Steam Deck: What Valve's Status Actually Says
Short answer: Valve lists the game as Unsupported on Steam Deck, citing graphics performance. That is not proof it cannot run, but it is not verified either - and the developers said they had not tested it.
The official status
| Source | Status | Detail |
|---|---|---|
| Steam store | Unsupported | Compatibility note: graphics performance |
| ProtonDB | Unsupported, no reports at our check | Community Linux/Deck tracking |
| Developer | Not tested | Pre-launch answer in the official Steam discussions |
Before launch, a player asked directly whether the game would be playable on Steam Deck. The studio answered that they had not tested it and were not sure it would play properly. Valve's store label later marked it Unsupported for graphics performance.
What players report anyway
- One player reports the game running on Linux at high frame rates, so the underlying build is not blocked on the platform.
- A Steam Deck OLED performance video exists, showing the game running on the handheld.
- Steam's own review cohorts show a "played mostly on Steam Deck" group - meaning some players do use it there.
How to give it the best chance
- Update to Patch 1.0.5 or newer - it added AMD FSR upscaling and FSR 2X frame generation.
- Lower the game's graphics settings and enable FSR; frame generation helps most on supported hardware.
- Expect compromises: Valve's rating is about the experience, not about the game refusing to launch.
