Arc Raiders – A Toxic Trail Full Quest Guide

Arc Raiders has a ton of quests to keep you busy while you loot and scavenge your way throughout an apocalyptic Earth. One of those quests, A Toxic Trail, has you investigating who contaminated the water supply. Here’s a full guide to A Toxic Trail.

A Toxic Trail Full Quest Guide

The first step to completing A Toxic Trail in Arc Raiders is to head back to the drain where you previously found the barrel for the Source of the Contamination quest. This barrel can be found outside the Water Treatment Center on the Dam Battlegrounds map. Walking around the area where the barrel is located will trigger the next step of the quest.

The next step of the quest will ask you to find where the barrel came from. If you walk west just a bit, you’ll find a truck in the swamp water, which will have a bunch of other barrels in it, indicating that’s where the barrel came from. As you approach the truck, interact with the prompt that shows up to take a photo of it. You’ll also receive your final task to search the trucks for clues.

As a side note, when you interact with the door of the truck, you’ll find a Spaceport Warehouse Key. Pick it up and place it in your safe pocket, as it can come in handy for finding good loot next time you’re in Spaceport.

This will be the end of A Toxic Trail, and you can extract at the nearby Central Swamp Lift. When you return to Speranza and turn this quest in, there will be a follow-up quest called The Stench of Corruption, which you’ll need to complete to earn the Warden outfit. You don’t necessarily need to extract from the map to complete A Toxic Trail, but it’s not a bad idea to do so, to save any items you find during the quest, like the Spaceport Warehouse Key.
