Quick Answer
Enter the southwest lobby of the Departure Building, go to the lower-level staff locker room, and interact with the rack holding two hazmat suits to obtain the Flushing Terminal Key. Then leave toward the Launch Towers, drop into the tunnels through the collapsed ground opening or ladder structures, move west to the maintenance area and use a flashing Flushing Terminal. Finish every step in one run; extraction is not required.
How to Unlock The Stench of Corruption
Complete A Toxic Trail for Shani first. The Stench of Corruption directly follows the barrel-truck investigation and continues Shani's search for the person responsible for the contamination.
The Stench of Corruption Requirements
You need Spaceport access and A Toxic Trail completed, but you do not need to bring a quest item or survive an extraction after the final terminal.
- Complete every objective in the same raid.
- Do not expect the Flushing Terminal Key to carry a failed run forward.
- A free or cheap loadout is reasonable because the quest ends at the terminal.
- Head straight to the Departure Building instead of detouring for fights.
How to Reach the Southwest Lobby
The Departure Building is the large red structure near the middle of Spaceport, just west or south-west of the Launch Towers. Aim for the southwest side by the parking lot; entering that lobby advances the first objective.
This same building is used by Prescriptions of the Past, Medical Merchandise and On the Map, so you can stack objectives if those quests are active.
Where to Find the Staff Locker Room
The staff locker room is on the lower level beneath the southwest lobby.
- Enter through the southwest lobby by the parking lot.
- Move forward and take the path on the right.
- Use the door to the left of the staircase.
- Turn slightly right and go downstairs to the lower-level locker room.
The room is also a loot spot, so expect players who are there for gear rather than the quest.
Where to Find the Flushing Terminal Key
The Flushing Terminal Key comes from the rack holding two hazmat suits inside the staff locker room. Look along the right side of the room and interact with that rack.
Do not confuse this room with the separate exam-room area used by Medical Merchandise. The confirmation cue here is the lower-level staff locker room reached from the southwest lobby route.
How to Get Into the Spaceport Tunnels
Leave the Departure Building and head toward the Launch Towers, then enter the tunnel network through the collapsed ground opening or the nearby white ladder structures.
The same underground network appears in Switching the Supply and The Clean Dream. If you lose your bearings below ground, the tunnel map layer used for Switching the Supply is the fastest way to reorient.
Which Flushing Terminal to Use
Use a flashing Flushing Terminal in the western maintenance area of the tunnels, where the walkway is lined with computer banks. Follow the westward route until you see the active terminal prompt and use the key there.
The quest completes as soon as the terminal accepts the key, so you can continue looting or die afterward without losing quest completion; extraction is optional.
The Stench of Corruption Rewards
The Stench of Corruption rewards the Warden Outfit.
| Reward | Type | Note |
|---|---|---|
| Warden Outfit | Cosmetic | Base Warden cosmetic set reward. |
Groundbreaking and A Dead End award Warden colour variants, so those quests build on the outfit earned here.
What Comes After The Stench of Corruption
This quest closes the immediate Spaceport sabotage investigation by pointing Shani toward Speranza's own waste-disposal operation. After using the terminal, return to Speranza and check Shani's next available objective to continue the Cold Snap chain.
