I played Sword of Sodan on my Genesis, and man... it was horrible. I was also horrified to learn this came from the Amiga. So I guess the object of that version is identical - stab everyone in the crotch till they die while wrestling unresponsive controls.
Also learned Dark Castle has a port to Amiga too, Genesis version was horrible too, controls, sound and everything else just blows. I guess the Amiga version is probably the same too.
