City of Heroes on Steam Deck

You can take the following steps instead of following City of Heroes on Linux instructions to install Homecoming: City of Heroes on your Steam Deck as the device already comes preinstalled with Wine and Proton.

Install Script

Assembled by HC Developer Faultline, just run one command in a Terminal window:

bash <(curl -s https://raw.githubusercontent.com/FaultlineHC/LinuxHC/main/hc-install.sh)

Once installed, right click on the Desktop Shortcut and pick "Add to Steam" to make the launcher available in Gaming Mode.

Notes:

• Features in graphics cards released since shutdown such as FSR (AMD requires compatible games to add support from the developer) and Ray Tracing (Game Engine doesn't have any RT features) do not apply to City of Heroes. You can turn them off to reduce CPU load.
• It is recommended to use Proton over Wine to run the game, as libraries such as dxvk are preinstalled to add a small boost to OpenGL games like City of Heroes. You can select a custom environment in the game Properties in the launcher.
• Modified components such as GE-Proton (the GloriousEggroll release of Proton) do not have any appreciable effect on running the game. All of the optimizations made on GE-Proton are aimed at newer titles.
