Altered Beast is a game from back when I was a kid. Yes, they did have games back that, it was made out rocks with it being the stone ages and all. It came out in 1988 and was launched as an arcade fighting game by Sega.
The game is set in Ancient Greece, and follows a centurion who is resurrected by Zeus to rescue his daughter Athena, and to do so becomes able to turn into beasts such as the werewolf with the use of power-ups. So...totally plausible and all that LOL
After being launched for arcades it was later released for home consoles and computers.
A Roman centurion who had died in battle is resurrected from the dead by Zeus. The centurion is ordered by Zeus to save his daughter Athena from a Demon God called Neff in the Underworld. To become able to withstand the perils, the warrior gets the ability to collect three spirit balls on each level, the last of which transforms him into a human/beast hybrid of formidable power.After a series of battles in a journey that ends in Dis, the centurion finally defeats Neff and rescues Athena. In the original arcade game, the end credits are interspersed with images of actors in costumes for the different characters and monsters of the game, implying the whole game was a film production.
You can now play Altered Beast on the iPad, and the Nintendo 3DS.
