Play Bio Menace 2 (Episode Two: The Hidden Lab) Online

Game Overview

Bio Menace 2 (Episode Two: The Hidden Lab) is that classic MS-DOS side-scroller where you play as Snake Logan—basically a dude in a red jumpsuit blasting through mutant-infested labs. The first thing you notice? The controls are simple but weirdly satisfying—just running, jumping, and shooting, but with this chunky, pixelated charm.

Each level throws you into these maze-like labs full of traps (watch out for the floor spikes—they got me way too many times) and creepy monsters that pop out of vents. You’re hunting for keycards or crystal shards to unlock the exit, usually by rescuing hostages or taking down some gross boss. Though sometimes, if you’re lucky, you can just sneak past everything and bail early.

The power-ups are the best part—flamethrowers, spread shots, even temporary invincibility. I always hoarded them for the bosses, which was probably overkill, but hey, no regrets. The music’s got that crunchy synth vibe that somehow makes shooting giant rats feel epic.

It’s short, chaotic, and exactly what you’d expect from a ‘90s DOS game—no frills, just pure run-and-gun fun.

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