The Diablo 4 Steam Deck Needs Windows 10 is a portable gaming powerhouse equipped with a 7-inch touchscreen display, a Ryzen 7 4800U processor, and 16GB of RAM. Running on SteamOS 3.0, it provides access to an extensive collection of games from the Steam library. However, for titles like Diablo IV, playing directly on the Steam Deck isn’t an option. Why? Because Diablo IV is exclusive to the Battle.net launcher and unlikely to make its way to platforms like Steam or the Epic Games Store.
So, what can you do if you own a Steam Deck and are eager to dive into Diablo IV? Fortunately, there’s a workaround to enjoy non-Steam games on this versatile device. Keep reading to discover how to make it happen!

Diablo 4 Steam Deck Needs Windows 10 – The easy way
At launch, the only way to play Diablo 4 on PC or the Steam Deck was via Blizzard’s Battle.net client. While this is possible on the Steam Deck, as of October 17, 2023, Diablo 4 will be available on Steam and officially Deck Verified.
For new players, this is fantastic news—just purchase it on Steam, and it’ll run seamlessly on the Steam Deck without any extra setup.
Existing players, however, will need to purchase a new copy on Steam to take advantage of this, as there’s currently no option to transfer licenses between platforms. Personally, I wouldn’t suggest buying the same game twice on the same platform just for a different store experience—but hey, it’s your call.
If you already own Diablo 4 through Battle.net, it’s better to set it up on your Steam Deck instead. I recommend using the Lutris method outlined below.
