A Toxic Trail
We've got clean water again, but we can't risk people falling ill if the saboteurs return. We need to root them out once and for all.
Key Takeaways
- Given by Shani and takes place in Dam Battlegrounds.
- Includes 4 objectives focused on exploration, delivery, photography.
- Rewards 4 items upon completion.
- Part of a multi-step quest chain from Shani. Both a prerequisite quest and follow-up quests exist.
Objectives
All objectives carry over between raids. You do not need to complete everything in a single run.
Walkthrough Tips
Search objectives have specific interaction zones you need to reach. Use your compass marker to navigate to the general area, then look for the highlighted interaction point. Some search areas may have multiple valid spots.
Photography objectives require using the camera item from your inventory. Point at the target from within range and snap the photo. Multiple angles may be needed if the first attempt doesn't register.
Delivery objectives require you to carry items to a destination. Dying while carrying quest items won't lose them permanently, but you'll need to retrieve them from the quest giver again.
With multiple objectives spread across the map, consider tackling them over two or more raids rather than rushing through everything at once. Prioritize objectives that are close together.
This quest is part of a chain. Completing the previous quest(s) in the series is required before this one becomes available from the trader.
Recommended Loadout
Light Weapon (Pistol or SMG)
Exploration quests have less direct combat but you still need something for self-defense. A lightweight weapon keeps your mobility high.
Healing Items (Bandages or Medkits)
Delivery runs mean traveling across the map while carrying quest items. Healing supplies keep you alive during the long trek without needing to divert for supplies.
Camera (Required)
Photography objectives require the camera item from your inventory. Make sure it is equipped before deploying to the map.
Zipline
Ziplines speed up navigation between objectives spread across the map. Place them on high points to create shortcuts for return trips.

Take a photo of the barrel truck
Open your inventory and equip the camera. Approach the target until the photo prompt appears, then snap the shot. If it does not register, try adjusting your angle or moving closer. The camera has a limited range.

Map: Dam Battlegrounds
A massive hydroelectric dam complex and surrounding military installations. The dam structure itself creates dramatic elevation differences, with control rooms, staff areas, and maintenance tunnels providing interior objectives. ARC concentration is high, and the open dam top is a kill zone.
Stick to interior routes when possible. The dam top offers no cover from aerial threats. Staff rooms and control towers often require keys, so check surrounding areas for key spawns before heading to locked objectives.
