If you have been stuck on the Worth Your Salt Arc Raiders quest, you are not alone. Introduced with the Shrouded Sky update, this Spaceport mission looks simple on paper — grab a battery, charge it, drop it off — but the reality is that only one player per raid can complete the final delivery step. That competitive lock-out mechanic has frustrated more Raiders than any of the actual ARC machines in the building.
This guide covers every step of the Worth Your Salt quest in Arc Raiders from start to finish: where to pick it up, the exact location of the Battery Prototype, how to use the Industrial Recharger, where the drop-off point is, and — most importantly — how to make sure you beat other players to it.
What Is the Worth Your Salt Quest in Arc Raiders?
Worth Your Salt is a quest assigned by Celeste, the trader NPC based in Speranza. It becomes available after you have completed the Groundbreaking quest in her chain. Celeste’s briefing explains that electrical engineers at the Spaceport were apparently working on advanced salt-based batteries before everything fell apart — and if you can recover a working prototype, Speranza might be able to prevent future power failures.
The quest is part of the Shrouded Sky update, which was added to Arc Raiders in early 2026. Completing Worth Your Salt unlocks a partial entry in the Project Heartwood Codex and flows into the next quest in Celeste’s line, On Deaf Ears.
It is a standalone, single-objective mission with no branching paths. The entire quest takes place within one building on one map — the Rocket Assembly on Spaceport. All five objectives must be completed in a single raid. You cannot split the steps across multiple runs.
Worth Your Salt Quest Objectives
The quest UI reveals objectives one at a time as you progress. Here is the full list in order:
- Go to the Rocket Assembly
- Search for the hidden Battery Prototype in a high place
- Bring the Battery Prototype to the Industrial Recharger
- Use the machinery to charge the battery
- Deliver the Charged Battery to the drop-off point in the corner
How to Start the Worth Your Salt Quest
Head to Speranza and speak to Celeste. If you have completed Groundbreaking, Worth Your Salt will be available as her next assignment. Accept the quest and then launch into a Spaceport raid.
This quest is only completable on the Spaceport map. Do not launch into Dam Battlegrounds, Buried City, or any other map — the Rocket Assembly building only exists on Spaceport.
Step-by-Step Walkthrough: Worth Your Salt in Arc Raiders
Step 1: Navigate to Rocket Assembly
Rocket Assembly is located in the northern section of the Spaceport map. It is the large warehouse-style building that borders the Fuel Control area and the East Container Yard to the northwest.
Enter through the north side of the building if you can. The northern entrance puts you closest to the quest area and helps you avoid unnecessary ARC encounters on the approach. The interior features distinctive red walkways — you will know you are in the right section when you see them.
Before committing to the quest steps, do a quick check: look at the drop-off container in the corner of the north section. If it already contains a battery, another Raider has beaten you to the delivery this round. In that case, it is best to extract early and try again next raid rather than waste time completing steps that cannot be finished.
Step 2: Find the Battery Prototype
Once inside the north section of Rocket Assembly, your objective is to locate the Battery Prototype. The quest clue says it is hidden “in a high place” — and it means it literally.
Go to the upper level of the north section by climbing the stairs. The Battery Prototype is located on an elevated shelf or platform on the upper floor. Interact with it to pick it up.
If you are having trouble pinpointing the exact shelf, look for the interaction prompt while moving along the upper walkway. The prototype is not hidden behind a locked door — it is accessible without any keys or additional steps.
Step 3: Bring the Battery Prototype to the Industrial Recharger
With the Battery Prototype in hand, locate the Industrial Recharger — the large charging machinery nearby on the same level or just below. The recharger is a prominent industrial unit and should be visible from your position once you have the battery.
Carry the prototype to the recharger and interact with it to begin the charging process.
Step 4: Charge the Battery
Use the Industrial Recharger’s machinery to charge the Battery Prototype. This is an interactive step — you will need to trigger the charging sequence. After a brief wait, the battery will be fully charged and ready for delivery.
This is also the step most commonly affected by the quest bug. Some players have reported that the recharger interaction does not complete correctly when another player has already interacted with it earlier in the same raid. If the machinery appears unresponsive, it is likely that someone else has already progressed the quest on this server instance. At that point, the best option is to cut your losses and extract — this is not something that can be fixed mid-raid.
Step 5: Deliver the Charged Battery to the Drop-Off Point
Take the Charged Battery to the drop-off container in the corner of the north section of Rocket Assembly. Interact with the container to deliver it and complete the quest.
This is the most contested step. Only the first Raider to place a charged battery in the drop-off container per raid can complete the delivery. If another player delivers before you, the container interaction will lock you out entirely. There is no workaround for this — it is either a known bug or an intentional competitive mechanic, and Embark Studios has not issued a definitive statement on which it is as of 2026.
How to Win the Race: Tips for Completing Worth Your Salt First
Given the competitive lock-out, speed is the determining factor in whether you complete Worth Your Salt in any given raid. Here are the practical steps that increase your chances.
Drop into the raid with a plan. Do not figure out where Rocket Assembly is after you spawn. Know the location before you land, set a direct route, and move immediately without looting side rooms on the way in.
Check the drop-off container first. As mentioned above, verify the container is empty when you first enter the building. If it already has a battery, you cannot finish the quest this round. Knowing this early saves you the full time investment of running the other steps.
Avoid unnecessary ARC fights on the approach. Rocket Assembly will have ARC patrols. Engaging every machine you encounter slows you down significantly. If an ARC robot is not blocking your path to the quest objectives, skip it. Stealth movement through the building is worth considering on higher-activity servers.
Be aware of other Raiders. Rocket Assembly is a high-traffic area during Shrouded Sky raids because of this quest. Expect PvP pressure — especially if you are carrying the Charged Battery toward the drop-off. Other players may not be after the quest at all and will still target you for the loot value of the battery and anything else you are carrying.
Know your extraction route before you deliver. Once you complete the drop-off, extract quickly. You have just spent time in a contested building and made noise doing it. If you are unsure how extraction works on Spaceport, our Arc Raiders extraction guide covers all available methods — Cargo Elevators, Metro Stations, and Raider Hatches — and when each makes the most sense based on your situation.
Worth Your Salt Quest Reward
Completing Worth Your Salt grants you one item: the Vita Spray Blueprint.
The Vita Spray is an Epic rarity healing item. The blueprint allows you to learn the crafting recipe, which requires the final level of the Medical Lab in your Workshop. If you already have the Vita Spray Blueprint unlocked from a previous source, the duplicate blueprint can be sold for 5,000 coins instead.
For a healing item of that rarity, it is a strong reward — particularly if you are building toward a support-oriented loadout. Healing items and survivability tools become significantly more important as you progress into harder content and contested maps, so having reliable access to the Vita Spray recipe is a meaningful long-term unlock.
Rocket Assembly: What Else Is Worth Doing Here
Even if you do not complete Worth Your Salt on a given run — whether because another player beat you to it or the bug triggered — the Rocket Assembly building is a strong loot area in its own right. It contains dense item spawns, ARC machine drops, and multiple routes that feed into the broader Spaceport layout.
The Spaceport is also one of the maps where ARC machines like the Shredder appear, particularly in tighter indoor spaces. If you encounter a Shredder while running through Rocket Assembly or the surrounding areas, the key is to prioritize the thruster weak points and use cover to cycle through the shrapnel blast recovery loop. For a full breakdown of how to handle that fight, see our Arc Raiders Shredder guide.
If you are planning a longer run on Spaceport and want to exit efficiently after completing Worth Your Salt, Raider Hatches are the quieter extraction option compared to a Cargo Elevator, which broadcasts your location. Our Arc Raiders Raider Hatch Key guide covers all hatch locations and how to get keys.

Final Thoughts
Worth Your Salt is one of the more memorable Arc Raiders quests — not because it is mechanically complex, but because the competitive delivery mechanic turns a simple fetch quest into a race with real pressure. Once you understand the layout of Rocket Assembly, check the drop-off container first, and move efficiently, it becomes very completable. The Vita Spray Blueprint is a genuine reward worth the effort, especially if you are building out your Workshop’s Medical Lab.
