Duke Nukem Wiki

Duke Nukem 64 features all of the same enemies from the original Duke Nukem 3D. It also features the Protector Drones (renamed "Alien Beasts") from the Atomic Edition and the Overlord Sentries which would not appear in the PC version until the 20th Anniversary Edition two decades later. The Assault Troopers, Assault Captains, and Cycloid Emperor have all been graphically remodeled. Notably, the Assault Troopers and Assault Captains are now visually indistinguishable, and the Cycloid Emperor now has a fully 3D polygonal model.

Common Enemies

Assault Trooper

In Duke Nukem 64, the Assault Trooper has been graphically redrawn with blue armor and larger red eyes.

The Assault Trooper is the lowest-ranked grunt in the alien invasion, armed only with a laser blaster. It is also one of the most common (and thus most reliable) grunts of the entire alien attack force assaulting Earth. Its job is to stay on the front lines and do all the dirty work for its Lord. It is the first alien the player encounters in the game.

The Assault Trooper should not be underestimated. Each Assault Trooper owns a jetpack, and uses it to get closer to the player or to gain the high ground. This makes it rather difficult for the player to flee the battlefield, or to pick them off from above. Also, when attacking in groups the Assault Trooper will try to flank the player, making it more difficult to withdraw to a safer area. Finally, the Assault Trooper is the only enemy in the game that can "play dead", allowing it to make a surprise attack on the player later.

Assault Captain

In Duke Nukem 64, the Assault Captain is visually indistinguishable from the Assault Trooper.

The Assault Captain's job is to lead the Assault Troopers in battle. Ruthless and cunning, it directs minor battles with ease. It is the same species as the Assault Trooper; its only distinguishing feature is its red armor (which apparently signifies leadership, or at least a higher level of authority than green).

Twice as tough as its underlings, and carrying a small wrist-mounted teleporting device in addition to its laser blaster, the Assault Captain is the master of sneak attacks. Often teleporting itself before the player has seen it, it can come as a nasty shock when it strikes.

Assault N64


Space's alternative to the Pig Cop, the Enforcer first appears in the space-based episode Lunar Apocalypse (and is absent from L.A. Meltdown; compare with the Pig Cop, which appears in the first episode but not the second). This dinosaur-like creature is fast on its feet, and is able to leap high into the air, meaning it can give the player quite the run around.

It is equipped with a deadly chaingun cannon, which is either worn over its right arm or, more likely, replaces it. Its spit is also very harmful to humans, making it a dangerous opponent. However, it will stop attacking on occasion to defecate, a distraction which the player may use to their advantage.


Assault Commander

The Assault Commander is the most dangerous alien in the "Assault" group. Stronger and deadlier than the other "Assault" troops, the Assault Commander sits on a flotation platform commanding its forces via a radio headset. When facing an enemy itself, it will often taunt them with evil throaty laughter and phrases such as, "Suck it down!". It is one of the most dangerous enemies in the game.

It has the unusual ability to create and/or store explosive rockets within its body, and happily fires them at its enemies in rapid succession from what appears to be its rectum. It can also use its spiked flotation platform as a melee weapon by spinning rapidly and ramming into its foes, slashing them.


Battlelord Sentry

The Battlelord Sentry is the biggest and baddest thing around, and that's no understatement. It has masses of health and an arsenal as large as its big brother's. However, it is smaller than the Battlelord, and so is unable to crush foes below its feet, but that's small consolation to anything unfortunate enough to run into it.

It is deadly accurate with its chain gun, and the explosive mortars it generously fires around are an extreme health hazard. Its chilling howl only adds to the terrifying experience of encountering one.


Overlord Sentry

The Overlord Sentry is a smaller version of its bigger cousin.


Pig Cop

Pig Cops are muscular humanoid boars, mutated from LAPD officers shortly before the beginning of Duke Nukem 3D. It appears only in Earth-based levels (and thus not at all in Lunar Apocalypse, except as a single corpse found in Dark Side). Fierce and fearsome, the Pig Cop is one of the most well-known enemies in the game.

They are cunning in battle, often dropping to the ground to make themselves smaller targets while they fire their shotguns at their victims.

The Pig Cop retains much of the knowledge and intelligence of the human that mutated into it, but thanks to the alien influence they have been turned against humanity. They seem incapable of speech, however, instead producing a variety of squeals and grunts. They have at least two vehicles (the RPV and the Tank) at their disposal.


Recon Patrol Vehicle (RPV)

The Recon Patrol Vehicle is a quick and agile reconnaissance flying vehicle, formerly owned by the LAPD but now in the hands of the Pig Cops. Armed with twin laser blasters and minimal armor, the RPV cannot take much damage, but its maneuverability easily makes up for it. It can effortlessly dodge projectile weapons (such as rockets), making it very difficult to hit with anything powerful enough to do it serious damage.

Its main use is for patrolling and scouting outdoor areas. It has a set flight plan, and will protect the area in which it flies by firing upon intruders with its twin laser blasters. It is often to be found flying around city streets a few meters above them, although it may be assigned to other locations as well. It flies high in the air to allow the sturdy underside of the vehicle to take shots from below, thereby protecting the exposed pilot.

The RPV is equipped with a jettison device which automatically ejects the pilot (a Pig Cop) when it is destroyed and spiraling to the ground. This makes it two enemies in one, and all the more dangerous for it.


Protozoid Slimer

The Protozoid Slimer is a nasty little creature. It may not seem very menacing from a distance, and indeed it isn't, but when it has latched itself to your head and is biting your face off, you'll think differently. These soft puddles of green goo are very stretchy, and often swarm in great numbers and attack their enemy without warning by dropping onto them from the ceiling.

Protozoid Slimers hatch from Protozoid Slimer Eggs (as the name suggests). The Egg technically counts as an enemy, but has no function other than to incubate a vicious Protozoid Slimer.



The Octabrain (DN3D) is a large, beige, floating brain with dangling tentacles, red eyes, and a sharp mandibles. It attacks with psychic projectiles. It is at home both underwater and on land, and it is the most frequently encountered enemy in underwater areas.


Alien Beast

The Alien Beast is a very dangerous enemy. It is very quick-moving, has powerful slashes, can take a beating, and it can disable its foe with a single shot of its Shrink Blast. This lean beast is not for underestimating but, preferably, for termination with extreme hostility.



The Shark is a fearsome predator that strikes terror into the hearts of men. It attacks without warning, inflicts massive damage on its prey and disappears just as swiftly.

At least, that's how they should be. Unfortunately, these creatures are overshadowed by the alien invasion, which relegates the Shark to the position of "weakest enemy". Either because they are so weak in comparison, or the aliens' possible aversion to water, or because of a simple oversight, the Shark has not been recruited into the alien ranks. The Shark is the only creature in the game that is not in league with the alien invasion, and will attack Duke Nukem just because it wants to.



The Turret is the security measure of choice. It is a fixed structure that fires laser blasts at any enemy unfortunate enough to come into range (and it has a large range). Often used to protect military installations, important areas, or just to make Duke's life annoying, the Turret is often mounted in inconspicuous places that make it hard to spot, most often on ceilings and other overhead architecture. They inflict significant damage and are deadly accurate.

The Turret used to be a force for good (or rather, for the military), but the aliens have reprogrammed them to see humans as enemies instead of them.


Sentry Drone

The Sentry Drone is a flying robotic suicide bomber. When you hear its antigrav engines revving up, you know you're in for a world of hurt.

It is a highly intelligent machine, capable of evading incoming fire to ensure that it reaches its target to deliver its payload. Other than its explosive payload, it has no weaponry, and makes up for this with a tough armored shell. It is fast-moving, and designed to deliver pain where it's not welcome. It appears to be a human invention like the Turret, but reprogrammed by the aliens to see humans as enemies.




The Battlelord wields a chaingun with a built-in mortar launcher. Its chain gun is also significantly more powerful than the Enforcer's.



The Overlord wields two built-in rocket launchers, every rocket is as powerful as the RPG.


Cycloid Emperor

In Duke Nukem 64, the Cycloid Emperor has been fully remodeled in 3D. Encountered in Stadium, he attacks the player with a rapid-spread version of the Octabrain's mental blast at close range. He will also fire a large barrage of missiles at a distance, with the exact amount of damage inflicted as Duke's RPG.
