Note: Before starting, check if the Steam pairs to Wi-Fi

1. Update the Steam Deck’s System

Method 1/7

The most frequent cause for startup issues with any game is an outdated version of Steam Deck’s OS. The next step is to ensure the console is up to date by manually checking for updates through the software tab within the settings.


Here’s how to check if a newer update is available for your Steam Deck:


  • Access the Steam Deck’s “Settings” and navigate to “System.”
  • Tap on “Apply” next to Software Updates to begin the process.
  • Wait until the console reboots or initiate the restart manually.

Updating the Steam Deck’s OS requires a stable connection to a Wi-Fi network. If the console fails to connect to Wi-Fi, we recommend pairing the console to your mobile’s hotspot!

2. Launch Hades 2 Via “Desktop” Mode

Method 2/7

An unfailing solution for any game refusing to launch on your Steam Deck is turning it on through “Desktop” mode on the Steam Deck. While set to “Desktop” mode, the Deck can even be used as a desktop computer or laptop with the required mouse and keyboard.


Here’s how to launch Hades 2 through “Desktop” mode on your Steam Deck:


  • Press the “Steam” button on the Deck and select “Power.”
  • Highlight and choose “Switch to Desktop” from the menu.

  • Wait until the Steam Deck loads up as a desktop device.
  • Open the Steam launcher manually and launch Hades 2.
To exit the “Desktop” mode, double-tap the “Return to Gaming Mode” icon in one of the screen’s corners and wait until the console reboots.

3. Enable “Compatibility Tool” For Hades 2

Method 3/7

Due to Hades 2’s early-access status, the game may still not be fully compatible on all platforms, including the Steam Deck. You can manually enable a compatibility tool for Hades 2 through the game’s settings, to ensure it launches without displaying errors.


Here’s how to enable Hades 2’s compatibility tools on Steam Deck:


  1. Navigate to the Steam Deck’s library and locate Hades 2.
  2. Select the cogwheel icon on the game’s launch screen.
  3. Once in the settings, press “Compatibility” on the side.
  4. Check “Force the use of a specific Steam Play compatibility tool.”
  5. After going back, apply the required compatibility update for Hades 2.
  6. Exit Hades 2’s settings and attempt to launch the game on the Deck.

Do not adjust the compatibility slider and ensure it is set to the default “Proton Experimental” option before testing Hades 2. If the game is still refusing to launch, choose an older Protocol version, such as 3.16-9 up to 6.3-8.

Tip: The compatibility tool even works for non-Steam games added to your library!

4. Restart the Steam Deck’s System

Method 4/7

A temporal fault or a non-lasting system issue may have prevented Hades 2’s launch on your Steam Deck console. A quick solution is to reboot the Deck’s system and attempt to re-launch Hades 2 after the OS has fully loaded up.


Follow these steps to restart the system of your Steam Deck in easy steps:


  • Hold the “Power” button for 4 seconds (7 seconds on the OLED Deck.)
  • Wait until the console powers off and connect it with an A/C adapter.
  • Press the “Power” button to turn on the console and test Hades 2.
