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 22 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

Simply marvelous! Bravo!
Bastante flojete
This is a really solid anomaly game and I definitely recommend giving it a try! The anomaly's were fun and some were even so subtle that it was hard to notice but I eventually got all of them, which was fun to do. I had a good time with this one and even got a bit jump scared at some points. Give it a try!

The Underpass is yet another anomaly-hunting game that, unfortunately, fails to impress in any meaningful way. Somewhere between the extremely limited and empty environment, the dull gray visuals, and the bland—at times even annoying—anomalies, my interest faded quickly, despite the fact that I genuinely enjoy this genre. There are no jump scares. There are no clever anomalies that actually reward careful observation. And most importantly, there’s no tension. No sense of unease. No thrill. In other words, I can’t really recommend The Underpass, unless you’ve already played every other anomaly-hunting game out there and are simply desperate for more.
