The Kharzov Effect

1985. Your friend never came home.

Billy's bike is at the gates. Something moves beyond the fog. You go in anyway.

A Horror Puzzle Built From the Inside Out.

There are no weapons. There is only hiding, running, and thinking.

first-person horror puzzle set at the fog-drenched Oregon estate of Dr. Kharzov.

First-person stealth horror — navigate the grounds without a weapon. Your only tools are your wits, your patience, and the shadows.

Monsters with distinct detection — some see you. Some hear you. Some feel you. Learn how each one hunts, or don't survive.

Escape-room-style environmental puzzles — every locked door, every sealed room has an answer hidden in the world around you. No hand-holding.

Atmospheric environments — a world designed to keep you guessing. BTW, do you like analog horror?

Period-accurate details from the 80's — before the internet. Before mobile phones. Before anyone would believe you. Just you, the dark, and whatever Kharzov built in there.

Layered narrative mystery — the puzzles are part of the story. The deeper you go, the bigger the lore.

Meta gaming & ARG-inspired mystery — a hidden thread built entirely

from easter eggs that transcends the game itself. Find it if you can.

Doorway Studios wanted to build something that didn't exist yet — Traditional scares weren't enough — we wanted puzzles that challenge your mind, lore that rewards curiosity, stealth that makes you sweat, and moments that make you question whether the game is playing you.

The Kharzov Effect is the first chapter of an unfolding story. Chapter 2 is already in active development.
