Unifideck update brings Xbox Game Pass Downloads to Steam Deck

Unifideck’s Decky plugin update lets Steam Deck users download and play Xbox PC Game Pass games directly on the handheld without a Windows workaround, Steam Deck HQ reported Nov. 9, 2026.

mubaraknumann, an IT Implementation Engineer, created Unifideck using AI. The update builds on the Xodus project started by imLinguin and Vidi0, with mubaraknumann building his own Xodus Runtime and Backend. Users sign in with an existing Microsoft account to check which Game Pass subscription they have and sync their library, then download games without logging in again.

Synced Game Pass games appear under the Microsoft tab in non-Steam games, and the plugin checks licenses before download. Users with access to Xbox Cloud streaming can choose to either stream or download a game when they try playing it. The update also includes a fallback for countries without Xbox Cloud streaming access, letting users download games they cannot stream.

Steam Deck HQ says that before the update, users logged into Microsoft to play Game Pass games via the cloud, while the new update removes the need to log in again. Steam Deck HQ’s reporter said setup was straightforward after logging into a Microsoft account and every synced Game Pass game appeared without issue. The reporter requested an icon or badge for Game Pass games confirmed not to be working or for pre-orders users cannot download yet.

The same update adds achievement popups for Epic Games, GOG, and Xbox, a Battle.net version picker, cloud saves for Linux GOG games, and Steam review scores and tags on game pages. mubaraknumann got classic Xbox games working after the reporter reported them not working, including Crimson Skies. Steam Deck HQ’s reporter described the change. “And now, it can officially recognize Xbox Game Pass games and download them for us to play.”

Unifideck is unofficial and not affiliated with Valve, Epic Games, CD Projekt / GOG, Amazon, Ubisoft, Blizzard Entertainment, GameVault, itch corp, or Microsoft, according to its GitHub page published Jan. 4, 2026. The plugin aggregates Epic Games Store, GOG, Amazon Games, Ubisoft Connect, Battle.net, GameVault, itch.io, and Xbox Cloud Gaming with Steam on Steam Deck. The plugin requires Decky Loader installed on the Steam Deck, and store sign-in and Xbox Cloud Gaming require Microsoft Edge.

Unifideck lets users install games to internal storage, an SD card, or a custom folder, and sets up a recent Proton automatically for most Windows games. Proton is a compatibility layer that lets Windows games run on Linux-based systems. The plugin shows cover images, icons, Metacritic scores, and Steam Deck compatibility ratings for non-Steam games alongside the Steam library.

Cloud saves through Unifideck currently cover Epic and GOG only, and game-level support varies. Separately, Unifideck’s Xbox Cloud Gaming support is streaming-only and depends on Microsoft Edge, according to its GitHub page.

Installation requires downloading the latest plugin ZIP from Releases, opening the Quick Access Menu, navigating to Decky Settings, enabling Developer Mode, clicking Install Plugin from ZIP, and selecting the ZIP file. The plugin replaces Steam’s default library tabs, including All Games, Installed, and Great on Deck, so some sort and filter behavior is not preserved.

Certain games still require manual Proton testing or store-specific workarounds. Users set Proton version and launch options through Steam’s native shortcut Properties, with no in-plugin picker available. Some games lack SteamGridDB artwork or complete metadata.

Users may still need to click Play via Cloud inside the xCloud home screen to finish OAuth (a sign-in standard that lets one account log into another service) after the first successful Microsoft sign-in. Users must restart after sync or cleanup for new shortcuts and artwork to fully apply. Unifideck advises choosing a Proton version before installing Ubisoft games because changing it later can invalidate the prefix and force a reinstallation.

Unifideck’s GitHub page describes a Settings Capture Logs feature that gathers all logs and state files, adds a device report, and writes a zip to Downloads. The resulting zip excludes passwords, store login tokens, and browser cookies.

Xodus Nexus is an experimental launcher that brings PC Game Pass games to Steam Deck without cloud streaming or a Windows installation. Geeky Gadgets reported on Oct. 28, 2026, and Notebookcheck reported on Oct. 23, 2026.

Users download the AppImage from GitHub, sign in with a Microsoft account, install the Nexus Runtime through settings, then download supported Game Pass titles directly through the launcher. Notebookcheck reported Oct. 23, 2026, that Xodus Nexus version 0.3.11 shipped with fixes for login issues, licensing errors, and problems launching games, after version 0.3.10 resolved login errors. “Meanwhile, version 0.3.11 has already been released, bringing additional fixes for login issues, licensing errors and problems launching games.”

Some users are concerned Xodus Nexus could violate Microsoft’s terms of service and result in account suspensions, but no confirmed cases have been reported. Notebookcheck says games relying on anti-cheat systems or extra launchers may cause problems with Xodus Nexus.

Xbox Game Pass was originally designed for Windows and Xbox platforms, which limits compatibility with Linux-based systems such as Steam Deck. Geeky Gadgets reported Oct. 28, 2026, that Xbox Game Pass includes cross-platform save functionality allowing seamless switching between Xbox consoles, PCs, and Steam in some cases, citing Halo Infinite as a supported game.

Xodus Nexus requires manual setup including runtime environments, and not all games are compatible, so users may need to consult a compatibility list. Performance varies on third-party Game Pass tools: less demanding games like Minecraft Dungeons 2 run smoothly on Steam Deck, while graphically intensive games like Avowed may experience frame rate drops.

Geeky Gadgets says some multiplayer features may face restrictions on third-party Game Pass platforms. Updates to third-party Game Pass tools often require manual reinstallation, and some official features like a dedicated library button are not fully replicated.

Steam Deck HQ says Unifideck’s Xodus components are separate from the plugin, allowing compatibility updates for more games without requiring a Unifideck reinstallation. Not every Xbox Game Pass game works with Xodus immediately, some will not work at all, but most will and run pretty decently, Steam Deck HQ reports.

Notebookcheck reports that a YouTube tutorial showed The Outer Worlds and Hollow Knight: Silksong download and launch directly through Steam Deck Gaming Mode via Xodus Nexus. Hollow Knight: Silksong is not currently on the Xodus Nexus compatibility list despite appearing to run without issues in the video. Users confirm Xbox Play Anywhere save data synchronizes through Xodus Nexus.

A player report says Neon Abyss 2 functions without issues on Xodus Nexus, with controller support, cloud saves, and Steam Deck sleep functionality. Users can download Xodus Nexus at no cost from GitHub. Setup starts in Desktop Mode with an AppImage download from GitHub and a Microsoft account sign-in. Players can use the three-dot menu to add downloaded games to their Steam library and then launch them in Gaming Mode.
