Warhammer 40,000: Dakka Squadron Proton Experimental

There was a new Proton Experimental update earlier today with some new playable games and fixes. We can now play Warhammer: Dark Omen (Classic) and Portal Worlds, while there was a fix for Forza Horizon 6 closing after suspending/resuming the game. There were also regression fixes for Homeworld 2 Classic and SHOGUN: Total War, and the audio distortion in the intro video for Warhammer 40,000: Dakka Squadron Flyboyz Edition has been fixed.

The new update should automatically download if you already have the experimental layer. If not, just search for Proton Experimental in the Steam store on your Steam Deck and download.

  • Now playable: Warhammer: Dark Omen (Classic), Portal Worlds.
