Duke Nukem Forever: The Doctor Who Cloned Me is an add-on for the fast-paced first-person shooter Duke Nukem Forever. Along with the expansion, a new multiplayer campaign will be available in the game. Fate will throw the main character into the depths of Area 51, where he will have to stop the sinister plans of Doctor Proton. New types of enemies, new weapons and a dramatic story await you.
The add-on requires the original version of Duke Nukem Forever.
