SpaceCombat is an open source PC game. It's a single player space simulation. Similar (commercial) games were TIE Fighter and Freespace. When you liked these games, you will love SpaceCombat.
It's recommended to play the game with a joystick.

Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
