Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 11 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About

ARB: Museum is a short first-person anomaly investigation (spot-the-difference) 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

I came across this game while browsing steam for short games to play on my youtube channel, and this is really a rare gem! lovely graphics, easy controls, and a really fun gameplay mechanic! I'm excited to keep playing and see as many different anomolies as I can You can check out my gameplay here if you're interested: https://youtu.be/4nsEDlU8Fw0
A fun SCP style game where you have to spot the difference. Framerate on steamdeck a bit choppy. Nice visuals and atmosphere. Could use echoey footstep noises. Nice experience.
