First, turn on your Steam Deck, press the Steam button and scroll down Powerpress A, then select Switch to desktop.
From here, click on the little blue shopping bag icon on your taskbar. This will open the Explore menu, which is where you’ll find shortcuts to installers for all sorts of apps. Right now, we are here for a web browser. So click Internet, Later Web browser, and scroll down until you find Google Chrome or Firefox and install whichever you prefer. Once it is installed, click Launch up in the top right corner.
Step 1: Install Battle.net Launcher
Microsoft through Jaina Gray
Using your favorite Steam Deck web browser, in the search bar, type download.battle.netand download the Battle.Net Installer. Make sure you put it somewhere where you can easily find it, such as Downloads or your Desktop. Next, open dolphin (Steam Deck’s File Explorer) and navigate to wherever you downloaded the Battle.Net Installer. Using the trackpad, move your cursor over the Battle.Net Installer, then drag the left trigger on your Steam Deck (this works like a right click), then move your cursor down Add steam and drag the trigger button to the right (this function is same as left click).
Step 2: Set up Compatibility Mode
Microsoft through Jaina Gray
Now open Steam from your Desktop, navigate to Battle.net Installer, and click it. From Play menu, hover over the little gear icon and click it, then go down Property. Here we want to go to compatibilityand click the check mark for Compatible force. Then from the drop down box select experimental protons. Then X out of this menu, go back to Battle.net Installer’s play menu and press play!
Step 3: Install Diablo IV
Microsoft through Jaina Gray
From here, just log into Battle.net and download Diablo IV just like you do on desktop. After it is installed, switch back to Steam deck mode, and launch your Battle.net Launcher. (It will still say Battle.net Installer, but it functions the same as Battle.net Launcher on desktop), select Diablo IVand go save for the day!
Or do what I’m doing and wander around, avoiding the main story at all costs and taking in the sight (blood) and sound (blood) of Sanctuary!
