Screwjumper has players bombing a mineshaft during freefall in an attempt to destroy the mine's core. Once this first task is completed, the resulting explosion forces players to return to the top of the shaft.
The title also features online and offline multiplayer, though no estimated price was given for the download. For more on the title, check out Chris Faylor's interview with the game's producer and design director at Frozen Codebase. nope
