    Overview

    This guide walks you through the steps to complete "The Stench of Corruption" quest, which requires you to navigate the Spaceport map, find a specific key, and use it in the underground tunnels.

    Step 1: Reach the Departure Building

    Your first objective is to reach the southwest lobby of the Departure Building. This building is a large, red structure on the map.

    • Set a waypoint to the Departure Building on your map.
    • Travel to the Departure Building. Consider doing this during a normal raid rather than a Cold Snap raid as you'll be covering a significant distance.

    Step 2: Find the Staff Locker Room

    Once you arrive at the Departure Building, you'll need to enter it and locate the staff locker room.

    • Head towards the back side of the Departure Building. There are multiple entrances here.
    • Enter through one of the openings in the back of the building.
    • Inside, navigate towards the northwest side of this back area.


    • Locate a small door under a staircase that leads into the staff locker room.



    Step 3: Obtain the Flushing Terminal Key

    The key required for the quest's next step is found within the staff locker room.

    • Search the locker room for any clues. There will be various loot items here.



    • Find the white hazmat suits hanging on a rack in the center of the room. Interact with them to drop the Flushing Terminal Key.



    Step 4: Access the Tunnels and Use the Key

    With the Flushing Terminal Key in hand, your final task is to reach the underground tunnels and use the key at a specific terminal.



    • Head towards the underground tunnels. You can use an entrance near the Launch Towers.
    • Once inside the tunnels, proceed towards the north-west side.
    • Locate a control room with a terminal.
    • Interact with the terminal using your Flushing Terminal Key to override the bypass process. This will complete the quest.

    Quest Completion

    After successfully using the key at the terminal, the quest will be marked as complete, and you can claim your rewards.
