Play Altered Beast Online – Nintendo (NES) Game

Game Overview

Ever wanted to punch monsters as a half-man, half-werewolf? Altered Beast on the NES lets you do just that—and then some! This arcade classic, ported to the Nintendo Entertainment System, throws you into a mythic underworld where Zeus himself resurrects you to rescue his daughter. But here’s the twist: you don’t just brawl through hordes of undead freaks—you evolve. Snag glowing orbs to transform into beefed-up beasts, from a lycanthrope with claws that mean business to a dragon that breathes fire like it’s going out of style.

Sure, the controls might feel a little stiff by today’s standards, but there’s something undeniably cool about the game’s over-the-top vibe. The eerie chiptune soundtrack, the dramatic "Rise from your grave!" voice line, the sheer joy of morphing into a monster mid-fight—it’s pure ‘80s arcade magic. If you love side-scrolling beat-’em-ups with a weird, wild twist, Altered Beast is a nostalgic trip worth taking. Just don’t blame us when you start growling at the screen.
