The ARC Raiders Toxic Trail mission is an investigation-focused quest that sends players into the swamp near the Water Treatment Control building on Dam Battlegrounds. Before heading out, players looking to strengthen their crafting options may choose to buy ARC Raiders BluePrints, but the quest itself mainly rewards careful exploration rather than heavy combat. The mission follows the contamination storyline and asks you to trace a toxic barrel back to the vehicle responsible for transporting it.

Understand the Quest Before Entering

A Toxic Trail is given by Shani after the appropriate earlier quest progression. Its four main objectives are to return to the water intake, search the swamp for the barrel's origin, photograph the barrel truck, and search that truck for evidence about the saboteur.

Knowing these objectives in advance is useful because the quest does not require you to fight through a large facility or complete a complicated puzzle. Instead, most of the challenge comes from finding the correct points of interest while remaining alert in an extraction shooter environment.

For that reason, consider bringing a practical loadout rather than carrying your most valuable equipment. You want enough supplies to handle unexpected encounters, but the mission does not demand a specialized combat build.

Find the Water Intake

Your first destination is the water intake below the Water Treatment Control building. This area can be identified around the contaminated water near the structure. The quest is designed as a continuation of the earlier contamination investigation, so returning to the location should feel familiar if you completed the previous mission.

Approach the contaminated barrel and stay close enough for the quest interaction to trigger. You do not need to spend a long time searching the entire building. Once the objective updates, your attention should shift toward the swamp.

Locate the Truck in the Swamp

The second objective is probably the easiest place to lose time. The game tells you to search the swamp for traces of the barrel's origin, but the wording does not immediately identify the exact destination.

The important landmark is a partially submerged truck carrying toxic barrels. From the water intake, travel through the swamp while watching the water and nearby open areas. The truck is not extremely far away, but vegetation can make it easy to overlook.

Avoid sprinting blindly through the area. The swamp has limited visibility and can leave you exposed to players who are watching common routes. Pause occasionally, listen for movement, and check your surroundings before approaching the vehicle.

Complete Both Truck Objectives

When you reach the truck, you need to photograph it and then search it for clues. The photo interaction is straightforward and advances the mission immediately.

After taking the picture, investigate the truck itself. This final interaction provides evidence concerning the saboteur and can also give you the Spaceport Warehouse Key. The key is particularly useful because it connects to future Spaceport activity, so protecting it should become a priority.

Extract or Continue Looting

Once the truck investigation is complete, the quest objectives are finished. At this point, you have a choice. You can leave the area immediately and secure your progress, or continue exploring Dam Battlegrounds for additional resources.

For players primarily interested in completing the quest, extraction is usually the sensible option. The mission does not require an extended stay after the investigation, and losing a useful key because of an unnecessary fight can be frustrating.

The listed quest rewards include one Tactical Mk. 2, three Ziplines, three Pulse Mines, and three Gas Mines.

A Toxic Trail is therefore a good example of how ARC Raiders rewards players who understand positioning instead of simply relying on firepower. Learn the water intake location, find the barrel truck, complete both interactions, and leave before unnecessary danger catches up with you. Keeping useful ARC Raiders BluePrints in your progression plan can also help you prepare for the more demanding missions that follow.
