The sprawling corridors of Talos I are filled with mysteries, but few locations have frustrated players as much as the locked I.T. Supply Closet in the main Lobby. Positioned within the I.T. Security office, this small room remains a tantalizing enigma for much of the game. Most players spend hours scouring the nearby desks, hacking into every terminal, and checking the pockets of every Mimic-infested corpse in the vicinity, only to find no mention of a keycard.

The reality of the I.T. Supply Closet is tied to the complex, branching narrative of Arkane Studios' immersive sim. It is not a standard locked door meant to be opened through typical exploration; rather, it is a reward for a very specific (and often violent) playstyle, or a target for those willing to exploit the game's physics engine. Understanding how to get inside requires a deep dive into the station’s late-game mechanics and the hidden agendas of its inhabitants.

Finding the I.T. Supply Closet on Talos I

Before attempting to breach the door, you must first navigate to the correct sector. The I.T. Security office is located on Level 2 of the Talos I Lobby. If you are standing in the center of the Lobby near the shuttle bay entrance, you will need to head toward the area adjacent to the Trauma Center.

The I.T. Security department is a hub of monitors and server racks. While the main security room can be accessed through hacking (Hacking II or higher) or by finding a maintenance vent located near the ceiling in the hallway, the supply closet situated inside this office is a different story. The door to the closet itself requires a specific "I.T. Supply Closet Keycard," and unlike the key for the main security door, this one is notably absent from the immediate environment.

The Legitimate Path: The Showing Initiative Mission

For players committed to the "intended" way of playing Prey, there is only one path to obtaining the I.T. Supply Closet keycard, and it involves a dark turn in your journey. This keycard is tied to a mission called "Showing Initiative," which only triggers under very specific circumstances during the late-game arrival of Commander Walther Dahl.

Triggering the Genocide Run

To receive the "Showing Initiative" mission, you must be on what the community calls a "Genocide Run." This means you must have killed almost every human survivor on Talos I before Dahl arrives on the station. If you have been playing as a savior, rescuing the staff in the Cargo Bay or the Greenhouse, this mission will remain locked to you.

Dahl is sent by the TranStar Board of Directors to "clean up" the station, which includes eliminating any witnesses. If you have already done most of the work for him, Dahl will contact you and offer a partnership. He views your efficiency as an asset and tasks you with hunting down the final four survivors hiding in the I.T. Supply Closet.

Completing Showing Initiative

Once the mission is active, Dahl informs you that a group of employees has barricaded themselves inside the I.T. department. These survivors—Steve Folson, Richard Coveney, Harley Grainger, and others—are the ones who actually hold the keycard.

When you reach the I.T. Security room during this mission, the closet door will either be unlocked or one of the targets will be carrying the keycard. Eliminating them completes the mission and finally grants you access to the contents of the room. It is a grim irony that the only "official" way to see what is inside is to become the very monster the station's security protocols were designed to stop.

The Glitch Method: Using the GLOO Cannon and Recycler Charge

If you are playing a "No Needles" run or simply don't want to murder the entire crew, you can turn to the game's creative physics. Prey is famous for its emergent gameplay, where the interaction of different tools can lead to unintended results. The "GLOO and Recycler" trick was, for a long time, the primary way players accessed the I.T. Supply Closet early.

Step-by-Step Glitch Guide

While Arkane has released several patches for Prey, many players still report success with physics-based clipping. The logic involves overwhelming the door's collision box until the game "pushes" the player character through the geometry.

  1. Preparation: You will need a fully loaded GLOO Cannon and at least one Recycler Charge.
  2. Covering the Door: Aim your GLOO Cannon at the seam of the I.T. Supply Closet door. You want to create a massive, dense cluster of GLOO foam that completely covers the door handle and the center of the door frame.
  3. The Recycler Charge: Throw a Recycler Charge directly into the center of the GLOO mass.
  4. The Timing: As the Recycler Charge detonates, it begins to suck in the GLOO foam and any nearby objects. During this brief window where the physics engine is calculating the destruction of the GLOO, the door’s collision detection often falters.
  5. The Breach: Sprint and crouch toward the door as the Recycler Charge activates. If done correctly, you will "clip" through the door and find yourself inside the closet.

Note: This method is temperamental. It may take several tries, and with the latest Steam or console updates, the collision boxes have been tightened. However, for those stuck in the mid-game without a way to trigger Dahl’s mission, this remains the most viable "exploit" path.

Alternative Entry: The I.T. Security Ceiling Access

It is important to distinguish between the I.T. Security Room and the I.T. Supply Closet. Many players confuse the two. If you are simply trying to get into the I.T. department to access the workstations or find the tracking software, you do not need the supply closet keycard.

There is a maintenance tunnel located above the Lobby. By heading to the second floor and looking for the glass floor panels in the offices above the I.T. sector, you can actually shoot out the glass or find a vent that allows you to drop down into the main I.T. Security area. This bypasses the need for the Hacking skill entirely. Once inside the main office, however, the Supply Closet remains a separate, locked entity within the room.

What is Inside the I.T. Supply Closet?

The fascination with this room isn't just about the loot; it's about the mystery. But for those who manage to breach the door, what actually awaits?

The Developer Easter Egg

The I.T. Supply Closet is primarily a tribute to the team at Arkane Studios. Inside, you will find several tracking bracelets. If you check the names associated with these bracelets, you will recognize them as the developers who built the game.

The "survivors" listed in this room (when tracked via a Security Station) are the digital avatars of the creators. Finding their ID bracelets is a meta-commentary on the people who "built" the systems of Talos I.

Resources and Loot

Beyond the Easter eggs, the room functions as a standard supply cache. Depending on your difficulty level and RNG (Random Number Generation), you can typically find:

  • Neuromods: Essential for upgrading your Typhon or human abilities.
  • Recycler Charges: Useful for clearing paths or manufacturing materials.
  • Weapon Upgrade Kits: To boost the power of your Shotgun or Q-Beam.
  • Rare Fabrication Plans: Occasionally, higher-tier ammo or suit repair plans can spawn here.

While the loot is valuable, it is rarely "game-changing" by the time you are powerful enough (or far enough in the story) to access it. The true reward is the satisfaction of finally clearing that locked icon from your map.

The Design Philosophy of the Locked Closet

Arkane Studios often includes "impossible" rooms in their games. The I.T. Supply Closet serves a specific purpose in the "Immersive Sim" genre. It rewards curiosity and forces the player to accept that not every door is meant to be opened by everyone.

In a standard RPG, every lock has a key hidden nearby. In Prey, the world exists independently of the player. The people in the I.T. department barricaded themselves in for a reason, and if you play as a "good" Morgan Yu, you simply never have a reason to force them out. It’s a brilliant piece of environmental storytelling that prioritizes the internal logic of the world over the completionist tendencies of the player.

Frequently Asked Questions

Can I find the I.T. Supply Closet keycard in the Trauma Center?

No. While there are many notes in the Trauma Center discussing the security of the Lobby, the actual keycard for the I.T. Supply Closet is not found there. The Trauma Center contains the keycard for the Quarantine zone and Dr. DeVries' office, but nothing for the I.T. department.

Is the GLOO Cannon glitch patched?

In the most recent versions of Prey (including the Digital Deluxe and Mooncrash updates), the developers improved the collision physics to prevent easy clipping. While it is significantly harder to perform than it was at launch, it is not entirely impossible due to how the Recycler Charge interacts with GLOO. However, it is no longer a reliable strategy for most players.

What happens if I kill the people inside during the "Showing Initiative" mission?

If you are on the mission for Dahl, killing them is the objective. You will be able to loot their bodies for the keycard (if you haven't opened the door yet) and other personal items. Dahl will reward you with resources and further support for your "clean-up" of the station.

Is there a vent leading directly into the closet?

No. There is a vent leading into the I.T. Security Room, but the Supply Closet is a sealed room within that space. There are no crawlspaces or maintenance shafts that bypass the closet door itself.

Summary of Access Methods

To recap, if you are looking to enter the I.T. Supply Closet in Prey, you have three distinct options:

  1. The Moral Choice: Accept that the door remains locked. In a standard "heroic" playthrough, the survivors inside remain safe, and you miss out on a few Neuromods and a developer Easter egg.
  2. The Ruthless Choice: Commit to a Genocide Run. Kill the crew, wait for Dahl to arrive in the late game, and accept the "Showing Initiative" mission to get the keycard legitimately.
  3. The Engineer's Choice: Use the GLOO Cannon and Recycler Charge to attempt a physics clip. This requires patience and a bit of luck with the game's engine.

The I.T. Supply Closet stands as a testament to the depth of Prey. Whether you enter it through blood or through bugs, it remains one of the most talked-about secrets on Talos I, proving that even a simple closet can become a legendary part of gaming lore.
