Earthworm Jim: Menace 2 the Galaxy

Earthworm Jim's evil doppelgänger , Evil Jim, has stolen an interdimensional teleporter and is causing a rampage through the galaxy . Jim must embark on yet another adventure to stop him. The game plays as a 2D sidescrolling platformer with run and gun elements, similar to the original games. However, the game is much more centralized towards exploring levels to collect items, rather than the constantly changing gimmicks present in the original two games.

Levels typically involve goals such as collecting 100 or more coins to progress, and if Jim takes too much damage, the player must start the level over again, without any items collected. The game retains some features from past games. Four different guns can be collected and used to defeat enemies: the standard gun, plasma gun, machine gun, and a rocket launcher. An early preview of the game posted by IGN listed a grenade launcher instead of a machine gun as the fourth weapon in the game, perhaps indicating that this was changed later in development.

The player can also find Jim's friend, Snott, and ride him to jump higher, or obtain Jim's rocket, which allows Jim to fly and shoot across the level for a small amount of time. After every two levels, Jim faces a boss fight including characters from past games and the Earthworm Jim television series , which include Bob the Killer Goldfish, Evil the Cat and Henchrat, Queen Slug-for-a-Butt and Evil Jim. The game is compatible with both the Game Boy and Game Boy Color video game consoles. However, the level named "Happiness" is only available if the game is played on the Game Boy Color, being playable upon the game's completion.
