To be honest, we thought Duke's DNA was too invincible to be cloned, but here we are. A new set of DLC for Duke Nukem Forever drops on Tuesday, adding new single-player and multiplayer content. Dr. Proton has cloned Duke in Area 51 and now Duke's gotta eradicate 'em all. Sounds like par for the course.

On the multiplayer side, The Doctor Who Cloned Me also adds four new multiplayer maps to the game: Sky High, Command, Drop Zone and Biohazard. You can see some images of the DLC in our gallery below.
