The Stench of Corruption is a narrative-driven quest in ARC Raiders that deepens the mystery surrounding compromised infrastructure and internal sabotage. Introduced with the Cold Snap update, this mission is assigned by Shani and continues the investigation into polluted systems beneath the Spaceport. Unlike many other quests, this one demands precision, route knowledge, and survival discipline—because every objective must be completed in a single run.

Failing or getting eliminated at any point resets all progress, making preparation and awareness essential. Below is a full walkthrough designed to help you complete The Stench of Corruption efficiently and safely.

Quest Overview and Key Conditions

Before deploying, it’s critical to understand how this quest works.

Objectives (must be completed in one raid):

1. Reach the southwest lobby of the Departure Building

2. Locate the staff locker room

3. Search for clues identifying the saboteur

4. Reach the tunnels beneath the Spaceport

5. Use a key on any Flushing Terminal

There are no checkpoints. Even if you previously picked up the required key, it will not carry over if you fail the run.

Preparation Tips Before You Deploy

Because this quest forces you to traverse both a high-traffic building and underground tunnels, preparation matters more than firepower.

Recommended approach:

• Use a balanced loadout (not free-tier, but not high-value either)

• Bring healing and stamina items

• Avoid unnecessary PvP encounters

• Plan a clean route from building to tunnels

Speed and awareness are more important than combat success.

Step 1: Reach the Southwest Lobby of the Departure Building

Select the Spaceport map when deploying. Your first destination is the Departure Building, located on the western side of the map.

Landmark tips:

• West of the main Spaceport area

• Left of the Launch Towers

• Below the Arrival Building

The Departure Building is a known high-loot zone, which means it often attracts both Raiders and ARC patrols. Once inside, navigate toward the southwest lobby area. You’ll know you’ve reached the correct section when the objective updates automatically.

Step 2: Find the Staff Locker Room

With the lobby objective complete, your next task is to locate the staff locker room.

How to find it:

• Move to the lower floor of the Departure Building

• Look for staircases leading downward

• Watch for a blue wall sign labeled “Staff Room”

Inside, you’ll see rows of orange lockers, making this room visually distinct. Entering the correct room will immediately update your quest objective.

Step 3: Search for Clues of the Saboteur

This step is quick but easy to overlook if you rush.

Inside the locker room:

• Go to the back of the room

• Look for a clothing rack positioned against the wall

• Interact with it to investigate

This interaction reveals the clue you need and rewards you with the Flushing Terminal Key. This key is required later in the quest, but note that it does not need to be secured—it only matters during this single run.

Once obtained, the objective updates, sending you toward the underground tunnels.

Step 4: Reach the Tunnels Below the Spaceport

Exit the Departure Building and head toward the tunnel access point.

Correct route:

• Move outside toward the southeast side of the Departure Building

• Look for a ground opening southwest of the Launch Towers

• Drop down to enter the underground tunnel network

Once you enter the tunnels, the quest will confirm progress and update your final objective.

Be cautious here—tunnels are narrow, echo-heavy, and commonly patrolled.

Step 5: Use the Key on a Flushing Terminal

Your final task is to locate and interact with a Flushing Terminal.

From the most common tunnel entrance:

• Head northwest through the tunnels

• Stick close to the left-hand side

• Look for an interactable console mounted along the wall

When you reach the Flushing Terminal, use the key you obtained earlier to override the bypass protocol. This interaction completes The Stench of Corruption quest instantly.

At this point, survival no longer matters—you can extract safely or leave the raid knowing the quest is finished.

Rewards and Why This Quest Matters

One of the standout rewards for The Stench of Corruption is the Warden Outfit, a cosmetic that reflects your progress through Shani’s investigation chain. Beyond the outfit, this quest also unlocks further narrative context and future objectives tied to Spaceport infrastructure and internal corruption.

Having Trouble?

Because The Stench of Corruption must be completed in a single attempt, many players struggle with repeated resets due to PvP encounters or unlucky ARC spawns. This is where ARC Raiders Boosting at GladiatorBoost becomes a valuable option. With experienced players handling high-risk routes and objective timing, you can secure difficult quests like this one without wasting hours on failed runs. GladiatorBoost is especially helpful for completion-focused players who want progress without constant gear loss or frustration.

Final Tips for a Successful Run

• Avoid looting unless necessary—time increases risk

• Use audio cues heavily in the tunnels

• Don’t linger in the Departure Building

• If engaged, disengage and reposition rather than commit

The Stench of Corruption is less about combat dominance and more about controlled execution. With a clear route and calm decision-making, it becomes a manageable—and rewarding—mission.
