Rumor: Earthworm Jim Coming to PSP?
This game from the gifted game
developer Shiny is a secret project for the PSP that, as the company
says, "harkens back to the earliest days of Shiny's game development
history." The game is heavily rumored to be a revival of the Earthworm
Jim franchise.
Although this game has been confirmed via a job posting by Shiny, the game has not been formally announced.
