About Altered Beast (usa, Europe)
Altered Beast on the Sega Master System was a port of the arcade game, developed and published by Sega. It arrived on the 8-bit console during a time when side-scrolling action games were becoming a staple of home systems, offering a different experience from its 16-bit counterpart.
You control a resurrected warrior, moving from left to right through each stage. Your main goal is to defeat the boss waiting at the end. You fight zombies and other monsters with your fists; defeating certain glowing enemies releases blue spirit balls. Collecting three of these transforms you into a powerful beast, like a werewolf or a dragon, granting you new, stronger attacks. The game is short but challenging, with enemy placements that require quick reactions. It feels like a straightforward, muscle-powered brawl where your power-ups are temporary and crucial for survival.
