Altered Beast is a 1988 beat ’em up arcade video game developed and manufactured by Sega. The game is set in Ancient Greece and follows a player character chosen by Zeus to rescue his daughter Athena from the demonic ruler of the underworld, Neff. Through the use of power-ups, the player character can assume the form of different magical beasts (wolf, dragon, bear, tiger, and golden wolf). It was ported to several home video game consoles and home computers. It was the pack-in game for the Sega Genesis when that system launched in 1988. Gameplay: Altered Beast is a side scrolling beat ’em up game with light platform elements. It has five levels and can be played by up to two players simultaneously. Combat takes place across five levels set in Ancient Greece and populated by aggressive undead creatures and monsters resembling those from Greek mythology. The demonic god Neff, waits at the end of each level. Between each level are small animations giving the player glimpses of Athena’s peril. Players can punch, kick and jump. The game’s premise is that Neff, ruler of the underworld, captures the goddess Athena. Angry, her father, the Olympian god Zeus, decides to choose a champion to save her. Respecting the bravery of Roman Centurions, Zeus resurrects one of them and empowers him as a champion. The game’s player character is the resurrected Roman Centurion, given extra power by Zeus so they can battle Neff and his supernatural minions.
