ENDLESS Legend 2 on Steam Deck
Short answer
On the Steam store page for ENDLESS Legend 2 the Steam Deck Compatibility field reads "Verified" — Valve's own compatibility level, checked 2026-09-18 on the 1.0 build. That is the current, first-party answer to the compatibility question, and it is the answer that matters if you are about to buy.
There is a second, more detailed answer from a Deck specialist outlet that disagrees in tone, and understanding why is the useful part of this page.
Two verdicts, two different questions
| Source | Verdict | Build it describes | What it actually measures |
|---|---|---|---|
| Valve, via the Steam store page | Verified | 1.0, checked 2026-09-18 | Whether the game is comfortable to play on Deck out of the box: readable text, working controls, no manual configuration required |
| SteamDeckHQ, specialist review | Playable, with a build score of 3/5 and a content score of 4/5 | Early Access, reviewed 2025-09-18 | How it actually runs: frame rate, comfort, options — a performance verdict, not a comfort verdict |
Swipe the table sideways to read every column
Valve's badge is not a performance promise. "Verified" means the game passes Valve's checks for controller support, legible text and default-settings playability. It does not mean the frame rate is high, and it is not a statement about late-game turns. A game can be Verified and still run at a modest frame rate. That is exactly the situation described by the Early Access measurement below.
What was actually measured, on which build
The only detailed performance figures this site could find come from a review written during Early Access in September 2025, and they describe the Early Access build. They are reproduced here because they are the only measurements available, and they are labelled because they are not measurements of 1.0:
| Situation | Measured result | Build |
|---|---|---|
| At game start | A 25 FPS lock | Early Access |
| Late-game save (turn 144), zoomed in | Around 20 FPS | Early Access |
| Late-game save (turn 144), zoomed out | 16–18 FPS | Early Access |
| Same save, desktop build at lowest settings, zoomed out | 30 FPS | Early Access |
The reviewer's own conclusion was that the frame rate made playing on the Deck harder, while the controller support was good enough that they still preferred the Deck build over the faster desktop build because the visuals and comfort were better.
The current-build frame rate is not published here. No 1.0-era Deck measurement exists in the sources this site could read. Between that Early Access review and 1.0 the game received a rebuilt interface, a district cost rework and a large number of balance changes, and the store page's verdict moved to Verified, so the 2025 numbers should be treated as history rather than as an expectation. If a frame rate figure matters to your decision, the honest position is that this site does not have a 1.0 figure to give you.
Why you cannot see the graphics options — and the workaround
This is the single most useful finding on this page. In the Early Access review, the Steam Deck build had no video settings menu at all. The reviewer discovered that adding the launch option
```
SteamDeck=0 %command%
```
revealed the full video options — which is the evidence that the studio ships a separate Steam Deck-specific build with the graphical options locked off, rather than the settings being missing or broken. Turning those settings to their lowest on the desktop build produced the 30 FPS figure above.
The trade-off is real: the build that exposes the video settings does not have gamepad support, so you play it with keyboard and mouse. On a Deck that means either the comfortable build with locked settings, or the tunable build without proper controls. The reviewer chose the locked-settings build.
Two cautions before you try it. First, this was observed on the Early Access build; whether the 1.0 Deck build still locks the video options is not confirmed by any source read here. Second, a launch option is a workaround rather than a supported setting, and it changes which build the game loads.
Controls: the part that works well
Controller support is the strongest documented part of the Deck experience, and it is also what Valve's Verified badge independently confirms.
- Gamepad prompts from first boot, with a radial menu covering the frequently used screens, including the heroes circle and the technology tree, reachable through a combination of the D-pad and the stick.
- Steam lists Full Controller Support, with Xbox controllers, PlayStation controllers and the Steam Input API all named.
- 16:10 resolutions are supported, which matters on a Deck screen, and cloud saves are supported, so a Deck session and a desktop session can share a save.
- Steam lists 12 accessibility features for the game: adjustable difficulty, save anytime, adjustable text size, subtitle options, colour alternatives, camera comfort, custom volume controls, stereo and surround sound, playable without quick-time events, a mouse-only option, and playable at your own pace.
- There are no HDR settings.
What to do with all of this
- If you are buying for the Deck: the compatibility question is settled — it is Verified, currently. The performance question is not settled by anything this site can cite for 1.0.
- If you already own it and the frame rate bothers you: the video settings are the first thing to look for, and if your build does not show them, the launch option above is the documented reason why.
- If the controller matters more than the frame rate: that is the trade the specialist reviewer made, and it is a legitimate one.
- If you want a current number before buying: nobody in the sources read here has published one. A page that guessed would be worse than this one.
