Space Marine 2 Proton 9.0-4

The next stable Proton update is here after rigorous testing by both Valve and the community, and boy does it have a ton of changes! We have some new playable titles like Total War: SHOGUN 2, Test Drive Unlimited Solar Crown, and Disgaea 4, while making regressions to make games like I Expect You To Die and Fablecraft playable again.

There are also tons of new fixes for a multitude of games like Rivals of Aether 2, Final Fantasy 16, Yakuza 3 and 6, SpellForce 3, Diablo 4, and adding in controller support for Clash for Crust. Speaking of which, Xalia has also been updated, so we can use a controller for some new game launchers like the ones for Fallout: New Vegas, Trackmania Nations Forever, and Warriors All-Stars.

The new Proton update should download automatically when you open your Steam Deck.
