About Altered Beast
I first played Altered Beast on the Nintendo Entertainment System in 1990, a port of the SEGA arcade game. It was a time when side scrolling beat 'em ups were common, and this one stood out with its mythological theme. SEGA published it, and it felt like a direct attempt to bring their arcade hit home, even if the transition to the NES wasn't always perfect.
You control a centurion resurrected by Zeus to rescue his daughter Athena. You walk from left to right, punching and kicking your way through zombies, wolves, and other creatures. The main objective is to defeat the boss at the end of each stage. The signature mechanic is finding a special power up, a white wolf head, that triggers a transformation. After collecting three, your character morphs into a powerful beast like a werewolf or a dragon, gaining new, stronger attacks. The game is short but difficult, with enemy patterns you need to learn quickly. Playing it feels like a brief, challenging burst of mythological power fantasy.
