Sega Master System / Mark III / Game Gear
Catchy name for a game with some eyecatching graphics. The beast in question is a hero risen from the grave who can power up, first into a Charles Atlas body and then into a demonic, fire spitting wolfman.
Power-ups are gained by destroying certain foes, encountered on the gently scrolling levels. They come from both sides, above and even up from the ground, to be punched, kicked and zapped out of existence. End-of-level guardians are of course essential and take a hell of a lot of beating.
Not very imaginative in gameplay, but notable for its classy graphics. The wolfman, however, adds to the fun considerably, because as well as shooting fireballs he can launch himself across screen and lay waste to all who stand before him.
