ZOO PROTOCOL is a co-op sci-fi horror for 1–5 players about escaping an abandoned energy plant on a long-forgotten planet.

You wake from cryosleep inside an abandoned alien industrial complex, where the system registers you as one of its employees and forces you to work.

Explore the facility, search for hidden rooms, and read the documents and logs left behind by the previous crew. Find out what really happened here and find a way to escape before it’s too late.

Work inside the complex is not a single task, but an entire system of interconnected processes.

One problem leads to the next, and routine work quickly turns into a fight for survival. But the more efficiently your team performs, the deeper you advance into the complex.

Gradually, it becomes clear that you are not maintaining a simple power system, but a machine whose true purpose is far more vile than it first appeared.

FEATURES

Play solo or in co-op for up to 5 players Distribute responsibilities, coordinate your actions, and prevent a chain reaction of failures across the complex. Three difficulty settings — Easy, Normal and a dedicated Solo mode balanced for a single operator: one person can run the entire production cycle and see the story through to the final boss.

Story through progression Earn resources, unlock new opportunities, and reach sealed-off areas of the complex, where the true nature of what is happening is hidden.

Care for anomalous creatures Each entity requires monitoring, feeding, and strict compliance with containment conditions. Violating protocol leads to horrifying consequences.

Analog system control Monitor the complex, stabilize key indicators, and deal with breakdowns and emergencies through outdated panels, switches, and equipment.

Escalating pressure Energy shortages, contamination, containment breaches, and staff mistakes gradually turn each shift into a catastrophe.
