Overview

About this game

ARB: Museum is a short first-person anomaly investigation game where you serve as an agent of the Anomalous Research Bureau, assigned to monitor a museum during repeated night shifts. Some nights appear normal, others contain subtle (or not so subtle) changes that persist only for the duration of that night.

Your task is simple, patrol the dark museum hall each night, observe carefully, and use your security office terminal to accurately report only what deviates from the baseline night.

  • Explore the creepy museum and exhibits over a series of nights

  • Report any persistent anomalous activity you find for that night

  • Successfully report accurate data across each night to complete your assignment

  • Failing to report accurate data corrupts your investigation, requiring it to be restarted

  • Over 50 anomalies to discover

  • 20-45 minutes for a session playthrough

  • Anomalous activity is randomized so no two playthroughs are quite the same
