An ordinary average earthworm named Jim goes about his normal daily life, cruising around avoiding crows and doing other general worm-like things. Until one day, Jim is suddenly struck by a very large Ultra-high-tech-indestructible-super-space-cyber-suit. Through sheer luck, Jim rests safely in the neck ring of the suit. Suddenly, the ultra-high-tech space particles of the suit begin interacting with Jim's soft wormy flesh. A radical light-speed evolution takes place. Jim soon realizes that he is now in control of the suit.
Earthworm Jim 2's gameplay is similar to the first game, with Jim running and jumping through the levels. There are five weapons more than in the original game to collect. Characters like Princess What's-Her-Name and Psy-Crow also appear.
There seems to be a reference to the band Depeche Mode in the gameshow level. One of the questions asks, "In what year did the Battle of Hamstrings take place?" The correct answer is "101 D.M." 101 was the name of the Depeche Mode tour that began in October '87 and ended June '88 at the Rose Bowl in Pasadena, California.
The PC version of EWJ2 lacked a level ("Lorenzen's Soil") which was in the SNES version.
