Swamp Thing is a platform video game for the NES and Game Boy. Based on the animated series of the same name, it was published by THQ and released December 1992.
The NES version of Swamp Thing borrows the game engine from The Simpsons: Bart vs. the Space Mutants. Its introduction features the origin story of Swamp Thing and as depicted in the 1991 animated series. The player takes the role of the title character battling foes throughout the Louisiana swamps and other locations in a side-scrolling format. Swamp Thing's attack methods include punching and firing "sludge balls" which are acquired throughout the game. The player must venture through various stages, which include a graveyard, chemical factory, toxic dump, and finally, Arcane's lab. Bosses include Arcane's Un-Men, Dr. Deemo, Weedkiller, Skinman, and finally, Arcane himself.
In Game Boy's Swamp Thing, stages include the Arctic, the desert, and contaminated rainforests. Swamp Thing also uses tools like camouflage and thorn skin, and he must recycle scattered garbage in order to score points and gain additional powers.
