Play Altered Beast on Msdos Online

Game Overview

Altered Beast on MS-DOS is one of those classic arcade beat 'em ups that feels both ridiculous and awesome at the same time. You play as a resurrected Roman centurion—because of course Zeus needs a dead guy to save his daughter—and you punch your way through zombies, demons, and some truly bizarre creatures. The best part? You collect these floating orbs that slowly transform you into different beast forms, like a werewolf or a thunder-breathing dragon. The first time I turned into a werewolf mid-fight, I just started mashing buttons to see what crazy attacks I had.

The levels are short but packed with weird enemies—giant leeches, turtle-snail hybrids, even unicorn men (yes, really). And the bosses? They’re just as wild, like a rhino-man hybrid for the final showdown. The animations between levels are these cheesy little cutscenes showing Athena in distress, which just adds to the over-the-top vibe. It’s not the deepest game, but there’s something satisfying about wrecking everything as a half-human, half-beast monstrosity. Just don’t expect it to be easy—those old-school arcade roots mean you’ll die a lot before you figure out the timing.

Fun fact: This was originally a Sega Genesis pack-in game before Sonic took over. You can definitely tell it’s from the late '80s, but that’s part of the charm. If you’re into retro beat ‘em ups with a weird mythology twist, this one’s worth a play.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
