The ARC Raiders Toxic Trail quest is now live in the game with the launch of the Cold Snap update, and you can complete it to earn some cool rewards.
You can begin the A Toxic Trail after finishing the older quests and by accepting it from Shani. It’s part of the latest update, and requires you to find the source of a toxic barrel in the Dam Battlegrounds map. This guide will help you complete all the steps required to finish the quest.
ARC Raiders A Toxic Trail quest walkthrough
A Toxic Trail quest can be broken down into the following parts.
- Return to the Water Intake below the Water Treatment Control building
- Search the swamp for traces of the barrel’s origins
- Take a photo of the barrel truck
- Search the truck for clues about the saboteur’s identity
To start the quest, you’ll want to head to the location marked on the screenshot below. It’s towards the western boundary of the Water Treatment Control building on the Dam Battlegrounds map. You’ll find a half-sunk barrel. Go close to the barrel, and the quest will update.

The next task is to trace the origin of the barrel. The origin, incidentally, isn’t too far from the location of the barrel. Head straight along the water body, and then turn left. Go straight, and you’ll come across a truck whose wheels are sunk in the water.

Interact with the truck and click a photo. Then, complete the investigation to finish the questline. It’s a straightforward task to complete, and you’ll get plenty of resources to add to your inventory. Incidentally, you’ll also get a Spaceport key that will be required in another quest.
You can also find Candleberries near the spot of this quest, which is required to complete the Flickering Flames project. The project will be live throughout the remainder of December and continue until January as part of the Cold Snap update.
