Amnesia: The Dark Descent follows Daniel through a largely forgotten past inside an abandoned castle. Exploration and physically simulated interactions make the environment part of solving the mystery, while hiding, fleeing and observation provide protection against its threats. The story is experienced from a first-person viewpoint rather than through a conventional combat campaign. Steam publishes different Windows, macOS and Linux minimum profiles, and the older game’s small storage requirement should not be confused with modern operating-system support. Windows XP-era labels are historical specifications because today’s Steam client requires Windows 10 or later. The macOS text both lists an old range and expressly excludes Catalina and later, while Steam has also ended support for older systems and 32-bit games. Buyers should treat those Mac figures as legacy evidence, not a promise that a current Mac will run it.

Fresh exact Steam US HTML read in cycle manual_20261027_0345. Independently reviewed gameplay, developer/publisher, release context, platforms and separate minimum/recommended sections. Search intent: Amnesia: The Dark Descent PC system requirements, gameplay, supported OS, editions and current US price. No volume or ranking claim; no play-test or checkout. App pages are permitted by observed Steam robots. Referenced official header image fetched as image/jpeg, visually checked as matching product artwork, 460x215 pixels.
The exact official app page establishes Steam application 57300 and its named base-game purchase; bundles, DLC and soundtracks are distinct purchases. Regional checkout and ownership were not tested.
Exact operating-system tabs and minimum/recommended blocks were read separately. Missing values remain null; legacy OS, unusual GPU labels and client support caveats are retained. Requirements are published vendor specifications, not independently measured performance.
Within each availability group, offers for the same game appear first, followed by other games where space remains. Current offers appear first; historical records are labelled. Each card retains its own edition, platform and price region; another edition or game is not a substitute for your purchase.
