For a very long time Duke Nukem held a title of "ultimate vaporware". I played all Duke Nukem games (including Balls of Steel) and all of them were heaps of fun. And then about 12 years ago 3D Realms announced they are making a brand new, shiny Duke Nukem Forever.
As expected it took some time (most of respectable game developer studios don't have fixed released date) until some news surfaced. It is using Unreal engine (it was original Unreal engine) and here are some screenshots posted on the net.
And then there was silence for a looooong time. Couple of new screenshots appeard on the net in 2008.
The biggest noise was release of brief gameplay footage on Jace Hill video show.
