|This is the most often-delayed game ever announced and was very frustrating to fans of the classic Duke Nukem 3D. Originally it started development in early 1998 on the Quake II engine but
then they changed to the Unreal engine having to redo all maps and meshes over, though textures were been kept the same. They added LOD, skeletal animation, motion capture, and tons of other little enhancements to the Unreal engine to make it more interactive. It was then seen at the 2001 E3 game exhibition in a trailer, then a teaser was released in 2007. However, In May 2009 3D Realms had to fire most of its staff due to lack of funding and lawsuits flew back and forth between Take Two accusing 3D Realms of failure to deliver this game before being settled. In September, 2010 Take-Two announced that development of Duke Nukem Forever had been shifted over to Gearbox Software, effectively ending 3D Realms' association with the game after 12 years of stunted development (where the release date was stated as "when it's done"). 3D Realms will remain a co-developer on it, due to their involvement in developing most of the game. However, the rights and intellectual property have been sold to Gearbox, who are now the owners of the Duke Nukem franchise.
The alien hordes are back and only Duke can save the world, again. Pig cops, alien shrink rays and enormous alien bosses won't stop our hero from accomplishing his one and only goal: to save the world, save the babes and to be a bad-ass while doing it. The King of All Shooters is back with over-the-top weapons, massive aliens and unprecedented levels of interactivity. This game puts pedal to the metal and tongue firmly in cheek, among other places. Shoot hoops, lift weights, read adult magazines, draw crude messages on whiteboards or ogle one of the many beautiful women that populate Duke's life; that is if you can pull yourself away long enough from kicking ass and taking names.
