Short description
The Anomaly Protocol – Something is wrong with the building. Floors repeat, reality shifts, and you’ve been assigned to investigate. Use your checklist to track anomalies—but the deeper you go, the more the truth slips away.
About this game
The Anomaly Protocol – Investigation on the Endless Floors The Anomaly Protocol is a psychological horror game focused on methodical observation, subtle tension, and liminal atmosphere. As an anomaly investigator, your task is to inspect an infinite series of apartment floors, identifying and documenting irregularities using a structured checklist system. Each floor presents a familiar yet unsettling environment—empty halls, flickering lights, strange layouts. Your goal is simple: observe, compare, and report. If an anomaly is present, log it. If not, mark “no anomaly” and continue. But as you progress, the building begins to shift in ways that challenge your perception. Your task is methodical : Investigate. Compare what you see with what should be. If an anomaly is detected, check it off your list. If nothing seems off, mark it as “no anomaly” and move on. But proceed with caution—this is not just a test of observation, but of your sanity. Each floor takes you deeper, not just into the building, but into something far more unknowable. As you descend, reality begins to bend. Sounds echo where they shouldn’t. Objects seem to shift behind your back. Sometimes, the list itself may not be enough to protect you from what's waiting. What begins as routine documentation becomes a descent into psychological disarray. In The Anomaly Protocol , nothing is random. Every flicker, every misplaced object, every eerie silence could be a clue—or a trap. One wrong assumption, one overlooked detail, could be the difference between completing your protocol and becoming part of it. Key Features: A unique twist on anomaly-hunting: use a checklist to methodically confirm or deny the presence of anomalies. Procedurally unfolding floors: the apartment complex grows stranger the deeper you go. Tension-driven horror: no jumpscares, just a slow burn into madness. Every decision matters—what you mark affects what comes next. Are you prepared to face the unknown? Keep your eyes open, your mind sharp, and your list close. Because once you start descending, there’s no guarantee you’ll find the bottom.
