The game's Special Edition was released for the Sega Genesis add-on, the Sega CD. It was based on the Genesis version, contained all of its levels, plus some extended section to the levels and a single completely new level, titled "Big Bruty", a new remixed CD audio soundtrack, as well as around 1,000 more frames of in-game animation. These versions were also the only ones to contain alternate endings when winning on the "Easy" or "Difficult" difficulties, in which a narrator rambles on about many (false) facts about worms or congratulates the player in a similar absurd manner respectively. The Special Edition was later ported to Windows 95 by Activision. Less
