About The Anomaly Protocol
The Anomaly Protocol is a psychological horror game in which you investigate an endless series of apartment floors. You inspect each floor for irregularities, compare what you see with what should be there, and document your findings using a checklist. If you find an anomaly, you mark it; if not, you record “no anomaly” and move on.
Investigate the floors
The building’s empty halls, flickering lights and strange layouts become increasingly unsettling as you descend. The floors unfold procedurally, and reality begins to bend: sounds echo in unexpected places, objects seem to shift behind you, and the checklist may not be enough to protect you from what is waiting. Every flicker, misplaced object or eerie silence could be a clue or a trap.
Record your findings
Your decisions affect what comes next. The game’s tension comes from careful observation and uncertainty rather than jumpscares, as routine documentation gives way to psychological disarray. One overlooked detail or mistaken assumption could determine whether you complete the protocol.
