Download AETHUS: demo, price, and where to buy

Buy AETHUS on Steam or install the free demo. The full game is App 2541530. The demo is App 2822250. On 28 October 2026 the US list price was $19.99, shown at $13.99 after 30% off. Check Steam for the price today.

Steam is the official single source for the US price snapshot: $19.99 list and $13.99 promotional on 28 October 2026. A March review records an older $16-era price; that historical quote does not independently corroborate the current price. Demo-save transfer is promised by Steam and separately described by players; Linux/Proton has a reported manual-transfer exception.

Demo dates and transferring progress

The demo store lists 24 May 2024. Official news also announces a new demo on 23 February 2026, alongside that day’s trailer; these are an initial listing and a later demo revision, not competing full-game release dates. The full game launched 6 March 2026 (Steam and IGN agree).

Steam’s full-game requirements say demo progress carries over. Players describe a shared Windows save location, while a Linux discussion reports that the separate Proton prefixes need a manual copy. Use /faq/ for the Windows folder and preserve both saves before changing files.

Patch 1.035 added gamepad support to both the game and demo. Minimum disk-space figures are specifications for available install space, not the size of the Steam download; see /platforms/system-requirements/.

Questions

Can I play AETHUS in the browser?

No official web build exists. Steam, the demo page, and pawsmonaut.games only offer a download.

Does the demo save transfer?

On Windows, yes, via Steam. On Linux with Proton, players report the save does not move automatically. The Windows path is in the FAQ.
