Altered Beast

Developer: Sega

Altered Beast on the Sega Master System delivers a compact, punch-heavy arcade experience where you play a resurrected warrior who transforms into savage beasts as you collect spirit balls. Levels mix side-scrolling platforming with close-quarters beat 'em up combat, tight enemy patterns and memorable boss encounters. The game leans on escalating powerups and short, intense stages that reward timing and pattern recognition rather than exploration. Its chunky visuals and booming soundtrack capture late-80s arcade nostalgia while a steady difficulty curve challenges players to master transforms and survive gauntlet-like fights for repeated high-score runs.
