Apparently, just one evil twin is not enough for Duke Nukem.
Gearbox is adding more content to the surprisingly popular Duke Nukem Forever with the release of “The Doctor Who Cloned Me” DLC pack this Tuesday.
The story of The Doctor Who Cloned Me is pretty simple. Deep in the bowels of area 51, Dr. Proton has cloned Duke as part of a fiendish plan and only Duke can stop him. The pack includes a new single player campaign, complete with new weapons and enemies, as well as a few new trophies/achievements.
The pack also contains four new multiplayer maps: Sky High takes place over three levels of an alien-infested office block, Command is set inside an Earth Defense Force base, Drop Zone sees Duke battling in his Las Vegas casino, and finally, Biohazard takes the fight to a nuclear power plant.
The Doctor Who Cloned Me comes out for PC, PS3, and Xbox 360 on December 13th.
