Altered Beast

Developer: Sega

Altered Beast on the Sega Mega Drive is a pulpy, side-scrolling action classic that blends beat ’em up brawling with light platforming. Players fight through mythic levels, collecting glowing power orbs to fill a meter and trigger iconic transformations into werewolves and other beasts, each granting brutal new attacks. Encounters ramp up in difficulty with tough minibosses, environmental hazards, and larger-than-life bosses that demand pattern recognition and timing. Rooted in its arcade DNA, the game delivers chunky sprites, punchy sound design, and a relentless, nostalgic challenge that rewards memorization and aggressive play.
