Playing GOG, Epic, and Prime Games on Steam Deck

Posted on February 16, 2026 by Aywren

One exciting feature of owning a Steam Deck is that you are not locked into playing just the games you own on Steam. In fact, there are a couple ways that I know of to install and play games from other launchers including GOG, Epic Store, and Amazon Prime Games.

Heroic Launcher

The Heroic Launcher is likely the best-known free and open-source software that you can install on Steam Deck to get this job done. Note, you can also try it out on Windows, Mac, and Linux!  

As the name suggests, it looks much like any other game launcher. Once you’ve installed it, keep in mind you will need to log in through the launcher to sync your GOG, Epic, and Prime game accounts to it.

So where do you start?

You download the Heroic Launcher using the Discover software center on your Steam Deck. This is where you usually install most Linux-based software, so if you’ve ever fiddled around with installing things from Discover, you’d just search for Heroic Launcher like anything else.

If you’re new to all this – I understand! – here’s a short but detailed video I found that walks you through all the steps from downloading, installing, where to launch, and how to connect your game libraries to Heroic.

One question I had in a comment was that of the use of Proton with Heroic Launcher. The video does mention this starting at 1:30. But here’s the answer the official FAQs have on the Heroic website:

In Heroic, you can use Proton to run Windows games on Linux. You can choose which version of Proton to use for each game, and you can also download custom versions of Proton directly from the Wine Manager page inside Heroic. It is important to note that Proton was not designed to run games outside of Steam, and the results may vary. You can check for compatibility information for each game on the ProtonDB website: https://www.protondb.com

It doesn’t seem like this is saying that Heroic installs Proton for specific games, but it does allow you to select the version of Proton to use per game. So, you will still need to download and know that information. Though the video notes that you shouldn’t have to change the default Proton setting too often.

Unifideck

Another newer option to play GOG, Epic, and Prime games on the Steam Deck is a Decky Loader plugin called Unifideck. The perk with this option is that it pulls games from your other launchers into the Steam launcher automatically. Unlike Heroic, you don’t have to use a separate launcher to find and download your games.

Now this may be a positive or negative for you. I noticed that Unifideck does just what it says on the tin by pulling all games into the Steam UI. But seeing that I have hundreds of games in those other launchers, it’s inflated my Steam Deck library quite a bit, making it a little more difficult to page through all the games unless I’m specifically using organizational folders.

The other down side is that this method requires installation of not just Unifideck, but also Decky Loader. You also have to enable Developer Mode because Unifideck is not yet native to the Decky Loader downloads. So, this method requires many more technical hoops to jump through than Heroic does right now.  

However, for someone who wants everything in one place and is familiar with Decky Loader, this could be a good option. If you’re interested in learning where to start, let me point you to this video:

Please keep in mind that not every game on every launcher will run well on the Steam Deck. This is true of Steam games, and it’s true of your GOG, Epic, and Prime games as well. But the fact that you can bring everything under one handheld system is an exciting concept!

If you give it a try, I hope you find something you really enjoy for your Deck!
