Play Bio Menace 3 (Episode Three Master Cain) Online

Bio Menace 3 is that classic MS-DOS side-scroller where you play as Snake Logan, blasting through mutant-infested corridors with a satisfyingly chunky pistol. The first thing you’ll notice is how fast Snake moves—dodging spikes and acid pits feels just right, though sometimes you’ll misjudge a jump and faceplant into a wall of teeth (happens to the best of us).

Each level throws weird little puzzles at you—like rescuing hostages trapped in goo or hunting down keycards guarded by some truly ugly bosses. There’s this one sewer level where the exit just lets you skip everything if you’re sneaky, which feels like cheating but hey, I’m not complaining. The weapons are ridiculous in the best way—flamethrowers, grenades, even a boomerang that somehow sets things on fire. Just don’t get too attached to them, because dying sends you back to basics.

It’s got that old-school charm where the difficulty spikes randomly, but nailing a perfect run feels amazing. The soundtrack’s all crunchy synth beats that somehow make shooting giant worms even more satisfying. If you’re into ’90s action-platformers with a side of cheese, this one’s a blast.

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