Every map in ARC Raiders hides layers of secrets tucked behind locked doors, coded puzzles, breachable environments, or environmental quirks players discover only through deliberate exploration. These spaces matter because they reward exploration with high-value loot, rare crafting components, or lore fragments that sit outside the main loop of open areas and standard containers. Learning where these rooms are, how to access them, and what you might find inside can change how you approach every raid. Suddenly, you won’t be fending off PvP raiders, ‘nading ARCs, or doing the most to keep yourself alive; you’ll instead be transported to doing Easter Eggs in classic Call of Duty: Zombies.

This guide breaks down everything known about secret rooms in ARC Raiders across all current maps. Some areas require keys or puzzle solutions. Other spaces open only once per raid under specific conditions. A few remain controversial, rumored, or partially undocumented by the community. The objective here is clarity: what is documented on the wiki, what players are still investigating, and what each location offers to a Raider who takes the time to find it. Knowledge of secret rooms gives you an edge every time you step onto the surface.

So What IS a Secret Room in ARC Raiders?

Secret rooms include several distinct categories of hidden content. There are locked rooms that require keycards or puzzle items (which are made obvious to you through your Raider inventory). There are map modifiers, like hidden bunkers, that open only after completing objectives. There are hidden loot caches off beaten paths that reward careful navigation. Some areas reward curiosity rather than force. Understanding these categories helps you track what to look for and what to bring into a raid.

Locked rooms, once accessed, often contain a higher density of rare containers and loot crates than surrounding areas. These rooms are sometimes obvious from the exterior, but the game hides their access behind doors that look normal. Puzzle rooms, in contrast, require actions scattered across the map. Completing them unlocks access to chambers not visible at the beginning of a raid. Hidden loot caches are not always enclosed rooms. These are tucked spaces under debris, in collapsed structures, or behind destructible elements that go unnoticed by casual players. All contribute to the game’s depth far beyond the typical open environment.

Community documentation on secret areas has grown alongside the game itself. Players share locations and route strategies in forums and subreddit threads to help others locate high-value rooms and breachable doors. These community efforts often fill gaps left by official documentation. Knowledge shares mean Raiders do not have to discover every entry on their own, but don’t believe everything you hear: while these rooms are often helpful, clickbait TikToks will have you think they’re all full of gold-tier items. That’s not true, but as the meta evolves and players invest more time exploring every map, additional rooms are cataloged, refined, or corrected over time, helping all of us find better loot in the Rust Belt.

The Hidden Bunker on Spaceport

One of the most discussed secret locations in ARC Raiders has been a mysterious underground bunker on the Spaceport map. Hitting the bunker is a hot topic because it requires a lot of time investment. The bunker is not accessible by simply running in. To unlock it you must activate four rooftop antennas scattered across the map. Each antenna must be interacted with twice to mark it complete and reveal the bunker’s entrance to the raid. Once all antennas are activated, multiple entrances to the bunker open up west of the Departure Building.

Inside this bunker lies a network of data terminals. Raiders can interact with up to eight terminals, initiating a download sequence that awards experience points once completed. These terminals present a different, more lore-based approach to raiding than typical loot crates. They provide decent raider XP and also tie into deeper narrative elements over time, which has led the community to investigate whether additional secrets exist inside these walls.

The bunker’s presence has generated debate and speculation within the player base. Some think the shackles around the bunker’s puzzle mechanics point to more content yet to be discovered. Players have discussed patterns of light signals on terminals and even reported non-corporeal walls visible from out of bounds, though no conclusive secondary level has been documented.

While the Hidden Bunker remains one of the most intriguing secret spaces in ARC Raiders, it has been removed and returned to the game’s ecosystem numerous times by the developers at Embark. Players widely used exploits to bypass puzzle steps, prompting the developer to disable the event temporarily while adjustments are prepared. This underscores that secret rooms in ARC Raiders are not static. ARC is a living game, almost like Helldivers 2, despite how it might appear on the surface, meaning that the game changes with patches and more player interaction driving development statistics. The bunker may return with revised mechanics, new challenges, or additional rewards in future updates.

Locked Rooms and Key Access Areas

Most maps contain locked areas that cannot be accessed without keycards. These rooms often yield rare loot and valuable crafting materials. Players learn early that acquiring the right keycard significantly boosts their probability of a profitable run. Guides outside the wiki explain where to use the primary keys, mapping them to specific lock doors on each map.

On the Dam Battlegrounds map, the Control Tower holds a key card room players refer to as the Dam Control Tower Key location. This room often contains weapon cases and security lockers that are not present elsewhere in the map. For Raiders who find the key and want to risk the approach, these locked rooms offer a concentrated set of high-value containers.

Buried City, a map known for its labyrinthine corridors and subterranean environment, contains several locked interior spaces that narrow the loop between Corridor entrances and unseen rooms. On this map players have reported breachable storage rooms connected to abandoned highway camps and window jumps that allow entry into otherwise sealed interior spaces. Breaching windowed access points often leads to small rooms with loot shelves that spawn red lockers or weapon crates. Players constantly document these loot areas online, but they have changed even since I began writing this article; stay vigilant, and stay in touch with the community!

Spaceport above ground also contains locked container storage rooms that require specific cards. One example exists on the second floor of the Departure Building. This room, when accessed, often yields multiple red lockers and a security locker in the back.

Blue Gate contains hidden cellar areas as well. Some of these are tied to puzzles within the fortified reception areas or button sequences spread across sections of the map. These interior locked environments can be accessed when players find the right code or fuse sequence, opening a broader section that holds multiple containers worth looting.

Each locked room usually requires one specific keycard or puzzle condition to open. Players track the location of keycards or fuse puzzles early in a raid to plan efficient routes that maximize loot before extraction. Because many locked rooms contain rare or guaranteed loot, they reward preparation even when other Raiders converge.

Puzzle Rooms and Button Sequences

Several maps include puzzles that extend beyond a single door lock. These puzzles sometimes span across large portions of a map and require players to press scattered switches, find matching symbols, or carry items across distances to reach a final unlock. These are among the more complex secret rooms because they require observation and route planning.

On the Blue Gate map, players can encounter puzzle rooms that depend on finding and activating hidden switches or terminal sequences. One set of puzzles begins with powering up three batteries scattered around the ruins of the Ancient Fortress at the south of the map. Once these are placed into fuse boxes around a fortified house, a basement entrance opens that would otherwise remain sealed. This kind of puzzle invites players to explore a wider area rather than focusing on a single high-risk locked room.

Buried City features a large-scale button hunt sequence. There are over a dozen switches hidden throughout the map that must be pressed in the correct sequence to open a sealed room. Completing this sequence grants access to loot that is otherwise unreachable. The only thing is… if another Raider hits a switch out of your order, the whole puzzle falls apart. Coordinate with other raiders, ensure that you have time to hit all the switches, but wait as long as you possibly can. The rewards can include cosmetic items or novelty gear not found in regular containers, making these puzzle rooms feel like Easter eggs rather than strictly combat-reward locations.

Breachable Doors and Unmarked Interiors

Beyond locked rooms that require keys, there are breachable points in many buildings that are not obvious on the map. These are places where players can enter through destruction, high parkour movement, or careful navigation. Community threads catalog these access points because they are not always labeled within the game.

On the Dam Battlegrounds, collapsed sections of monorail or maintenance tunnels lead to small crawlspaces with high tier containers. These spaces often sit outside normal loot loops, which makes them valuable if you discover them early in a raid.

Forest bunker locations with keypad locks yield weapon mods and supplies. These are not part of the main loot route and rarely see competition from other players. The codes to access these areas spawn randomly on documents near research buildings.

The underwater turbine rooms in the dam offer another example of hidden interiors for players to raid. Raiders have found waterproof lockers and purple-to-gold loot tucked beneath turbines in dam environments. These spaces are easy to miss without deliberate exploration but reward extra time spent off the beaten path.

Apartment basements behind movable shelving in some maps also contain multiple military crates and occasionally legendary items. The key to finding these spaces is to watch for irregular environmental markers, such as slight mismatches in shelving positions or surfaces that look destructible. Shoot things! Tap into that Legend of Zelda pot-breaking habit when you’re breaching into suspiciously different rooms.

These breachable and hidden interiors reward players who spend time learning each map’s terrain beyond the obvious routes. Raiders that incorporate these “checks” into their raid-loops often walk away with more rare materials and, perhaps more importantly, blueprints than those who stick strictly to marked POIs.

What Secret Rooms Mean for Players

Secret rooms in ARC Raiders shine a light on how the game values exploration alongside its more obvious goals of combat prowess and ARC knowledge. Unlike shooters that funnel players strictly toward combat zones, ARC Raiders encourages careful study of its maps and layered design. Rooms exist that the game never marks with an icon or map arrow but reward you when you find them.

This system of hidden spaces reinforces the extraction spirit of the game. Players who know their maps perform better because they can bypass high-risk encounters, hit clusters of loot early, and build a better loot economy for future runs. Secret rooms and puzzle spaces make every match about more than firepower. They make it a map knowledge contest.

The community helps document these spaces in wikis and forums, and as updates roll out these rooms evolve. What was once an exploit may become a formal map feature. Locked rooms that could be reached through unintended movement in early tests are now fixed, but new secret puzzle mechanics may replace them. The cycle of discovery keeps players engaged with the world outside the front lines of combat.
