More games! Here's all that's coming to Prime Gaming in September 2025. An easy way to add more games to your library across Linux, SteamOS and Steam Deck.
I'll use the Steam Deck Rating from Valve (
Verified, 
Playable, 
Unsupported and 
Not Rated), plus the ProtonDB rating to help you decide on what to play. Compatibility may be slightly different since the games are from various stores. Some of the games might also have no ratings right now. If a game is Steam Deck Playable / Verified it will be SteamOS Compatible.
Newly added yesterday includes: Dungeons & Dragons: Ravenloft Series [GOG Code], Into The Breach [Epic Games Store], Sid Meier’s Civilization IV®: The Complete Edition [GOG Code].
Through the rest of the month they'll also be adding: Afterimage [Amazon Games App], Spelljammer: Pirates of Realmspace [GOG Code], Tower of Time [GOG Code], Subterrain: Mines of Titan [Amazon Games App], Residual [GOG Code], FATE: The Cursed King [GOG Code], Mystical Riddles: Ghostly Park Collector’s Edition [Legacy Games Code] and Pixel Cafe [Amazon Games App].
You can install games from Epic, GOG and Amazon easily via tools like the Heroic Games Launcher and Lutris with Prime giving you a code for each game for whatever store it's on. For any games that use anti-cheat be sure to check out our anti-cheat compatibility page to see their status.
Below is the list of all titles available as of right now. The table is sorted by the End date with those ending soon at the top.
