The "Worth Your Salt" quest in ARC Raiders starts after Celeste mentions some old notes about a salt-based battery prototype built at the Spaceport. Your job is simple on paper: go into a Spaceport raid, find the prototype, charge it, and drop it off. In reality, because it's an extraction shooter, you have to do all of that in one life during a single raid. If you die, you're starting over. Since the objective is inside one of the busier points of interest, expect both ARCs and other players to show up ARC Raiders Coins.

When you load into Spaceport, head toward the Rocket Assembly building in the northeast section of the map. It's a big structure near the Launch Towers and easy to spot, which also means it's often contested. If you can, enter from the north side to avoid running straight into early fights. Once inside, move toward the northwest side of the building. There are catwalks, lockers, and a lot of machinery, so check corners carefully. It's a good spot for ambushes.

The Battery Prototype is on the second level along a red railing in the northeast section of the building. Look for a small crate near a row of red lockers. You'll need to climb the stairs or use the catwalk to reach it. Once you interact with it, you'll pick up the prototype, but you'll be carrying it with both hands. That slows you down a lot and leaves you unable to fight properly, so clear the area first if you can. Also, only one prototype spawns per raid instance, so if another squad grabs it first, you're out of luck for that round.

After picking it up, head toward the center of the Rocket Assembly room. You're looking for an Industrial Recharger, usually a red machine with a grey console attached. Interact with the console to insert the battery, then pull the lever to start charging it. The process takes a few seconds, and you're basically stuck there while it runs. Make sure someone is watching your back if you're in a squad. Once it finishes, the machine spits the battery back out, and you'll have to carry it again at the same slow pace.

The final step is delivering the charged battery to the drop-off container in the north corner of the room, typically near an exit door. Interact with the crate to deposit it, and the quest completes instantly. You don't need to extract with the item afterward. Be aware that there's been a bug where if someone else completes the drop-off first, the container can glitch and become unusable. If that happens, your only option is to extract and try again in another raid.

Completing the quest rewards you with the Epic Vita Spray blueprint. It's a strong healing item you can craft later, or you can sell the blueprint if you already have it. It also progresses the Project Heartwood codex entry and helps with Celeste's trader line. The Vita Spray is especially useful in longer raids where you don't want to rely only on limited healing supplies.

For an easier run, bring a light loadout so you can move quickly and handle close-range fights inside Rocket Assembly. SMGs and shotguns work well because most engagements happen indoors. If you're solo, sometimes you can signal other players and cooperate briefly during the charging phase, but don't rely on it. Clear nearby ARCs before interacting with the recharger, and learn the layout on lower difficulty runs if possible cheap ARC Raiders Items.

"Worth Your Salt" is a good example of how ARC Raiders turns a simple objective into something tense. The steps are straightforward, but the risk of losing progress keeps the pressure high. If you move fast, clear smart, and don't get greedy, it's a manageable quest that gives you a useful reward and some extra lore along the way.
