You’d think fixing the water in Speranza would buy you a bit of peace, but Shani’s not wired that way. “A Toxic Trail” starts with that nagging question: who hauled those barrels in, and why risk the whole settlement? If you’re stocking up on gear or even browsing ARC Raiders Coins between runs, this is one of those quests that’s worth scheduling in, because it sets up bigger trouble and hands you a key you really don’t want to lose.
Back to the intake, but don’t overthink it
Queue into the Dam Battlegrounds and head straight for the water intake under the Water Treatment Control building. It feels like a repeat trip, yeah, but the trigger is different enough to trip people up. When you reach the spill area where the barrel was dumped, you don’t need to “use” anything. No prompt, no button. Just get close to the intake and hang there a second until the quest updates. If you’re mashing interact and nothing’s happening, that’s why. Once it pops, your marker shifts and you’re on the actual trail.
Follow the trail west and take the photo
From the intake, push west through the shallow swamp. It’s not a long trek, but it’s the kind of ground where you’re exposed and distracted, which is a bad combo if another squad is sniffing around. You’re hunting a wrecked truck, half swallowed by mud. You’ll spot it by the load: yellow barrels stacked in the back like someone was mid-delivery and panicked. Walk up until the camera prompt appears, then take the photo. That’s your proof, and it’s the moment the mission starts feeling more like an investigation than a loot sprint.
Grab the key and protect it like it’s contraband
After the picture, don’t wander off. Go to the truck’s cabin, right by the driver’s door, and search it. This is the step that matters. The truck drops a Spaceport Warehouse Key, and it’s not just flavour—this is access to a real lock on the Spaceport map. The quest itself completes as soon as you loot the cabin, so technically you can get wiped and still tick the objective. But the key won’t come home with you unless you extract. If you’ve got a safe pocket augment slot free, stash it immediately. People lose this key because they treat it like normal loot, then get jumped on the way out.
Cash in the rewards and plan the next run
Once you’re back in Speranza, Shani pays out with a Tactical MK.2 augment plus Ziplines, Pulse Mines, and Gas Mines, and the utility is the real win—Ziplines change how you rotate and escape when a fight goes sideways. If you’re trying to keep momentum without wasting time re-gearing, it helps to have a reliable source for game currency and items; that’s where RSVSR fits in, so you can focus on the Spaceport follow-up instead of grinding the same loops again.Welcome to RSVSR, where ARC Raiders tips feel like they’re from a mate, not a manual.
