After recently pushing out a pretty big update to Steam Play with Proton 4.11, Valve have now added some additional titles to their Whitelist.
What is the Whitelist? Currently, this is the list Valve have accepted to be shown as a Windows game you can install in the Linux Steam client, without enabling Steam Play on your entire library. They are also set to a specific version of Proton by Valve, to hopefully give the best experience.
The new titles added yesterday were:
- APE OUT
- CivCity: Rome
- Cube Escape: Paradox
- DX-Ball 2: 20th Anniversary Edition
- Delicious! Pretty Girls Mahjong Solitaire
- DuckTales: Remastered
- Fallout 2
- Glass Masquerade 2: Illusions
- Heat Signature
- Katana ZERO
- Koi-Koi Japan [Hanafuda playing cards]
- Lovers of Aether
- Mighty Switch Force! Hose It Down!
- My Friend Pedro
- Otaku's Adventure
- Outlast 2
- Quell Memento
- Quell Reflect
- Quell Zen
- Sam & Max Hit the Road
- Shin Samurai Jazz
- Solitaire. Dragon Light
- Space Invaders Extreme
- The Messenger
They did also add some special configuration options for GRID, METAL GEAR RISING: REVENGEANCE, QUAKE Mission Pack 1: Scourge of Armagon and QUAKE Mission Pack 2: Dissolution of Eternity. Even though GRID and the Metal Gear game are not whitelisted yet.
Valve don't seem to have a public list anywhere I could see, but thankfully SteamDB are tracking it here, which shows the above and all others previously added. There's now about 168 titles in the whitelist.
This is likely the list Valve will use to eventually show Steam Play on the store pages for games, how they do that though we have no idea as they haven't talked about it lately. In the original Steam Play announcement, Valve simply said "whitelisted games will not be offered for purchase or marked as supported on Linux on the Store during the initial Beta period".
