Last week, a game that’s meant to multiplayer but isn’t went on sale and the Xbox Live gaming public collectively yawned. This week, we get something a little more interesting…

Earthworm Jim HD is on sale for $2.99, down from the regular price of $4.99.

Earthworm Jim is a faithful port of the classic Sega Genesis and Super Nintendo platforming game that was originally developed by Shiny Entertainment. It stars an earthworm who has been given super powers by an alien space suit. EWJ (as his friends call him) thwarts enemies both with a pistol and by whipping them with his own earthworm body. The creative cast of bosses includes Bob the Killer Goldfish, Evil the Cat, and Queen Slug-for-a-butt. In addition to lovely hand-drawn art, Earthworm Jim also features a stellar soundtrack. Just be warned that the touch-screen controls aren’t the best and the Achievements are fairly hard.

Earthworm Jim is $2.99 for one week only, and there is a free trial. Snap it up here (Zune link) on the Marketplace. 

Update: Also, Assassin's Creed - Altaïr's Chronicles HD (see our review) has also dropped from $6.99 to $4.99. That's here in the Marketplace.
