About Observation Protocol
Observation Protocol is a first-person psychological horror game about working a shift at a place scheduled to stop existing. You're stationed at an external monitoring post assigned to a liminal office space. It's a facility that exists outside of normal space, discovered and monitored by an organization that has now scheduled the passage to be permanently closed. Your task is straightforward: watch the camera feeds, identify discrepancies, and photograph what you find. REMOTE MONITORING: Then the power cuts. Monitoring equipment goes dark, and protocol has an answer for that too: go in. You're issued a camera. There is no door. The wall ahead phases out, and you step through into the space you've been watching from outside. Same offices, same corridors. Except now you're inside them instead of watching a feed of them. You're not alone in there. ON SITE: You have until 6 AM. Photograph every discrepancy you encounter, then make it back through the entrance before the organization closes the passage. Stay past 6 and you're stuck inside when it does. There's no saving mid-shift. Each session runs about thirty minutes, start to end. A liminal horror experience. PSX aesthetic. First person. Singleplayer. No checkpoints.Read more
