Tenebris CD Key

Tenebris is a single-player, first-person horror puzzle experience set in an abandoned subway system where darkness isn’t your only threat. You awaken alone inside a silent subway car as failing lights flicker overhead and the city above feels impossibly distant. When the doors finally open, they reveal only endless tunnels, stale air, and the unsettling sense that something is already listening.

Armed with a fading flashlight and a radio spitting distorted fragments of voices, you must push into the station’s depths and search for the power switch that can restore the train—your only way out. The route forward is never familiar: the subway tunnels form a procedurally generated maze, ensuring each attempt reshapes the path, the choices, and the risks. Every turn can be a dead end, every corridor can lead deeper into the unknown, and every run demands new decisions.

Survival is built around careful resource and sound management. Light is limited, and your flashlight battery won’t last forever—forcing you to decide when to illuminate your surroundings and when to move blind. A crank flashlight offers a lifeline, but generating power comes at a cost: noise. In Tenebris, sound is danger. Footsteps, breathing, and interaction with the environment can draw attention, and the creature stalking the tunnels reacts to what it hears.

To endure the darkness, you’ll rely on alternative ways to perceive your surroundings. Use echolocation to read space beyond your beam, and interact with objects to create useful information. You can pick up and throw items to produce sounds that reveal the layout ahead—but every distraction risks becoming an invitation.

Key features:

• Atmospheric, tension-driven first-person survival horror with puzzle elements
• Procedurally generated tunnel maze for high replayability
• Resource-limited exploration focused on flashlight power and smart timing
• Echolocation navigation to sense the environment beyond the light
• Object interaction and sound-based tactics—useful, but dangerously loud

In the silence of the underground, your best tool might be restraint. Move too carelessly, and whatever lurks in the dark will find you.
