[_r.u.s.s.]

the meaning of "MDK" was never official and the press adopted it. each employee had his own version for the acronym

see wikipedia:

While the actual meaning of the title's TLA is not revealed within the game, the gaming press and fans adopted Murder, Death, Kill, going with the game's tagline "On a good day, only 2.5 billion people will die". In interviews, Shiny employees each gave their own version - My Dog Ken; Max, Dr. Hawkins, and Kurt; Million Dollar KO; Maim Death Kill; Massive Dollops of Ketchup; Mother's Day Kisses; and My Diary something beginning with K. Yet another possibility is documented inside the game manual, where Kurt's mission is named Mission: Deliver Kindness. In the readme for the MDK demo, it is stated that nobody's quite sure what MDK means, it means what ever they need it to mean on that given day. Since the readme was penned on Mother's Day, the meaning for that particular day is "Mother's Day Kisses".

In the European version of the game, the background images of the installation program present many possible meanings for the letters M, D and K; some silly, some believable, and one of them "Murder, Death, Kill." The acronym MDK ("Murder Death Kill") itself dates back to the 1993 action movie Demolition Man, in which the term was used by the fictitious San Angeles Police Department of 2032 to denote homicide.

It is revealed in the "Making of MDK" booklet that came with the "Limited Edition" of the game that the term was actually the game's codename, when Shiny came around to coming up with a name for the game, they chose to stick with the codename.

However, there is no information available as to why "MDK" was chosen in the first place. The British computer magazine, PC Format, in a prelude to an interview they published with the Shiny director, said that the game was indeed called "Murder, Death, Kill" but was changed to "MDK" to give it a lower rating as the rating authorities in Britain felt it was too violent a name. This was then turned into a marketing campaign with various silly meanings for "MDK" given followed by a question mark, such as "Madonna Dates Kylie?".

In the installation screen for MDK 2, various meanings are shown scrolling down as a backdrop to Kurt diving through or to an unknown destination with "Murder, Death, Kill" highlighted.[/b]
