Play Swamp Thing (prototype) Online
You lumber through murky labs as Swamp Thing, ripping through mutants with vine whips that crack like wet ropes—health regenerates when you stand in those gross green puddles. The whole thing’s janky in that way Genesis games just *were*, but chucking logs at panicking scientists never gets old.

Swamp Thing for the Genesis was a prototype that never saw a full release, developed by Equilibrium and planned for publication by THQ. It exists as a curious artifact from the platform's library, a time when comic book adaptations were plentiful and often experimental in their approach to translating panel to pixel.
You control the titular Swamp Thing, moving through side-scrolling environments to combat scientists and mutated creatures. Your primary attacks involve using vine whips to strike enemies and hurling heavy objects like logs for more powerful, albeit slower, projectiles. Health regenerates when you stand in specific swampy patches, a mechanic that encourages tactical positioning during fights. The pacing is deliberate, with some awkward platforming and enemy patterns that demand patience. It feels like a rough but earnest attempt to capture the character's strength and connection to his environment.
