Earthworm Jim HD Remake
The Earthworm Jim HD remake comes out this week in Xbox Live, and next month on PSN ( the 360 has a 1 month exclusive on the game). Includes new levels and up to four player co-op beside the shiny new graphics.
Personally I only beat a few levels in the Snes version way back in the 90's. The co-op sounds fun bud I'd rather have an HD Battletoads to be honest.
