No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. Reviews and prices only.
What Darkness Conceals, Terror Reveals Mystery sounds through the haunted halls and rings from the rafters of a deserted museum. Was this a failed dream or was it the waking nightmare of an eccentric old man? Where is the museum's creator, and the other ill-fated visitors who disappeared so long ago? You enter, with nothing but your wits to help you survive. Wretched spirits watch for the innocent, the unwary, ready to steal your life's essence. Can you hear the shrieks now, the howls and moans and wails? They're waiting for you. Experience spine-tingling first-person adventure. Unravel a mysterious storyline full of twists and turns. Witness ghostly live-action video sequences. Explore a world filled with bizarre 3-D imagery. Startle your senses with chilling music and eerie sound effects. Roam at will throughout the museum - non-linear game play lets you re-visit puzzles that have stumped you. Play again and again - location of items change and puzzles vary each time!
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.
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 GOG · Trending · United States over the last 30 days: the 141 chart moves that followed a price cut of more than 20% went a median of 2 places away from #1, and the 6,557 moves with no price cut behind them went nowhere. 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.
