There is no native Linux version of over the hill, and the developers intend for the game to run on Steam Deck through Proton. That is a statement of intent from the official FAQ, not a published performance result. The FAQ does not give a frame rate target, a graphics preset, a battery estimate, or a Steam Deck certification status.
So the accurate answer has two halves: the platform path is Proton, and what that path will actually deliver on Deck hardware is 待确认.
No native Linux build
The official position is that a native Linux version is not being made. That is a straightforward statement about the build, and it means there will be no Linux executable to install outside Steam.
It also means the only route to the game on a Linux machine is the compatibility layer. That is a normal arrangement for Windows-first Steam titles, but it is worth being clear about which part is a decision by the developers and which part is a consequence of the compatibility layer's general limitations.
Proton on Deck is an intention, not a result
The developer statement is that they intend the game to run on Steam Deck via Proton. Intent describes a goal the team is working toward. It does not describe frame rates, resolution, settings, or how the controls behave in Deck's handheld form factor.

Reading the intention as a performance guarantee skips the part nobody has published yet. Nothing in the available material reports a verified Deck playthrough, a completed playtest on Deck hardware, or a settings recommendation for the handheld screen.
Proton support and performance are two questions
The reference material treats these as separate questions, and that separation is the most useful thing on this page. Whether the game can be launched and played through Proton is a compatibility question. Whether it performs well on Deck hardware is a performance question. A yes on the first does not answer the second.
This is why "confirmed via Proton" and "verified on Deck" appear in different places in community discussions. Both statements can be true simultaneously — the game runs through Proton, and running it well on a 7-inch screen with a handheld power budget is a separate engineering problem with its own answer.
What the FAQ does not publish
Four things a buyer would want are absent from the official material.
| Not published | Status |
|---|---|
| Frame rate target | 待确认 — no official target |
| Graphics preset for Deck | 待确认 — no recommended preset |
| Battery life estimate | 待确认 — no official estimate |
| Steam Deck Verified certification | 待确认 — status not stated |
The minimum system requirements on the Steam page do not cover this either. They are Windows-based, including Windows 10, an Intel Core i5-7400 / AMD Ryzen 5 2600, 8 GB RAM and either an Nvidia GTX 1070 or AMD Vega-56, with 4 GB available space and specs tested at Full HD resolution. Two figures vary across official language pages, with the AMD card also written as Radeon RX 5600 on some pages and storage as 2 GB on the Portuguese page — both discrepancies are unresolved, so neither number is worth planning around as definitive.
What this means for a Linux desktop user
The FAQ statement is about Steam Deck. That is a specific device, and reading it as a promise for every Linux distribution and hardware combination is a step further than the source goes.
A Deck is one machine with one screen, one power budget and one controller layout. A Linux desktop is a category covering different GPUs, different drivers and different display situations. The developers named the Deck; nobody has published a general Linux support statement.
If you run Linux and want to try the game, Proton through Steam is the available route, and it is a route the developers have said they intend to support on at least one Linux device. What your specific combination does with it remains 待确认.
Reporting compatibility problems usefully
If you do test it, the community reference recommends recording four things with any problem report. That set is what makes a report actionable rather than anecdotal.
| Record | Why it matters |
|---|---|
| Proton version | Compatibility behaviour changes between Proton builds |
| Distribution or Steam Deck system version | Separates driver issues from Proton issues |
| Game build | Distinguishes a launch-day bug from a later fix |
| Launch options | Affects how the game runs under the layer |
Recording all four separates the two failure families described above. A launch option left over from a previous game, a Proton version regression and a driver problem can look identical from the inside — a stutter or an unrecognised input — so context is what turns a report into a fixable item.
Planning a Deck session around unknowns
Given how much is unpublished, the practical approach is to plan for measurement rather than for a known target. Deck owners can reasonably expect the game to launch through Proton, and should expect to determine their own settings rather than following a published preset. Checking the frame rate cap and the upscaling options on the handheld screen is the first thing worth doing.
The PC feature list gives a sense of what may need tuning. It includes DLSS 4 and FSR 3 upscaling, HDR, a colour blind mode, and an adjustable frame rate cap from 30 to 240 FPS. On a handheld, the low end of that cap range is the more relevant figure than the top. Whether any of these behave differently under Proton is 待确认, so treat them as candidate settings rather than working defaults.
Saves on Linux
Save data is handled through Steam Cloud and Xbox Cloud. For the Linux path, the community wiki records the save location under the Steam Play compatibility data directory, using the app ID 2929250 at steamapps/compatdata/2929250/pfx/.
That path matters beyond curiosity, because cloud sync and a local file are two different things. If you ever need to recover a save or move one between machines, the compatdata path is where to look. Whether Linux and Windows saves interoperate directly is not something the available material states.
What remains unknown before release
The performance picture is 待确认 across the board. Measured Deck frame rates, recommended settings for the handheld screen, and whether the visual options listed for PC — DLSS 4, FSR 3, HDR, a colour blind mode, and an adjustable frame cap from 30 to 240 FPS — behave the same way under Proton are all unstated.
Also 待确认: the required Proton version, the Steam Deck certification status specifically, and whether any Linux distribution receives a more specific recommendation than the Deck. The developers have expressed intent and committed to no native Linux build. Everything downstream of that is open until someone measures it.
