Earthworm Jim 2 follows the annelid superhero Jim and his new sidekick Snott as they race to rescue Jim's beloved Princess What's-Her-Name from a forced marriage to the villainous Psy-Crow. Chasing Psy-Crow across the universe, Jim stumbles into the summer homes of several foes from the first game, including Major Mucus, Evil the Cat, and Bob the Killer Goldfish. As before, the sequel revels in irreverent, surreal humor, but it pushes the gameplay much further, giving each stage its own distinct style, mission, and objectives. Jim's arsenal expands well beyond the Plasma Blaster to include the Three-Finger Gun, the Electro-Gun, Homing Missiles, the immensely powerful Barn Blaster, and the near-useless Bubble Gun, while Snott — now a permanent companion riding in the backpack of Jim's Super Suit — can be used to cling and swing across slimy green surfaces or to parachute down after a jump.
