Altered Beast
Unleash the metamorphic power. "Awaken, dead warrior!" cries Zeus, god of thunder. And you rise. You are called to live again, kicking, punching, grabbing and tearing the inhuman and monstrous flesh of terrible, dangerous minions of the underworld who would do you wrong. You are hell-bent on saving Athena, daughter of Zeus, from the demon god Neff, and sneak through the bowels of Hades and beyond. What you are now, you will be no more. You are the Changed Beast - endowed with five mighty powers of transformation, each more cruel and overwhelming than the last. By fighting, conquering and capturing spirit balls, your transformation powers will grow. But to what end? The final confrontation. Your triumph over crocodile worms, hammer demons, and tomb masters brings forth the terror of Neff himself. But boldness and cunning will be rewarded - in the ultimate Altered Beast! Transformation is the ultimate power.
Story
A Roman centurion who had fallen in battle is raised from the dead by Zeus. The centurion receives a mission from Zeus to save his daughter Athena from a demon god named Neff in the underworld. To withstand the dangers, the warrior gets the ability to absorb spirit orbs that transform him into an altered beast, a half-animal, half-human creature of immense power. Between each level there are small animations that give the player glimpses of Athena's dangers. First, he travels through the graveyard, fighting his way past zombies and winged demons. The centurion transforms into a werewolf to fight Neff in the form of Aggar. The centurion defeats him, but Neff escapes. The centurion travels through the underworld, where he fights giant leeches, Chinese rattlesnakes with dragon heads, and fierce chicken stingers (which resemble those from Golden Axe). The centurion transforms into a humanoid thunder dragon to fight Neff in the form of Octeyes. The centurion defeats him, but Neff escapes. The Centurion travels through the Cave of Souls, where he fights cave needles (which resemble giant ants), turtle-snail hybrids, and zombies called Grave Masters. The centurion transforms into a humanoid bear to fight Neff in the form of Mouldy Snail. The centurion defeats him, but Neff escapes. The Centurion arrives at Neff's palace, where he fights his way through zombies, chicken stabbers and hammer demons. The centurion transforms into a humanoid tiger to fight Neff in the form of the crocodile worm. The centurion defeats him, but Neff escapes. After the centurion arrives in Dis, he fights his way through winged demons, goat men, boar men, sawfish and purple unicorn men to get to Neff. When the centurion confronts Neff, the centurion turns into a golden werewolf while Neff turns into a rhino man. After he is defeated, a blue bird comes out of the ground and transforms back into Athena. She is then shown hugging her lycanthrope hero and thanking him for saving her. In the original game, the credits are punctuated with images of actors in costumes for the various characters and monsters in the game, suggesting that the entire game was a movie production.[2]
