Play Swamp Thing on GB Online

Swamp Thing on the Game Boy came out in 1992 from Imagineering Inc. It was one of those many licensed games from the era, based on the DC Comics character, and it fit right in with the platform's library of side-scrolling action titles. You didn't hear a lot of buzz about it at the time, but it had its own little corner on the system.

You control the Swamp Thing himself, moving through levels that represent different biomes like a forest or a lab. Your main goal is to defeat enemies and clear areas of toxic waste, all while a swamp meter constantly depletes, adding a persistent time pressure. You attack with a boomerang-like vine projectile that returns to you; if you're not careful, it can hit you on the way back. You also flip turtles on their backs to use them as platforms. The pacing is deliberate, and the difficulty comes from managing your dwindling life force while navigating environmental hazards. It feels like a constant, tense struggle against the clock and your own attacks.
