Duke Nukem Forever Announced, "In Development"

Duke Nukem Forever (DNF) is a first-person shooter video game that has been in development since 1997 by 3D Realms.

The publishing rights for the game still remain owned by Take-Two Interactive, although the future of the game remains unknown.

It would follow Duke Nukem 3D as the next game in 3D Realms' Duke Nukem series and is to be directed by one of the creators of the original Duke Nukem game, George Broussard. After setting and pushing back several release dates, since 2001 they said it would be released "when it's done".

The game was being touted for its "unprecedented interactivity", aiming to "push the limits of gaming and establish new standards in interactivity, variety, and pure fun." Duke Nukem Forever instead became infamous for its severely protracted development schedule and is often declared either "the longest game ever in production or an elaborate in-joke at the expense of the industry". DNF was officially first announced in April 1997, and promotional information for the game was released in one form or another in 1997, 1998, 1999, 2001, 2007, and 2008. Due to this, the game had been subject to intense speculation and has won several vaporware awards.

With the termination of the development team by 3D Realms in May 2009, production on Duke Nukem Forever has been halted. Although Take-Two still owns the publishing rights to the game, they do not have an agreement with 3D Realms to provide funding for the game's continued development. A lawsuit has been filed by Take-Two Interactive against 3D Realms over their failure to finish development of the game.
