ARCHIVED_PROTOTYPES

Each wing of the facility housed an independent prototype line. All were scrapped. None were fully shut down.

Colonial reenactment units with furnace cores. Detect heat signatures. Glow in darkness. Move in unpredictable bursts.

Core Systems

GAMEPLAY_MECHANICS

Five interlocking systems that reward patience and punish habits.

Sound Stealth

Every enemy reacts to a different sound type. Brutus hears footsteps. Vixen hears voices. Aviar tracks camera movement. Marrow hears everything. Silence is a tool — use it.

Power Rerouting

Redirect power to lock doors, activate emergency lights, or disable units temporarily. The catch: rerouting changes the facility layout. Every choice reshapes the map.

Adaptive AI

Marrow records your behavior across deaths. Your hiding spots, your routes, your flashlight habits — he remembers all of it. Each attempt he becomes harder to predict.

Environmental Hazards

Collapsing floors, electrified water, steam vents, unstable catwalks. The facility itself is degrading. Hazards can be used against enemies — or kill you first.

Multi-Ending System

Three endings determined by your choices in Acts 9 and 10. No binary prompts — your actions and hesitations accumulate into the outcome.

New Game+

Marrow carries all accumulated behavioral data into a second run. He knows your playstyle before you make your first move. The facility remembers you.

Original Soundtrack

OST_MANIFEST
