A source port has been released for the 1998 FPS SiN by Ritual Entertainment. I tried it out last night and it seems to work pretty well. Features include:
- A new Linux port
- Better resolution support
- Controller Support
- Weapon radial menu
- Gamepad-friendly virtual keyboard
- Better menu/interface scaling
You can read more about the port here. The port requires the original files to so you’ll have to pick it up on Steam or GOG if you don’t own the game.
