Unifideck, a Decky Loader plugin for the Steam Deck, has been released in version v0.8.0.
The tool consolidates game libraries from Steam, Epic Games, GOG, Ubisoft, Amazon, Xbox Cloud Gaming and Battle.net into a single interface.
The headline addition is experimental support for Xbox PC games, including achievements, offline play and cloud saves. Game pages now use Steam’s own layout, and the release adds achievement popups for Epic, GOG and Xbox, cloud saves for native GOG Linux games and a built-in player for Xbox Cloud Gaming instead of Edge.
New Features
- Added Xbox PC games (experimental). Install and play the PC games you own on Xbox or through PC Game Pass, with achievements, offline play and cloud saves. You can turn it on and sign in from Unifideck’s settings.
- UI Update: Game pages now use Steam’s own layout and UI, including the download bar, cloud play and achievements.
- Added Steam-style achievement popups for Epic, GOG and Xbox games. GOG achievements are tracked faster with Comet v0.4.1 bump.
- Added a version picker for Battle.net games with more than one edition installed on the same shortcut.
- Changed Xbox Cloud Gaming to play streams in Unifideck’s own player instead of via Edge. The Microsoft Edge Flatpak is now replaced by a built-in browser.
- Added Xbox Cloud Gaming for accounts without Game Pass. Free-to-play streams such as Fortnite now sync.
- Added cloud saves for native Linux GOG games.
- Added a prompt to claim an itch.io bundle game before installing it, with a button that opens the claim page.
- Added Steam review scores and tags to game pages.
- Improved download time estimates so they no longer jump around as often with unstable speeds.
