Fortunately, the next objective doesn't require a long trek. From the drain, head west through the swamp. After a short walk, you'll come across a truck partially submerged in the murky water. It's positioned out in the open and is difficult to ARC Raiders Coins miss once you're close.

This truck is a critical piece of evidence in the investigation. Approach it and interact with the on-screen prompt to take a photograph. This confirms the vehicle's connection to the contaminated barrel and advances the quest to its final step.

Searching the Truck for Clues

After photographing the truck, your objective updates again, instructing you to search it for more information about who sabotaged the water supply. Interact with the truck's door to investigate further.

Inside, you'll discover a Spaceport Warehouse Key. ARCR Items provides confirmation that the contamination originated from Spaceport operations and ties the sabotage to a larger network rather than a random incident.

Once you pick up the key, make sure to place it in your safe pocket if you have one available. While the key is not required for future quests, it can unlock valuable loot during later Spaceport runs, making it a worthwhile item to keep.

Extracting Safely from the Swamp

With the Spaceport Warehouse Key secured, A Toxic Trail is effectively complete. At this point, your best option is to extract via the Central Swamp Lift, which is conveniently located nearby.

That said, be cautious. Extraction points in swamp areas are often prime ambush locations, and the Central Swamp Lift is no exception. Before initiating extraction, take a moment to scan your surroundings, check sightlines, and listen for enemy movement. Keeping your weapon ready could mean the difference between a successful extraction and losing your newly acquired key.

If everything goes smoothly, extract and return to Speranza to turn in the quest.

Quest Rewards and What Comes Next

Upon completing A Toxic Trail and reporting back, you'll unlock the next quest in the storyline: The Stench of Corruption. This follow-up continues the investigation into the poisoned water supply and is required if you want to earn the Warden outfit, one of the standout cosmetic rewards tied to this questline.

While A Toxic Trail is relatively short, it plays an important role in advancing the narrative and setting up future objectives. It also rewards attentive exploration, encouraging players to revisit earlier locations and re-examine clues with fresh context.

Final Tips for Completing A Toxic Trail

Extraction isn't required, but highly recommended if you want to keep the Spaceport Warehouse Key.

You don't need to interact with the barrel-just standing in the contaminated water progresses the quest.

The truck is nearby, so avoid unnecessary combat or risky detours.

Always check the Central Swamp Lift for campers before extracting ARCR Items.

A Toxic Trail may not be the longest quest in Arc Raiders, but it delivers meaningful story progression and a useful reward if you play it smart. Stay alert, follow the clues, and you'll be one step closer to uncovering the truth behind the water contamination.

If you want to climb the Arc Raiders leaderboard or simply secure strong weekly rewards, mastering the trial system is essential. Trials are among the most competitive activities in the game-high pressure, heavily optimized, and demanding precise routing and teamwork. This guide breaks down the core rules, the best maps, spawn systems, and high-level strategies used by top players to ARCR Coins consistently secure elite scores.
