PC Game Pass isn't just a revolving door of massive blockbusters; it's a goldmine of bizarre developer jokes, ARG-level community puzzles, and horror set-pieces tucked away behind fake walls. While most subscribers blow through main campaign waypoints, developers like Gunfire Games, Bethesda, Arkane, and Round8 left deeply obscure rooms and tributes that 95% of players sprint right past. From an actual cosmic horror infestation aboard a forgotten research vessel to a backrooms glitch dimension that required dataminers to crack, these are the best secret locations and easter eggs lurking inside your PC Game Pass subscription right now.
Remnant 2: Breaching the Corrupted Backrooms for the Archon Class
Gunfire Games knew players would datamine Remnant 2 the second it landed on PC Game Pass, so they turned that expectation into the most convoluted secret archetype in modern soulslike history. Deep within the fractured geometry of The Labyrinth sits a fractured stone archway shielded by a shifting, red-glitched data field. Interacting with it normally instantly kills you. To bypass the corruption and step foot into the legendary yellow-walled "Backrooms" dimension, your character must become completely corrupted by equipping an ultra-specific combination of items across every single inventory slot.
You can't just stumble into this. You have to finish a full campaign roll, level two separate archetypes to specific benchmarks, and scavenge multiple worlds for gear that seems entirely unrelated until worn simultaneously. Much like piecing together complex hidden builds in our Far Cry 6 beginner build breakdown, getting this sequence right requires zero room for error.
| Slot Category | Required Equipment | Source Location | Function in Unlocking |
|---|---|---|---|
| Prime Archetype | Explorer (Level 10) | Post-Campaign / Brabus | Provides the required 'Fortune Hunter' skill |
| Secondary Archetype | Invader (Level 5) | Root Earth / Quartermaster | Grants 'Worm Hole' blink ability |
| Armor Set | Realmwalker Set | Whispers in Ward 13 | Visual catalyst for corrupted avatar |
| Long Gun & Sidearm | Ford's Scattergun & Cube Gun | The Red Throne & Labyrinth | Legacy connection to previous Remnant lore |
| Melee Weapon | Labyrinth Staff | Labyrinth Hidden Boss Arena | Channels the realm’s native energy |
| Relic | Void Heart | Alepsis-Taura (N'Erud) | Grants dark void status condition |
| Rings & Amulet | Leto's Amulet, Amber Moonstone, Black Cat Band, Anastasija's Inspiration, Zaniah's Malice | Ward 13, Cass, Root Earth | Finalizes the exact corrupted stat profile |
Once you are geared with this precise loadout, your character model permanently radiates red digital static. Return to the fractured portal in the Labyrinth, interact with the corrupted biomaterial, and the door swings wide open. You are transported to a 90-second timed labyrinth mimicking internet "Backrooms" creepypasta lore. Use the Fortune Hunter skill immediately to highlight loot drops through the walls to extract the Strange Box (which crafts the Archon archetype engram), the Bisected Ring (infinite stamina at the cost of taking 25% extra damage), and the Gunfire Security Lanyard.

While much of Bethesda's Starfield leans heavily into grounded "NASA-punk" wonder, buried deep in the Schrodinger star system sits an unlisted nightmare. Grav-jump to Schrodinger III, and you'll spot an unmarked ship drifting in orbit: The Colander. There are no distress beacons, no comms chatter, and no quest markers pointing you here.
Docking with the vessel immediately turns your screen into an environmental horror movie. The ship operates on auxiliary emergency lighting, interior gravity is completely deactivated, and discarded research slates document a crew slowly losing their minds to an aggressive biological specimen harvested from an uncharted world. Navigating the twisting zero-G ventilation ducts brings you straight into the central cargo hold, where you'll confront the Interloper—a massive, level 85 extraterrestrial monstrosity with terrifying movement speed and high damage resistance. Slaying it rewards you with high-end contraband and a massive XP dump, providing the exact eerie, isolated space salvaging tone we detailed in our Everspace 2 secret locations and hidden rewards guide.
If you'd rather celebrate human history than fight for your life in an air vent, make a detour to Luna (Earth's moon in the Sol system). Before you land, stop by The Lodge on Jemison and head into Sir Livingstone's bedroom. Grab his personal journal off the desk. Reading it permanently adds the Apollo Moon Landing Site activity to your mission log. Fast travel down to the newly unlocked coordinates on Luna, and you can walk up to the actual Apollo 11 Lunar Module sitting silently on the dusty regolith, topped off with a collectible vintage Apollo Snow Globe resting right on the rover ascent stage.
Halo Infinite: The Giant Sandwich Shrine and Hidden Arcade Machine
343 Industries filled Zeta Halo's open world with combat encounters, but the designers also tucked away some of the weirdest environmental easter eggs the franchise has ever seen. The crowning achievement is the subterranean Sandwich Shrine. Tucked into the steep mountainous terrain south of FOB Novis, look for an unassuming crevasse sliced directly into the rock face. You'll need an upgraded Grappleshot with quick cooldowns to scale up into the ceiling fissure.
Squeeze through the claustrophobic cave tunnel, and the ambient combat music suddenly fades out, replaced by a low, reverent choir chant. Dropping into the inner cavern reveals a cluster of Grunts frozen in worship around an impossibly massive, photorealistic submarine sandwich sitting on a stone pedestal. It is complete with cross-sectioned salami slices, textured lettuce, and glowing energy stones acting as votive candles. Shooting the sandwich produces metallic ricochet sounds rather than squishy food impacts, proving the Master Chief's universe has a sense of humor about its legendary artifacts.
If you head further north near Outpost Tremonius, comb the sheer mountain cliffs bounding the western edge of the facility. Tucked behind hexagonal Forerunner spires is an obscured cavern opening draped in shadow. Grapple inside to discover a fully powered, functioning retro 8-bit arcade cabinet. The screen displays an arcade rendition of Master Chief battling Banished forces, running a custom chiptune loop of the iconic *Halo* theme. These kinds of high-effort, low-visibility tributes reflect the legacy secret-hunting passion found across classic arena shooters, rivaling the vintage weapon unlocks we ranked in our Far Cry 3 Blood Dragon weapon tier list.
Prey (2017): Talos I’s Hidden Smuggler Stashes and Developer Tributes
Arkane Studios' Prey is essentially one colossal, interconnected puzzle box, and its most lucrative easter egg loop is the station-wide smuggling ring that the tranStar corporate board never uncovered. Scattered across the pristine retro-futuristic corridors of Talos I are tiny, unassuming wall panels equipped with a dead giveaway: a soft, pulsing red light bulb mounted directly above the frame.
These panels do not have keypads or hackable interfaces. To crack them open, walk up with your standard Wrench and smack the red light three times in rapid succession. The magnetic lock trips, swinging the panel open to reveal a hidden dead drop compartment loaded with Neuromods, Typhon Lures, exotic fabrication materials, and Weapon Upgrade Kits that radically accelerate your character progression.
You can track down six distinct smuggler dead drops across the campaign:
- Talos I Lobby: Mounted high on the wall directly above the decorative display case near the Arboretum transition bulkhead.
- Arboretum: Tucked into the stone wall pathway winding up toward Alex Yu's private greenhouse.
- Hardware Labs: Located inside the second-floor atrium hallway right outside the Machine Shop airlock.
- Cargo Bay: Hidden inside shipping container staging area Cargo Bay A, behind the primary defensive turret barricades.
- Life Support: Mounted along the maintenance descent corridor leading down to the water treatment pumps.
- Crew Quarters: Located inside the fitness center foyer, obscured by the decorative foliage planters.
Beyond the smuggling network, Arkane tucked their own development team directly into the game. In Hardware Labs, using the GLOO Cannon to climb into the rafters above the Ballistics Lab reveals a sealed maintenance closet marked "Looking Glass Tech." Smashing your way inside uncovers early prototype projection screens displaying internal developer bloopers, debug wireframes, and humorous audio logs poking fun at early physics engine glitches.
Lies of P: The King of Riddles Trinity Chambers and Cryptic Vessels
Round8 Studio's gritty, Belle Époque soulslike hides an entire sub-narrative behind ringing payphones. As you explore the decaying streets of Krat in Lies of P, certain disconnected telephone booths will randomly begin shrilling with an incoming call. Answering them connects you to Arlecchino, the self-proclaimed King of Riddles. Answering his philosophical quandaries correctly rewards you with Trinity Keys, which unlock massive stone vault doors bearing a distinct green triangle emblem.
Tracking down these doors turns Krat into an elaborate treasure hunt that most players miss because the doors are located miles away from the phones where you receive the keys:
- Workshop Union Culvert: Found near the fiery rolling boulder tunnel. Opening this vault yields the Blue Blood's Tailcoat and valuable Quartz upgrade materials.
- St. Frangelico Cathedral Chapel: Located at the base of the massive wooden gear-climbing puzzle room, guarding the Black Cat's Amulet.
- Estella Opera House: Hidden right below the burning chandelier drop before the King of Puppets fight.
- Krat Central Station: Tucked into the monster-infested transit corridors, unlocking the Workshop Master's Workwear.
The real secret isn't just the loot; it's the final chamber inside the Arche Abbey. With the Chosen One's Trinity Key in hand, you breach Arlecchino's true personal study. Here, you discover the King of Riddles isn't just a voice over the wire; he is a fully conscious puppet serial killer strapped into a maintenance frame surrounded by the corpses of his victims. Exhausting his dialogue and deciphering his final cryptic vessel unveils the dark origins of Krat's puppet frenzy and rewards you with the Moon World's Warrior Badge, delivering an essential piece of lore for true completionists.
PC Game Pass Secret Locations & Mystery Matrix
Hunting down obscure corners in massive titles often requires planning out your save states, especially when some secrets lock permanently once you hit campaign points of no return. Use this breakdown to plan your next Game Pass deep dive without wasting hours backtracking through cleared zones.
| Game Title | Secret Name / Easter Egg | Key Prerequisite / Tool | Primary Reward | Missable? |

How to Optimize Your PC for Secret Hunting
Finding tiny wall panels, hidden rock crevasses, and obscured zero-G entry points is practically impossible if your PC setup isn't tuned for high visibility and sharp spatial imaging. When hunting for subtle environmental tells—like the faint red flicker of Prey's smuggling panels or the low hum of Halo Infinite's arcade machines—your hardware configuration makes all the difference.
Start by disabling aggressive Motion Blur and Depth of Field across all these titles. Both post-processing filters artificially smear peripheral details when your camera sweeps past hidden vents, fake walls, and dark cliff niches. If you're running into micro-stutter while exploring demanding open-world biomes, dial in your frame rates using our Filament settings for higher FPS guide to keep your render pipeline silky smooth.
Next, adjust your Field of View (FOV). Games like Halo Infinite and Starfield default to a narrow 75 to 80-degree horizontal cone. Pushing your slider to 95 or 105 degrees dramatically expands your peripheral awareness, allowing you to spot elevated ledges, grapple points, and hidden switches without having to constantly pan your camera to the ceiling. If you run into unexpected system hangs while running high-overhead titles on PC Game Pass, be sure to check our battle-tested Elex PC fixes for crashes and FPS drops to keep your rig stable during marathon exploration sessions.
Finally, do not rely on standard stereo speakers. Secrets like the King of Riddles' payphones in Lies of P and the Sandwich Shrine choir in Halo Infinite are entirely located via subtle 3D directional audio cues. Equip a quality gaming headset with Windows Sonic or Dolby Atmos for Headphones enabled. When developers take the time to build entirely unique, unlisted locations into PC Game Pass titles, listening for that slight change in room reverb is usually the exact clue that tells you you've stepped off the beaten path.
Whether you're speed-leveling characters in RPGs using our Kakarot leveling and Zeni farming guide or simply looking to squeeze every drop of value out of your monthly subscription, chasing these hidden rooms reminds us why we love PC gaming in the first place: the thrill of finding something you were never technically supposed to see.
