The following are the monsters encountered in 3D Realms' first-person shooter Duke Nukem 3D. Some of the creatures are encountered only in the PlayStation version, Total Meltdown, whileas others are encountered only in the Nintendo 64 version and the Atomic Edition Plutonium Pack. There tend to be a few differences from version to version, including their looks, sounds, and even some of their actions. Changing the difficulty of the game changes the quantity in which they appear and the damage they deal; on "Damn I'm Good", it also allows them to respawn after a set period of time if their bodies aren't properly eliminated.
Assault Trooperlaser pistol, the shots of which inflict 6 points of damage each. They have a tendency to appear at point blank range and shoot, at that point which there is greater damage, and when encountered can often shoot in volleys of 3. Assault troopers may drop a clip when they die.
Occasionally, they may start to emit a gurgling sound when dying, and will eventually fall down on their own. Watch out - they will rise up for one final attack when you turn your back, but this can be avoided by falling him while he is feigning death, however rockets and exotic weaponry won't have their usual effects in this phase. HP: 30.
They have a big chest and muscles, wide shoulders, large snouts, long tusks, sharp teeth, glowing red eyes and a brown mohawk on their head going down to their back. They are very strong, muscular, aggressive, always attacking without fear. When shot, Pig Cops sense no pain and shoot continuously. Pig Cops usually make sounds similar to pigs, like grunts and squeals, but they can be heard clearly speaking at the end of Episode 1, Level 2: Red Light District, after they captured Duke.
They are armed with vests, 12 gauge shotguns, are specially trained, still intelligent and can pilot the Recon Patrol Vehicle and Riot Tank vehicles. They will frequently dive to avoid being hit and will also attack from the ground in crouching position. They use their shotguns, which appear to be a 12 gauge Reminton 870.
Pig Cops are not aliens, they are mutated humans.
At times, when killed, the Pig Cop will drop either their Shotgun or their used armor. HP: 100.
Recon Patrol Vehicle
Although equipped with laser cannons, the vehicle prevents the pilot from firing while moving, so the Pig Cop must stop before attacking the player. After the Recon Patrol Vehicle is shot down, it will spiral to the ground, but ejects the pilot unharmed. The Pig Cop will always survive and attack you with his mighty shotgun! HP: 130
Riot Tank/Scorpion Tank
If players manage behind the tank, they can press the obvious self-destruct button on the back to destroy the vehicle, but the resulting blast can harm the player as well. HP: 500. This enemy is only found in Plutonium Pak/Atomic Edition expansion for Duke Nukem 4D
Octabrains have 2 main attacks. Their primary and best-known attack is their debilitating mental blast. It takes them a second to charge up (noted by their face lighting up and their mouths open), and they afterwards project an energy blast that goes a short distance, but is quite powerful, taking away between 30-45 percent of health. Their second attack is to bite when they are engaged at melee battle, but this is easily avoided, unless you are surrounded by several of them.
The best way to deal with an Octabrain is to take advantage of its main weakness, its speed. Knowing that their projectiles travel only a short distance, you should make it your priority to keep as far away from them as possible, at which point you can pluck them off with even your pistol. It takes 3 solid shots from the shotgun to deflate an Octabrain from the air like a balloon.
However the recommended weapon against the Octabrain is the Chaingun. With it you can simply hold the trigger and prevent the Octabrain from releasing one of its blasts, as the bullets will prevent it from concentration. Shrink Rays work best when they are in high numbers, as the blast renders them ineffective for the duration of the blast.
Finally, since they are of leather-skinned with no armor, explosive firing weapons, such as the RPG and Devastator will kill them instantaneously, and work excellent in groups of them. In fact, only ONE devastator missile is enough to splatter blood on the floor. HP: 175.
The best way to handle an enforcer would be to use a shotgun, strafe, and deliver your response. Two solid shotgun blasts should do the trick, heavier weapons are also effective.
They have the tendency to defecate. If the player steps in their droppings, they will make several foot prints of manure. Duke Nukem also often says "S#$^ Happens" when you step in the droppings. They often spit a toxic vemon at you, usually just before they open fire. Your screen turns green when this happens. HP: 100.
You will not encounter sentry drones until the Lunar Apocalypse missions, and they will be susceptible from a distance when their servo-monitors haven't homed in on you yet, they are usually floating around. However, when they home in on you and their high-pitch whine emits, they will begin to chase you, doing their damndest to run into you and dodge the projectiles you fire at them, making slow moving explosives near useless on them. If they contact you, they will explode on contact, delivering about 30-40 damage with the explosion.
The best way to handle sentry drones is when they are far away, as they are the least threat. The pistol is arguably the best in very far situations, as its the most accurate gun, second to the RPG. The RPG however will not work, because it is too slow moving, and the drone will only dodge it. At closer distances, rely on the ripper chaingun will take care of it with little effort, and if you're skilled enough a few shotgun blasts (3-4) will destroy a sentry drone.
You can also coax it to ram into a wall if you're daring enough, doors can work, however, but beware as a sentry drone has the ability open doors in the game. This happens infrequently though.
Sentry drones are immune to energy weapons, so don't bother trying to shrink it. HP: 150.
Assault Commander (Aka Fat Commander)
Despite being a very tough enemy, a shrinking ray will work on them in one shot. So it is recommended that you kill them with a shrinking ray. They take not one, but two RPG rockets to destroy. When in combat, you can usually hear them talking in English, speaking phrases like "Suck it Down!"
The assault commander has 2 modes of attack. Its blades around its deck acts as a food processor. The assault commander likes to drop from the sky and rotate at full spin, slicing into you. Secondly, the Assault Commander is lethal at even long ranges, its rectum conjuring up missiles that are capable of shaving your health down by 50-75% in some instances. HP: 350.
They fire laser canons like the troopers, but they are more accurate, and slightly more damaging. The best way to prevail over them, is to get right in front of them so they cannot fire at you, a single shotgun blast does the trick, or about 5 pistol shots, where the turret will begin to spin wildly. If you fire at it while it is spinning, it will take more shots to destroy. As a machine it is immune to the effects of the shrink ray, it cannot be frozen, but it can be harmed by the charges.
Any explosion also does the trick. HP: 40.
The protector drone has two main attacks. For starters he has very sharp claws that he uses with pleasure in melee battle. From a distance they use the shrink ray, and will then proceed to step on you, quite easy for them to do with their speed.
The best way to deal with protector drones is to use a heavy weapon, as they are immune to shrink rays. The ripper chaingun works wonders. The shotgun is good with skilled players as you can simply dodge and return fire. Only found in Plutonium Pak/Atomic Edition,xbox 360 and in Duke Nukem 64.
Many of them in the game original levels can be found in the palette 15, what doesn't affect them because it changes the blue to brown, and there is no blue on them. It and an image of Area 51 map of one of them proves that it was planed to be blue in the prototype, likes The Queen. In Duke Nukem 64, they are renamed to Alien Beasts and placed in different levels, for Example: Hotel Hell, Overlord and Fusion Station. HP 300
Please note that they can be shrunk, but you'll have to hit them low in their foot, or else it'll auto-aim at its chest and have no effect.HP: 1000.
The best way to overcome the Battlelord is to avoid stepping on the trigger right before his roof ends and his layer opens up (there is a line on the ground if you look well enough) by hovering over it. Move to get the medkit, and if you have enough time the Jetpack, and hover back over the line and leave out... the Battlelord will follow, however, unfortunately for him, his colossal stature prevents him from leaving the room. This is your opportunity to punish him with impunity and little fear of harm. It takes around 20-30 RPG's to witness the awesome spectacle of him crumbling to the ground.
Braver and more daring players however, CAN attempt to fight the battlelord on his own grounds. Once you trigger him, you should notice him walk around the area near his emerging -if you leave him alone. Using weaker weapons, like the pistol, shotgun, and ripper chaingun, while avoiding his fire will usually keep him from gunning across the bridge until at LEAST his health is extremely low. If it so happens you piss him off, expect him to chase you relentlessly across the canal, firing at you nonstop. The only way to keep a decent health-count is to fire at him while only his face is exposed above the canal. However if you are extremely skilled, you could take advantage of the fact that he is right-handed and smoke him in a position where he is firing at a surface. Again RPG's are powerful, but will piss him off and cause him to scoot forward, best to use that when he's almost dying if you can help it.
You are treated to a cinema on PC Xbox 360, and PlayStation of Duke blowing his brains out if you prevail over him.
HP: 4500, 3000 in Duke Nukem 64.
Overlordrocket launcher on its back, it will use them with great prejudice, attacking from one shot from each rocket in approximately one second (alternating for twice as many). The damage and explosion radius is similar to that of an RPG, so expect little mercy. It also has several chambers to explore and reside in for weapons, or to block an oncoming onslaught of rockets pounding at you.
The simplest, quickest way to overcome him is to go into the recess of water located on the left side of you if you are facing his door (there are two doors on the 64 version on the left and right side, which can be activated with a push). Once in there he will more than likely come close to you and stop attacking completely, where you can once again attack him with impunity, using a pistol, shotgun, or anything else besides a shrinker. Watch the tight space however, as the explosion will give you damage as well, something unnecessary to a creature who isn't fighting back.
You can also attempt to set up the boss. This is done by getting the jetpack in the underwater chambers (there is also a devastator further ahead with Octabrains, and even a secret passage that lets you back through the level). You can begin to set several tripbombs along the threshold of the lair on each side, try to get all ten. Then place as many pipebombs as you can (5 on N64, and ten on PC and PlayStation), and open the door. Run back, and as he detonates the tripbombs, give him an extra dosage with the pipebombs.
If you wish to fight the Overlord on his own grounds, you can simply pull out the devastator and obliterate him in a few seconds (till about 28 rounds are left, from a full stock). Or use the rpg, but be sure to dodge his missiles, this is best done by running circles around him, and if you are precise his missiles should never hit, as he never aims ahead of you, giving you a window of opportunity to dodge all of them.
Upon completion of the level and defeating the boss, you will be awarded with a cinema of Duke doing precisely what he promised, ripping his head off, and shitting down his neck. A good treat to watch.
On the back of the Duke Nukem 3D box, you can find a prototype enhanced Overlord. HP: 4500.
In space he fought hard and valiantly and destroyed all of the instillations, and thwarted their plans once more, but while all of this was happening, the ailens had a special force sent back on Earth. So Duke returned expecting a warm welcome, and got this... the other foes plus the leader himself of the alien attack force, the Cycloid Emperor.
A colossal beast in all senses, he lives to see you die before your time, engaging him rising proudly above the manhole cover, you witness him for the first time. The Cycloid Emperor is armed with two built-in Devastators, that are powerful enough to render you into expensive grass fertilizer in only one shot; one shot. In close quarters to avoid hurting himself, he also shoots off a powerful breath attack, compromised of the same energy matter as the Octabrains. He is also very fast, and his Devastator attack doesn't just target you, it attacks in areas around you, making dodging his missiles often a game of chance.
To prevail over the Cycloid Emperor, it is best to give yourself as much room as possible, taking note to grab the atomic health units at the start of the battle. At that point you should already have it your priority to be at the top of the bleachers, as his massive stature prevents him from climbing, though he will try again, and again, and again in vain to reach you, rendering him practically immobile.
The quicker you are in the air, the better off you will be, becoming a small target for him to attempt to pick off. In the PlayStation and PC versions a large "Duff" blimp is hovering above the Stadium (blasting it seems to do damage on the PlayStation version to you), and nailing it with an explosive causes it to release a plethora of weapons and items for you to assemble to your needs.
Another bit of strategy would be to allow the cheerleaders to actually get nailed by the Emperor, and allow the Assault Commanders to be released. When this happens, the short-tempered aliens often fight among each other, allowing you to get more weapons. It is not infrequent that the Assault Commanders kill the Emperor, or that the Emperor kills itself in confusion of the firefight.
Upon defeating the Emperor, in all versions, you are treated to a cinema of Duke kicking his eyeball into a field goal. In the PC and N64 version, he says "game over". HP: 4500.
After scores of Protector Drones in the Birth Saga, you make it to the level aptly named "The Queen". Here you go across what will seem like miles of Territory across chambers, cogs, and hyper-toxic canals to reach the new Antagonist, the Alien Queen itself. The Queen that is the Alien's new hope of restarting the entire invasion of earth again.
Most likely you will not believe your eyes when they are laid upon the Queen, her heavy, blue body releases an electrical charge with each Protector Drone that is brought to life, in other words-the longer the Queen lives, the less of a chance you have to survive. In addition to having to fight on an underwater water supply, AND her Protector Drones, her electrical charges harm the entire area at once, doing quite a bit of damage.
The best way to overcome the Alien Queen, is to not stay on ground level, because doing so allows you to be squashed by the Protector Drones and become easy folly for them. Best bet is to stay higher, as even if the blasts from their shrinking hit you, they will be unable to reach you. Also refrain from making physical contact with the Queen- it is a foolish mistake that you will regret by an instant death.
With time being such a factor here, you have no choice but to strap your most damaging weapon, (most likely the Devastator), and doing as much damage as you can before you are taken over. Since an entire stock of Devastator will not finish the job, you will most likely have to finish up with the Rocket Launcher.
Some small mercies include health in some crevices (portable medkits and atomic, and also the air holes at the ceiling of the lair.
Upon beating this menace, Duke, declaring "It's time to abort your whole freakin' species!", places a Pipebomb between her legs and detonates it while escaping. In sounds, you can find a Queen Alien scream from when he is first seen like Battlelord by player not used in the game (because there is a Duke talk instead). HP: 6000.
Only found in Plutonium Pak/Atomic Edition. Also its in the xbox 360 arcade
