How To Play Fortnite xCloud With Decky Loader On The Steam Deck

While there are workarounds, playing Fortnite on the Steam Deck can be troublesome. There are complex lines of code to change in Desktop Mode, it’s easy to make a mistake, and manually updating Proton can make it tricky. Thankfully, with the Decky Loader program and the NonSteamLaunchers app created by GitHub user Moraroy, users can add Fortnite to their Gaming Library via the xCloud service.

The NonSteamLaunchers app does all the hard work for you by installing the latest versions of Proton on the Steam Deck via updates – so the controls work out of the box – and adds non-Steam launchers to your Steam Deck’s Gaming Mode alongside your official games and apps. Here’s a rundown on how to install Decky Loader, access its Testing Mode, and add Fortnite to your Steam Deck games library.
