Key Highlights:
- Batman: Arkham Asylum Game of the Year Edition is now officially Steam Deck Verified following a new Valve test.
- Valve tested the same 2015 game build that previously received an Unsupported rating, with no evidence of a new Rocksteady patch.
- Arkham Asylum now joins Arkham City and Arkham Knight, making the entire Rocksteady trilogy Steam Deck Verified.
Seventeen years after the original release, Batman: Arkham Asylum has finally earned Valve’s Steam Deck Verified badge, giving Rocksteady’s first Arkham game official compatibility with the handheld.
The change applies to the Batman: Arkham Asylum Game of the Year Edition on Steam, which contains the original game alongside the Crime Alley, Scarecrow Nightmare, Totally Insane and Nocturnal Hunter Challenge Maps.
Valve’s latest compatibility test was carried out on 16 September 2026. Arkham Asylum passed the checks for Steam Deck controller icons, legible interface text and acceptable performance using the default graphics configuration, while Valve also confirms that it now runs successfully through SteamOS.
There is one minor caveat. An external Bluetooth or USB controller may not automatically become the active controller when playing on Steam Deck, requiring players to switch it manually through the Quick Access Menu. That does not prevent the game receiving the full Verified rating.
What makes the change particularly interesting is that Rocksteady does not appear to have updated Arkham Asylum to achieve it.
SteamDB records Valve’s previous Steam Deck test from February 2022 as Unsupported, with the game tested against Build ID 597963. The new September 2026 Verified result was carried out against that exact same Build ID.
That public build dates all the way back to 22 April 2015, according to SteamDB’s depot records. There is therefore no evidence that a new Arkham Asylum executable or gameplay patch suddenly made the game Deck-compatible in 2026.
I think that is far more interesting than calling this a surprise 17-year-late game update. Valve once considered this exact build unsupported on Steam Deck, but four years later the same software now passes its Verified testing. Changes to SteamOS, Proton or Valve’s compatibility environment could explain the difference, but neither Valve nor WB Games has publicly identified the specific reason.
Arkham Asylum also completes something that was not true when the Steam Deck originally launched: all three games in Rocksteady’s main Batman: Arkham trilogy are now Verified.
Batman: Arkham Knight has carried Valve’s Verified rating since a test conducted in September 2023. Batman: Arkham City Game of the Year Edition then received its own green checkmark during 2026, with Steam Deck HQ reporting its upgrade in June and Valve subsequently retesting it again in August.
That gives the current Steam Arkham Collection a clean handheld compatibility line-up:
| Game | Current Steam Deck status |
|---|---|
| Batman: Arkham Asylum GOTY | Verified |
| Batman: Arkham City GOTY | Verified |
| Batman: Arkham Knight | Verified |
The Batman Arkham trilogy was among the legacy games discounted before the Xbox 360 Marketplace closed, and its PC collection now has another longevity boost with all three Rocksteady games officially supported on Valve’s handheld.
There is one notable exception elsewhere in the series. Batman: Arkham Origins, developed primarily by WB Games Montréal rather than Rocksteady, remains Unsupported on Steam Deck following another Valve test on 31 August 2026. Valve currently says it is still working on support for that game through SteamOS.
The original Arkham Asylum Steam situation is particularly unusual because its new status is not really a “feature” added to the game at all. The software appears unchanged. What has changed is Valve’s assessment of whether that old Windows build can now deliver a suitable out-of-the-box experience on Steam Deck.
Rocksteady’s future is less concrete. Reporting dating back to 2025 says the London studio is looking to return to Batman with another single-player game following Suicide Squad: Kill the Justice League, but Warner Bros. and Rocksteady have still not officially announced the project. Claims that it is specifically a fourth Arkham game therefore go further than the available evidence, while separate Batman Beyond rumours circulated in 2026 were subsequently dismissed by Bloomberg reporter Jason Schreier.
For anyone simply wanting to revisit where Rocksteady’s Batman series began, however, the position is much clearer. Arkham Asylum can now sit alongside Arkham City and Arkham Knight with Valve’s green Verified badge rather than an Unsupported warning.
