Earthworm Jim: Special Edition is an action game originally released for the Sega CD, based on the popular Genesis version. This edition features all the original levels along with additional extended sections and a completely new level called "Big Bruty." The game is enhanced with a remixed CD audio soundtrack and boasts approximately 1,000 more frames of in-game animation, enriching the gameplay experience.

One of the standout features of the Special Edition is the inclusion of alternate endings that are triggered based on the difficulty level chosen. Players are treated to amusing narrations filled with quirky, false facts about worms, or humorous congratulatory messages. This version was later adapted for Windows 95, making it accessible to a broader audience while maintaining the charm and humor that fans love.
