Modeled estimate, not a reported figure. How we estimate →
Prices
The United States storefront in every case, so this compares stores and not countries.
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
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.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.

Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Sums Steam only; PlayStation publishes no volume signal, so the true total is higher by an unknown amount.

getting the shadow mantle alone has to be one of the worst experiences ive ever in gaming ever, worse then elden ring, i genuinly regret buying this game and undertale because of how absalutely horrible that boss is. not to mention that if at any point in your attempt at fighting the absalute worst boss ive ever seen (not the knight btw) you quit the game you restart several long and boring minutes back.
