Rise from your grave ! Altered Beast is a famous Sega beat 'em up arcade game released in 1988. The player controls a centurion - 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 (orbs). If the player picks up an orb, he will begin his transformation from human into 'Beast'. Once 3 orbs have been collected, the transformation is complete. After the boss fight, the player reverts to human form. This is the arcade version, but Altered Beast was a pack-in game for the Sega Genesis / Sega Mega Drive system at launch time.
