Co-op & Convergence
Deploy solo or in a private 1–4 subject Investigation cell—or enter Convergence, where time-displaced expeditions spot one another as distant flashlight echoes and merge up to 8 subjects when a blackout hits.

01 // Field Operations
Expeditions Out of Sync
Step out of a fortified safe station into an endless, multi-floor belt of yellowed office partitions, humming fluorescent ballasts, maintenance sub-levels, and flooded tile halls—where every squad enters on a slightly different date, and every repair or lost pack persists in the world.
Spatial Proximity Voice
Hear your squad the way sound actually travels through empty offices—muffled by drywall, echoing across damp tile, and fading down stairwells. Coordinate via chest radio, hand gestures, or silence—because entities listen too.
The DESYNC Refuge
Recover calibrated maintenance modules and materials to physically upgrade your Refuge. Unlock new signal bearings, rest bunks, shared cell storage, and deeper extraction anchors without artificial level-gating.
Anomalies & Traces
Photograph, frequency-scan, and sample lethal anomalies for your guild's shared Anomalidex. Spray orientation stencils, deploy persistent field devices, or recover the dropped pack and VHS tape of an explorer pulled out before you.
Safe Zone // Refugio
Prepare, Deposit, Re-enter
Cross the threshold back into the Refuge to bank recovered hardware, review contracts, and physically expand your communications array.
10 m Grid // Plano de Campo
Shared Field Cartography
Only what your squad observes is drawn. Track multi-floor stairwells, color-coded teammate paths, modified zones, and active green anchors.
ADX-21 // Anomalidex
Classified Entity Archive
Compile photographs, 47.3 kHz telemetry frequencies, and physical samples to unlock verified behavior profiles and survival countermeasures.

The DESYNC Field Protocol
Why the Clocks Never Match
In 1987, the DESYNC Foundation lost contact with an entire chain of sub-surface maintenance and relay stations. The rooms did not collapse—they repeated. Miles of damp acoustic carpet, buzzing sodium ballasts, and concrete service shafts folded into an unmapped interior belt that refuses to obey baseline time.
Today, regional DESYNC guilds dispatch hazmat-sealed field subjects from fortified link stations to reclaim abandoned infrastructure, restore communications relays, and execute containment operations. No two expeditions enter on the same timestamp: your squad may step across the threshold minutes—or years—apart from the team whose flashlight you just saw flicker down the hall.
- Directive 01 · Maintain Sync Your visor camcorder and telemetry implant anchor you to the Refuge. Three direct impacts—or catastrophic exposure—trigger an emergency pull-out, leaving your backpack and recorded tape where you fell.
- Directive 02 · Trust Nothing Unverified Decommissioned Mk.VII maintenance units still patrol darkened sectors by sound. Worse things wait for the lights to cut out, separate squads, and repeat a teammate's real voice back through the dark.
- Directive 03 · Bring Something Back Every recovered module, mapped stairwell, and biological sample permanently alters your Refuge and opens deeper bearings for the next outing.

04 // Fair-Play Charter
Free-to-Play. Cosmetics Only. Zero Pay-to-Win.
Everything that helps you survive, navigate, communicate, or progress in DESYNC PROTOCOL is free for every player. Optional requisitions support ongoing development strictly through visual customization—enforced by automated fairness checks in code.
100% of Gameplay & Progression
- Full co-op access (1–8 players), all strata, anomalies, contracts, and Refuge upgrades.
- Every functional tool, battery, field device, backpack capacity, and survival mechanic.
- All 8 tactical gesture-wheel commands (Follow Me, Point, OK, Wave, Halt, Relay Step, Silence, Sit)—communication is never sold.
- Standard hazmat suit variants (Service, Ceramic, Signal, Inspection) and earnable mastery plates.
Strict Zero-Advantage Guardrails
- Visual gear only: themed suits, backpacks, sewn patches, 3D keychains, sprays, radio & flashlight finishes, respirator filters, REC frames, and nameplates.
- Measured parity: paid flashlights cast identical beams; REC frames never grant night vision; spray stencils match standard paint area; suit luminance is bounded so darkness cannot be bought.
- No loot boxes or premium currency tricks: direct, transparent real-currency pricing—you always get the exact item shown.
- No dark patterns: zero mid-expedition store prompts, zero fake countdowns, and double-step purchase confirmation.

Frequently Asked Questions
What is DESYNC PROTOCOL?
DESYNC PROTOCOL is an online cooperative horror and exploration game set in the Backrooms, developed and published by UNDEFINED STUDIO SL for Windows PC. You play as a hazmat-equipped subject sent from a persistent Refuge to map shifting architectural strata, document dangerous anomalies, recover communications hardware, and make it back alive.
Can I play solo, or do I need a full 8-player group?
Both. You can explore solo at your own pace, run private persistent campaigns with 1–4 friends in an Investigation cell, or enter public Convergence outings where separate squads can cross paths and merge up to 8 subjects during blackouts. Your personal progress and Refuge milestones carry forward whether your friends are online or offline.
Is it really free-to-play without pay-to-win or loot boxes?
Yes. The base game, every playable biome, all survival equipment, Refuge upgrades, and all 8 tactical communication gestures are completely free. We sell only optional cosmetics (suits, patches, charms, sprays, equipment finishes, REC frames, nameplates, and an optional time-limited Founders Pack) with transparent real-currency pricing—zero loot boxes, zero stats, and zero gameplay advantages.
Which platforms will DESYNC PROTOCOL launch on?
DESYNC PROTOCOL will launch first on PC (Windows) via the Epic Games Store, followed later by Steam.
Is proximity voice chat recorded or stored?
No. Player-to-player proximity voice chat is transmitted live through Epic Online Services voice relays and is never recorded or stored by us. Optional 18+ voice interactions with in-game survivor NPCs are disabled unless you accept the policy and can be muted at any time; full technical details are documented transparently in our Privacy Policy.
How do I view, export, or delete my account data?
Directly inside the game under SETTINGS > ACCOUNT, you can copy your pseudonymised account identifier, download a complete JSON copy of your stored data, or permanently delete your account immediately—or contact [email protected] at any time. Read our full Privacy Policy for complete retention and GDPR details.
