Game Introduction

You have been raised from the grave according to the digitized speech at the beginning by Zeus to rescue his daughter from an evil, bald magician. Fight various types of nasties and end-of-level bosses along the way. At the end of each level, "evil baldy" appears and takes your power-ups away. The scoundrel also turns the daughter into a pigeon or something.

Level two features head suckers that can be shaken off by moving the joystick left and right quickly very difficult to work out if you don't know the game. Kill the flashing white wolves to reveal power-ups. As you collect more power-ups you gain more muscles are these steroids? and eventually you will transform into a beast -- a different one each level. These beasts are: a werewolf, a flying weredragon, a werebear, a weretiger and finally the Golden Werewolf. After the evil magician has been defeated on the fifth level, Zeus' daughter will appear as a bird and then change back to her normal self again. After that, the game ends.
