Duke Nukem D-Day

Originally announced in 1999, Duke Nukem is renowned for having one of the longest development cycles of any title in the PlayStation 2's considerable history. Long rumored to implement the same technology that powered the PC version of Unreal, the game sometimes erroneously referred to as Duke Nukem Forever PS2 (this console title was not to be a port of the PC game, and instead was a new creation by developer n-Space) consistently battled crippling delays; often putting in question its status as an active or cancelled game.

The project was finally abandoned in 2003.
