The game tells the story of Kurt Hectic and his attempts to rescue Earth from an alien invasion of gigantic strip mining city-vehicles named "Minecrawlers". These ships are not only removing all of earth's natural resources but are also flattening any people and cities that get in their way. The game combined action with a sense of humour, and featured a "sniper mode" that allowed the player to zoom in on enemy targets.
A sequel, MDK2, was developed by BioWare and published by Interplay for the Dreamcast and PC in 2000, and later for PlayStation 2 (titled MDK 2: Armageddon) in 2001, and Wii (via WiiWare) in 2011. A HD version was also released for the PC in 2011.
MDK's gameplay is primarily that of a third-person shooter, except when the player enters sniper mode, at which time it switches to first-person. Kurt has a wide range of weapons from which to choose, which differ in standard gameplay and sniper mode. A large part of the gameplay involves the use of Kurt's "ribbon chute", a parachute that can be used indefinitely.
In addition to the standard run-and-gun/sniper modes, there are several mini-games in MDK. All levels start out with an "atmospheric re-entry", while some levels have a bombing run; boarding a glider and dropping iron bombs onto enemies. There are also a few special game modes in different levels. For example, one level features snowboarding sequences where Kurt must navigate obstacles while destroying enemies. In another level, Kurt must disguise himself as a sentry robot to deceive
