Slordax: The Unknown Enemy

Legends tell of a race of super beings, the Slordax, who once tried to conquer the galaxy. The war lasted for a century. In the end, the Slordax were repelled. The Slordian system was dead for over seven hundred years. But now the Slordax are back. The Intergalactic Defense Alliance gave you the task to take them out with your RedDog Adaptive Strike Ship before they grow too strong to defeat.

Slordax is a rather typical shoot-'em-up vertical scroller with EGA graphics and five levels. An unique feature is the ability to control how fast the screen scrolls.
