PUBG Deston Secret Room Guide -- Complete Walkthrough (2026)

Deston is one of the most ambitious maps in PUBG: Battlegrounds, spanning a massive 8x8 km landscape that blends modern urban environments with natural terrain. The map features a sprawling downtown area filled with towering skyscrapers, the iconic Concert Hall venue, the Lodge resort area, and a massive hydroelectric dam that cuts through the landscape. What sets Deston apart from other PUBG maps is its verticality -- many buildings stretch dozens of floors high, and players can use ascenders to zip up the sides of skyscrapers for rapid repositioning. Hidden within these high-rise structures are some of the most lucrative loot locations in the entire game: Security Rooms. These locked rooms require a Security Keycard to access, and once opened, they reward players with top-tier weapons, Level 3 gear, and rare items that can turn the tide of any match. In this comprehensive guide, we cover everything you need to know about finding keycards, locating every secret room, and maximizing your loot on Deston.

What Are Deston Security Rooms?

Deston Security Rooms are specially designed locked areas found inside the map's skyscrapers and high-rise buildings. You can identify them by their distinctive glass-encased walls and reinforced steel doors -- they stand out clearly from normal rooms when you are exploring a building's interior. Unlike regular loot spawns scattered across the map, Security Rooms guarantee high-tier loot every time they are opened. The mechanic is straightforward: find a Security Keycard somewhere on the map, carry it to a Security Room door, and interact with the card reader panel to unlock it. Once inside, you will find a curated selection of the best gear available in PUBG: Battlegrounds. Each Security Room can only be opened once per match, so if you see an open door, another squad has already claimed the loot inside. The keycard is consumed upon use, meaning you need one keycard per room you want to unlock.

How to Find Security Keycards on Deston

Security Keycards on Deston spawn as ground loot in specific types of buildings across the map. The most reliable keycard spawn locations include the Concert Hall complex in the western part of the city, the Lodge resort buildings near the coast, the Riverbay residential area, and various commercial district offices scattered throughout downtown. Keycards appear as small, flat rectangular items on the ground or on tables and desks -- they have a subtle blue glow that makes them easier to spot in darker interiors. The spawn rate is not guaranteed at every location, so you may need to check multiple buildings before finding one. To maximize your chances, we recommend landing at the Concert Hall or Lodge early in the match, as these locations tend to have higher keycard spawn density and are slightly less contested than the downtown core. Always check reception desks, office cubicles, and countertops, as keycards tend to spawn on flat surfaces rather than on the floor. You can also find keycards by eliminating other players who have already picked one up -- the keycard will drop as part of their death crate loot.

All Deston Secret Room Locations

Deston's Secret Rooms are concentrated in the tallest buildings across the map, primarily in the downtown skyscraper district. The central business area features multiple high-rises with Security Rooms on their upper floors -- typically between the 10th and 20th stories. Look for buildings with working ascenders on the outside, as these often lead directly to floors containing Security Rooms. The Riverbay apartment complexes east of downtown also contain several Security Rooms tucked into their upper floors, and these tend to be less contested since many squads focus on the flashier skyscrapers. The Lodge area in the northern part of the map has Security Rooms in its larger multi-story resort buildings, making it an excellent early-game landing spot if the flight path is favorable. Additionally, some of the commercial buildings near the hydroelectric dam contain Security Rooms on their middle floors. Use our interactive map at the top of this page to see the exact pinpointed locations of every confirmed Security Room on Deston, complete with floor numbers and building identifiers to help you navigate quickly during a match.

Loot Table: What's Inside Deston Secret Rooms

Deston Security Rooms contain a curated pool of the rarest and most powerful items in PUBG: Battlegrounds. Each room spawns a randomized selection from the following loot table, typically providing 4-6 items per room:

• Level 3 Helmet (Spetsnaz Helmet) -- The best head protection in the game, capable of surviving a Kar98k headshot with health remaining.
• Level 3 Military Vest -- Maximum body armor that significantly reduces incoming damage and has the highest durability of any vest.
• AWM (.300 Magnum Sniper Rifle) -- The most powerful sniper rifle in PUBG, capable of one-shot kills through Level 2 helmets. Comes with a supply of .300 Magnum ammunition.
• Groza (7.62mm Assault Rifle) -- A devastating close-to-mid range assault rifle normally found only in care packages, featuring extremely high damage per second.
• Ghillie Suit -- A rare wearable camouflage that makes you nearly invisible when prone in grass or foliage. A game-changer in final circles.
• 8x CQBSS Scope -- A high-magnification scope ideal for long-range engagements, adjustable down to 4x for versatility.
• Suppressor (AR/SR) -- Sound suppression attachments for assault rifles or sniper rifles that drastically reduce your audible firing signature.
• Extended QuickDraw Magazine -- A combined attachment that increases magazine capacity and reduces reload time, available for AR, DMR, or SR.
• MedKit -- Restores your health to 100% over 8 seconds, the only healing item that provides a full heal.
• Adrenaline Syringe -- Fills your boost bar completely, providing sustained healing over time and a movement speed bonus.
• First Aid Kit -- Heals up to 75% health over 6 seconds, a reliable and commonly spawned medical supply.

Pro Tips & Strategy for Deston Secret Rooms

Knowing where the rooms are is only half the battle. Follow these strategies to consistently loot Deston's Security Rooms and survive the encounter:

1. Land near keycard spawns first. Prioritize dropping at the Concert Hall, Lodge, or Riverbay to grab a Security Keycard before other players. Having the keycard early gives you the flexibility to hit any Security Room on your rotation path.
2. Check our interactive map before queuing. Study the Security Room locations on the map above so you can plan your drop and rotation based on the flight path. Knowing exact building positions saves precious time in-game.
3. Listen for nearby enemies before opening. The sound of a Security Room door opening is audible to nearby players. Before you swipe your keycard, clear the floor and listen for footsteps. Getting caught mid-loot in a small room is a death sentence.
4. Loot fast and move out. Do not spend more than 15-20 seconds inside a Security Room. Grab the highest-priority items first -- Level 3 gear and the AWM should be your top picks -- and get out before someone pushes your position.
5. Combine with nearby loot spots. Plan a route that chains a Security Room with adjacent high-loot buildings. Downtown skyscrapers often have excellent floor loot on other levels, so clear the building top-to-bottom after hitting the Security Room.
6. Rotate early toward the circle. After looting a Security Room, you are likely carrying some of the best gear in the lobby. Avoid unnecessary fights and rotate toward the safe zone early to secure a strong position for the mid-game.

Deston Secret Rooms vs Other Maps

Each PUBG map has its own unique approach to secret rooms and hidden loot mechanics. Unlike Erangel's underground bunkers, which are accessed through hidden tunnel entrances and require players to navigate below ground, Deston's Security Rooms are found high above the streets inside glass-walled skyscrapers. This vertical placement creates a very different tactical dynamic -- you need to control elevator shafts and ascenders rather than tunnel chokepoints. Vikendi's security labs use a Crowbar mechanic instead of keycards, requiring players to find and carry a melee tool to pry open reinforced doors. Taego's Error Space locations offer a completely different experience with their mysterious self-contained rooms that feel disconnected from the main map. Rondo's hidden bunkers are buried beneath the map's compact urban landscape, rewarding players who memorize the tight underground layout. And Paramo's stone door secrets tie into the map's volcanic and archaeological theme with ancient-styled locked chambers. Deston remains one of the most rewarding maps for secret room hunting due to the sheer number of Security Rooms available and the density of keycard spawn points across its massive urban footprint.
