HELLDIVERS 2 Steam Deck

A new Proton Experimental update was released yesterday with some nice fixes across the board for different games. Assassin's Creed Shadows and BattleBit Remastered are playable again, while Crimson Desert and Resident Evil 2 shouldn't have any issues with their screens. Helldivers 2 and Rocket League have also both been fixed, while The King of Fighters XIII Global Match won't leak memory.

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.
