Ashes of the Singularity II PC Specs, File Size and Steam Deck

Updated November 9, 2026: Valve has published a Steam Deck verdict for Ashes of the Singularity II, and it is Unsupported.

Steam wants a 64-bit Windows 10 or 11 machine with 50 GB of free space, and it recommends an SSD. If the price is still the open question, we compared both editions with what the Premium adds. The minimum bar is a Ryzen 5 2400G or an i5-8500 with 8 GB of RAM and an RX 580 or GTX 1660. The recommended tier doubles the memory and asks for an RTX 3070 or an RX 6750 XT. Valve rates Ashes of the Singularity II Unsupported on the Steam Deck, and the game is Windows only.

Minimum and recommended requirements

Every line of that table comes from the requirement block on Steam’s store page, and the numbers are Valve’s own. Steam lists the same 50 GB and the same SSD note in both tiers, so the difference between minimum and recommended is entirely processor, memory and graphics card.

How big is the download?

50 GB is the only number Steam publishes, and it appears as storage space, not as a download size. The store page still reads “This game is not yet available on Steam” with a planned release date of November 10, 2026, so there is no separate install-size figure and no preload date to plan around. Treat 50 GB as the space you need free on the drive, not as a download you can watch tick down tonight.

Is it coming to Steam Deck?

Valve rates it Unsupported on the Steam Deck. Its own compatibility report for the title now returns the Unsupported tier with the note “UnsupportedGraphicsPerformance”, and the separate SteamOS result for desktop Linux comes back Playable, meaning the game starts under that layer. The store page carries no Steam Deck section of its own, so the compatibility report is the only verdict on record.

Because the game ships for Windows only, any Deck play would depend on Proton, the compatibility layer Valve maintains for Windows games on Linux. ProtonDB is the community database that tracks how games behave under that layer, and it has eight player reports for Ashes of the Singularity II so far, with a bronze tier and a confidence rating of “moderate”. On an unreleased game that number tells you almost nothing about the final build, so treat it as a placeholder, not a verdict.

Is there a Mac or Linux version?

No. Steam’s platform list for Ashes of the Singularity II shows Windows and nothing else, and Stardock’s announcement names Steam and Stardock’s own store as the only places to buy it. There is no native macOS or Linux build to install, and no console version has been announced either, so the Steam Deck question above is the only way this game reaches hardware other than a PC.

Why the network line is in the requirements

Steam lists a broadband Internet connection under both tiers. The game has online PvP and co-op alongside the single-player campaign and the instant action skirmishes, so the connection requirement covers the multiplayer side of the package, such as the PvP matches and cooperative battles listed in Steam’s own feature list. The campaign itself is a single-player mode, and Steam’s feature list for the game also carries Steam Achievements and Steam Cloud.

When does it launch, and can you preload?

Steam’s store page carries a single release timestamp for the game, 9 a.m. ET on November 10, 2026 (14:00 UTC), and it applies to everyone who buys either edition. No preload has been announced, and with the page still on wishlist-only until launch, pre-download is not on offer. Our release-time guide has the unlock moment for every time zone, our report on the announcement covers the launch itself, and the game’s page on this site keeps the date and platforms in one place.

Stardock has been letting people play before the release. The publisher’s announcement refers to the Steam Next Fest demo and September’s public multiplayer playtest, and Steam’s own news feed ran that playtest from September 8 to 14, 2026. If your question is whether the game runs on your machine, that is the cheapest way to find out.

We compared the two requirement tiers on Steam’s store page side by side, and the part worth planning for is the storage line, not the graphics card. Both tiers ask for the same 50 GB of space and both carry the note that an SSD is recommended, while the jump from minimum to recommended is 8 GB of RAM, a faster CPU generation and a graphics card step up from a GTX 1660 to an RTX 3070. That leaves one number to get right before launch day, because 50 GB is the one requirement you cannot upgrade after the fact without deleting something else, and the store page gives you no separate download size or preload window to plan around.

Correction (November 9, 2026): Updated November 9, 2026: the Steam Deck verdict is now published and it is Unsupported, not unrated.
