Unlock Full Potential of Steam Deck with Epic & GOG

It’s fair to say that the Steam Deck has redefined PC gaming, by making the once desktop-bound experience portable. But while you might believe that you’re limited to games in the Steam library, you’re not.

While the Steam library has a huge collection of games, some titles are only available from third party services, such as Epic Games. Meanwhile, some of your older favorites can probably be found on GOG (formerly known as “Good Old Games”).

Incredibly, both of these services can be installed. Here’s how to install titles from Epic Games and GOG on Steam Deck.

What Is Heroic Games Launcher?

Designed to allow Linux users to access the Epic Games store and the GOG.com store, Heroic Games Launcher for Steam Deck is free and open source software.

Once installed, Heroic can connect to your Epic Games and/or GOG account(s), whereupon it will find your library of games. This list can be imported, games installed as and when required, and more can be added when you feel like it, either on your main PC, in a browser, or using Heroic.

If you have games on Epic Games or GOG that you want to play on Steam Deck, Heroic is ideal.

Alternatives to Heroic Games Launcher

This guide attempts to make installing GOG games and Epic Games titles as easy as possible. However, using Heroic Games Launcher is not the only method.

Another option is to install the GOG client on Steam Deck. Unfortunately, this is a tedious process that can take up to an hour to complete.

In addition, there is an alternative called Lutris (which covers all Linux gaming options).

Heroic Games Launcher is a simpler approach that enables you to start playing games sooner, rather than later.

Before You Add Non-Steam Games to Steam Deck

Setting up Heroic Games Launcher on Steam Deck is straightforward, but there is something you might want to do first.

If you’re planning to install extra non-Steam games on Steam Deck,consider a microSD card for additional storage . A Class 10 SDXC card is best for this, including any branded for the Nintendo Switch.

This is a particularly wise idea of you opted for the cheaper 64GB Steam Deck model.

The main reason for this is that third party games can currently only be stored on the Steam Deck’s internal storage. Consequently, you’ll need to make space by moving large Steam-based games from the internal storage to the microSD card:

1. In your Library, use the controls to select the game you wish to move
2. Press theOptions button
3. SelectProperties
4. Go toInstalled Files
   
5. SelectMove install folder
6. In the Move Content screen, highlightMicroSD Card and tapMove
   
7. Wait while the process completes

This should provide more space for installing titles from other platforms. Epic Games are often quite large titles, although most games you might have acquired from GOG.com are probably comparatively modest in size.

Is It Safe to Install Non-Steam Games on Your Steam Deck?

If you’re concerned about breaking warranty or have some other reason to be concerned, don’t worry. A Steam Deck is capable of running most PC games, including those on Epic Games. You may have noticed some crossover between the Epic Games and the Steam libraries.

Epic Games has given many games away over the past few years. It’s simple to get free games from Epic Games and many gamers have grown a library of such games, preferring this to spending money on the exact same titles on Steam.

Furthermore, Steam Deck runs a special version of Arch Linux, and has a desktop mode where more games can be installed, if desired. Furthermore, the Proton compatibility layer software is regularly updated and ensures support for many Windows games.

In short, it’s completely safe to install non-Steam games on your Steam Deck.

Before proceeding, you might want to make things easier for yourself by grabbing a USB keyboard and mouse and a USB type-C hub for the Steam Deck.

While you can use the device’s on-screen keyboard (perhaps the most widely-used Steam Deck shortcut , activated withSteam + X ), it is far easier to sign in to Epic Games with a physical keyboard.

Otherwise, you’ll be using the right-hand touchpad as a laptop touchpad to control the mouse pointer on your Steam Deck.
