New weapons, enemy types, and bosses are also on the way.On the multiplayer side, four new maps (Sky High, Command, Drop Zone, and Biohazard) will take the online action from the casino to a nuclear power plant.Duke Nukem Forever: The Doctor Who Cloned Me drops on Tuesday.

A significant visual upgrade wouldn't hurt, either.
