The Artifact Protocol is a first-person psychological horror game where every artifact traps you in the final moments of someone else’s life. You play as Anthony, an imprisoned ex-soldier forced into a classified testing program, promised freedom if you can survive. One by one, you’re sent into reconstructed memories of the dead, each trial a different nightmare.But the deeper you go, the less you’re sure if you’re living their memories… or your own.
This isn't no ordinary horror... this is not a safe dream, it’s a trap built from tortured minds. Most who enter never return, even veteran horror fans have failed to survive even the first artifact... can you?
Five Nightmares In One: Each artifact is a standalone nightmare with its own setting, monster, and psychological theme.
Challenging Survival: Most who enter don’t escape the first artifact. No handholding, no walking simulator, only your wits and your will to survive.
Custom Voice Acting & Story-Driven Experience: Every trial is brought to life with original voice performances and a narrative that unfolds through atmosphere, sound, and discovery.
Deep Environmental Storytelling: Learn each victim’s story through living it, not just watching it.
Adaptive Monster AI: No two encounters feel the same. Each creature learns, reacts, and hunts in its own terrifying way.
Completing the main story unlocks new layers of horror:
Nightmare Mode: A brutal one-life challenge with a new "Observer" and exclusive narrative voice lines that reveal hidden lore.
Multiple Challenge Gamemodes: Extra challenge trials that push your survival skills even further.
This isn’t about cheap jumpscares. The Artifact Protocol is built on dread, loss, and fractured identity... horror that lingers long after you’ve shut the game down.
The Artifact Protocol is designed as an intense horror experience you can survive in one sitting, with new modes and hidden story layers waiting to pull you back...
