Altered Beast

Developer: Sega

Altered Beast is a punchy arcade beat 'em up where you play a resurrected warrior summoned by Zeus to rescue his daughter. Progressing through mythic, side-scrolling stages, you collect glowing power-ups (orbs) to transform into powerful beasts — werewolf, dragon, bear — each with distinct attacks and burst damage. Combat centers on timing combos, environmental hazards, and ritual boss fights that demand pattern reading and meter management. Its simple controls, escalating difficulty and memorable voice samples deliver pure late‑80s arcade nostalgia, rewarding persistence and learning as each stage tests reflexes and strategic use of your beast forms.
