Grand Theft Auto: San Andreas — Open Multiplayer

Uses your legitimate copy of GTA:SA from Steam. Make sure you have installed the Steam's version first.
You will need to download these mods manually:

This installer tries to preserve the original feel while fixing issues with the game on modern hardware.
If you experience issues (for example, crashing game when paused), consider trying to change the runner to Proton.
The GUI OpenMP launcher is not working, but the command line option is working properly, you can create multiple duplicates of the Game and change the command line parameters to join different servers.
This installer is designed for Steam Deck, but should work for any popular Linux distro as well. If you need to get the Steam Deck's joystick buttons to work, you will need to create a shortcut for Steam from Lutris and launch the game from Steam's Game Mode.
