel entrance or keep searching underground longer than they need to.
The easiest way to finish it is simple: use the best tunnel entrance, follow the shortest route underground, turn the valve, and leave once the quest is done. Most current guides also agree on an important point: the valve interaction is the key step, and extraction is generally not required for the quest itself to count.

Why this quest feels harder than it is
This is not a big puzzle quest. It is not a long combat mission either. The real problem is that players often make it bigger than it is.
Most failed runs happen for simple reasons:
- they enter the tunnels from a slower side
- they start checking the wrong tunnel branches
- they are unsure if the valve is the final step
- they think they still need extraction for the quest to count
Once you know the right entrance and keep the route tight, the quest becomes much easier. PC Gamer’s current guide especially highlights that the best entrance choice is what saves the most time here.
Helpful ways to clear quest routes faster without wasting time:
Best tunnel entrance for Switching The Supply
The most useful route advice in the current SERP is to enter the tunnels from the side southwest of the Launch Towers. That entrance is commonly described as the better choice because it gives a shorter and cleaner route to the valve than other tunnel entries.
That matters a lot. If you start from the wrong side, the quest can feel slow and confusing for no good reason. If you start from the better entrance, the whole run feels more controlled.
Why this entrance works better:
- it cuts down extra tunnel wandering
- it gets you to the valve faster
- it can reduce risk because you spend less time underground
If your main goal is just to clear quest bottlenecks and keep moving, that same low-waste approach is also why broader ARC Raiders progression help fits better than trying to turn this into a full loot run.
Fastest route to the valve
Enter from the correct side
Start with the recommended entrance near the southwest side of the Launch Towers area. Once you commit to that route, do not treat the tunnels like a free-search zone. This quest is much shorter than it first feels, and random exploration is what usually makes it frustrating.
Stay on the shortest underground path
The best mindset here is to stay focused on the objective and move with purpose. Do not turn the run into a farming trip. Do not stop to overcheck every branch unless the route truly stops making sense.
A simple way to think about it is:
- get in
- stay on the cleaner path
- find the valve
- interact and move on
That is the route logic most players actually need.
Find and turn the valve
The valve is the key interaction for the quest. Reaching the correct area is not enough by itself. The quest depends on the actual valve interaction registering properly. Current guide coverage treats this as the main completion trigger.
If you reach the right underground area and still feel unsure, stop looking for extra quest steps and focus on confirming the valve itself. That is the real target.
Does turning the valve complete the quest?
In practical terms, yes. The valve interaction is the step that matters most, and current guide coverage indicates the quest generally completes once that interaction registers. Game Rezone also frames the quest as completing immediately after interacting with the valve.
Important:
If the valve interaction registers correctly, you usually do not need another hidden underground objective before the quest counts. The biggest mistake here is assuming there must be one more step after the valve when there usually is not.
Do you need to extract after Switching The Supply?
Usually, no. Current guide coverage says extraction is generally not required for the quest itself to count as complete.
That said, quest completion and run safety are not the same thing.
- the quest usually counts after the valve interaction
- extracting afterward can still be the smart move if the area is active
So if your question is, “Do I need to extract to finish Switching The Supply?” the answer is usually no. If your question is, “Should I still leave safely if I can?” then yes, that is still the safer play.
If you are trying to keep overall account progress moving after small quest bottlenecks like this one, ARC Raiders leveling support is the only other natural progression fit that makes sense here without pulling the article away from user intent.
What usually goes wrong
Most problems with this quest come from one of these:
- Wrong entrance: starting from the wrong tunnel side makes the route slower and more confusing.
- Too much searching underground: the quest is shorter than it feels, so wide exploration usually wastes time.
- Missing the valve interaction: reaching the area is not enough if the valve itself is not used.
- Extraction confusion: many players think they failed the quest because they did not extract, even when the quest already counted.
If something feels off, go back to the basics: right entrance, short route, valve interaction. That solves most of the confusion.

Quick answers for Switching The Supply
Who gives Switching The Supply in ARC Raiders?
Celeste gives the quest, and the ARC Raiders Wiki places it after Source Of The Contamination.
Where does Switching The Supply happen?
It happens in the Spaceport tunnels. The key objective is underground, not out in the wider map.
What is the best entrance for Switching The Supply?
The strongest current route advice points to the entrance southwest of the Launch Towers, because it gives a shorter and cleaner path to the valve.
Do you need to extract after turning the valve?
Usually, no. The quest generally counts once the valve interaction is done, although extracting afterward may still be the safer move for your run.
Final tip
Switching The Supply is easier when you stop treating it like a big tunnel mission. It is really a short route problem.
Use the better entrance. Stay focused underground. Turn the valve. Once that is done, the hard part is over.
