To get the story over with: Evil wizard has captured the princess, oily muscleman carrying a huge sword tries to free her by first confronting the sorcerer's soldiers and then the evil master himself.
can be played in two modes. First, there are training fights with blokes you happen to run across in the wilderness. This part can also be played by two human players. The actual campaign for the princess is limited to one player versus the evil computer, though.
For whatever reason, you only ever have to struggle with one opponent at a time. Using various moves (triggered by joystick with mediocre responsiveness), you try to bring the enemies energy bar down to zero before your own one reaches the bottom.
Nothing really special,got famous and popular for other reasons than originality or sizzling playability. Its main attraction with kids back then was the brutality it shows. On top of the 'coolness' scale: the move which makes your character chop the opponent's head off (complete with a goblin coming in to drag the body away, kicking the severed head aside).
Also, since the fights all take place either in front of the wizard's throne or in his arena, he's always there himself. But not alone - the scantily clad princess is always there, too. This lead to demands from players for her to appear naked. One cracked version (which we're offering for the sake of hypocrisy) delivers that as well.
So, whilemight not be especially appealing for its gameplay, it's the forefather of a huge trend which would develop only many years later. These days you'll have a hard time finding a game for which there isn't a 'nude' patch, and lots of gore is always included by default anyway. Way ahead of its time (whether you interpret this in a positive or negative way is up to you), even if it looks quite tame by today's standards, of course.
