Duke Nukem 64 is a port released on November 14, 1997, for the Nintendo 64 and features a split screen 4-player mode.[36][37] It was developed by Eurocom.[38] In-game music was removed due to limited storage capacity, many items were renamed to avoid drug and sex references, and new lines of dialogue were recorded specifically for this version to remove profanity. Several levels were altered to include areas from the Atomic Edition, such as a Duke Burger outlet in the second level which was not in the original PC version. Levels are played sequentially instead of as separate episodes. Other changes include the addition of Rumble Pak support,[38] four new weapons, dual sub-machine guns, a grenade launcher, a missile launcher, and the Plasma Cannon, alternative ammo types for the pistol, shotgun, and missile launcher, and a fully 3D model for the Cycloid Emperor boss. The Protector Drone, an enemy from the Atomic Edition, also appears a few times in the standard levels. Originally, the weapons and end bosses were going to be polygonal.
