You step through the doors of a shelter that no one has ever returned from, together with your team. Your objective is to explore maze-like rooms and corridors, collect valuable loot, and descend into deeper layers each time. The deeper you go, the greater the rewards—but the cost becomes heavier.


☢️ What is Anomaly Protocol ?
Anomaly Protocol is an online co-op survival horror game set in the depths of an abandoned radiation laboratory. Together with your friends, you must rescue radiation-affected survivors, gather valuable data, and complete each floor's quota to open the next.
But every choice has a cost. As radiation spreads, not only the environment—but the people—begin to change.

No two floors are ever the same in Anomaly Protocol.Each level and room is procedurally generated to ensure that every player experiences a new narrative.Some rooms are eerily quiet, while others seem one breath away from screaming.The system is built to keep players constantly on edge—just when you feel safe, everything changes.
Radiation isn’t just harmful—it’s intelligent.Every room has its own radiation level.Some are relatively safe, while others are immediately dangerous.And remember: The higher the radiation, the easier it is for entities to detect you.This is not just a game of reflexes—it’s a game of strategy.
We are currently working on integrating a shop system that aligns with the atmosphere and design of the game. While this feature is not yet available in the current version, it is something we hope to introduce in a future update.
As a solo developer, I'm continuing to develop this feature with the goal of giving the in-game currency meaningful use, and shaping it based on valuable feedback from players.
The goal is to make this system available as soon as it’s ready to add depth and purpose to the overall experience. Can You Design Tension?
We believe you can. Anomaly Protocol doesn’t rely on jump scares alone. Sometimes silence is more terrifying than a scream. Sometimes a single footstep triggers the wrong sound. This isn’t random—everything is built to make you uncomfortable.
We believe fear is not just a reaction—it’s a crafted experience.
