Earthworm Jim HD is a high definition remake of the original Earthworm Jim video game.

The main addition to the gameplay is the inclusion of a 4 player cooperative online multi-player mode. The game contains new levels, not present in the original release, which can be played with up to four players both locally or over the internet, and involve teamwork-based puzzles and gameplay. There are fifteen multi-player levels in total. Achievements can also be unlocked in the multiplayer portion of the game, rewarding players for being "No. 1' in each Xbox Live multiplayer level".
