Star Saber is a single-player Galaga clone where the player's space ship sits at the bottom of the screen and shoots aliens as they swoop down the screen and attack.
There's a detailed backstory to this game involving a pilot who comes across a colony that has been destroyed by an unknown aggressor. The pilot's ship is also destroyed leaving them alone amid the ruins during which time they research the enemy so later, when they are rescued, they are able to assist in developing effective weapons. So, in a small but well armed ship in dark space a lone star pilot waits. They are the last hope, all that stands between humanity and oblivion.
The game is keyboard controlled and the action keys can be redefined. The game comes with a level editor of sorts, there are instructions on how to use a text editor, such as Notepad, to alter the game's configuration files to tweak the game and even to introduce new enemies, weapons, levels and formations.
