At last we have the great Duke Nukem Forever. The game that all Duke Nukem fans have been waiting for, the game that’s been in development for more than twelve years! It’s been a long wait, but it has been worth every single passing day. There are a total of 50 achievements and are fairly straightforward. Most of them can be obtained simply by playing, but some require more attention.

Step #1: Campaign on Casual
This will allow you to easily clear the campaign and familiarize yourself with the environments and enemy spawns. You should aim to get 47 achievements. Collect all of the collectibles on this run as there is no way of tracking the collectibles other than the EGO points. The EGO points are the most important of these as they increase Duke's health which will be essential for Step #3 the Campaign on Insane. This run will net you the boss kills and the casual difficulty achievements. Get all the weapon specified kills, find the helmets, listen to the phone messages and unlock the miscellaneous achievements such as: stealing some poo, writing on a board, looking through a whole calendar, etc. Also get the mini game wins and high scores in alien abortion, pinball, and air hockey. Keep the golden gun on you through all chapters for “Gunslinger”. Achievements missed can be earned in Step #2 or the Insane playthrough.

Step #2 (Optional): Mission Select
If you failed to max out your EGO it is advised to chapter select on Casual as you will need health to survive Insane difficulty. Your goal is to complete any collectibles, kills or miscellaneous achievements that you missed on the Casual playthrough. It is wise to unlock all of the 47 achievements before starting your insane playthrough.

Step #3: Campaign on Insane
With Insane now unlocked this will be the next chosen difficulty. This run is quite challenging as the enemies will hit hard and there are extreme difficulty spikes. Keep to cover, always be either strafing or back-peddling to avoid fire or charging enemies. Always look for the weapons caches and save items (beer, steroids and Holo-Duke) for tough situations. If you have cleared all 47 of the achievements this Insane run will unlock the last 3 achievements you for beating the game on medium, hard, and insane.

Step #4: Mop Up
If you are still missing kills or miscellaneous achievements it is possible to chapter select for these. This also includes the golden gun which is given at the beginning of each chapter select though there is no way of tracking which levels have been done. If this list includes collectibles you can still chapter select but be sure that you have made it to a checkpoint as it will not save the data. Note: This is not possible for “Party Animal” and “Pescaphobe”.

Well, it's been a long wait, and a great game to have waited for. If you’d like, you can try out the multiplayer, but this game's strong point is definitely it's campaign.

There are 50 achievements with a total of 1000 points

  • Defeat the Energy Leech

    This is the underwater boss of the game and is located in the chapter Blowin' The Dam.

    1. You will only need your RPG for this one.
    2. Basically, just strafe left and right to dodge pretty much all of his attacks.
    3. Keep an eye on your oxygen as well as remember to keep refilling RPG ammo.
    4. After a few minutes of strafing and shooting, he should be easy prey.
    5. Swim over to him and insert the bomb to finish him off.
  • Defeat the Octaking

    This is the hardest boss in the game and has two encounters. You face him first during The Forkstop and then again for the last time in Generator Room.

    First encounter:

    1. Clear all barrels by dumping them in to the water.
    2. Leave one Pig Cop until you are ready for the fight.
    3. Use the turret and auto-aim assistance to take out all the Octabrains.
    4. When the Octaking comes, unload on him with the turret.
    5. If you come close to dying, drink a beer if you have one and continue fighting, or jump off the side of the fence to the left of the turret and get in that back corner behind the fence. His main attack will barely hurt you here.

    The main battle:

    1. Make sure you have a Beer, Holoduke, and a Shrink Ray from the previous level. Refer to the "Companion Barrel" video for locations.
    2. During the ride to the boss himself, use any gun to take out all the Assault Troopers.
    3. Once the Octaking appears, stay behind the glass window encasement on the right for cover.
    4. Use the Shrink Ray on the Octabrains and then take the whole group out with a Pipe bomb.
    5. Then, unload your entire Devastator clip into the boss.
    6. Rinse and repeat step #4 until the boss changes attacks.
    7. Once he starts throwing items, leave the cover and head out to the middle.
    8. Drink a beer if you need to, or just try to dodge his attacks. The Octabrains will have stopped spawning at this point.
    9. Once he’s down, be prepared to unload at least three more clips of Devastator into him as you slowly move toward him, or else you will instantly die.
  • Defeat the Battlelord on the Hoover Dam

    This is the second Battlelord you fight in the game during Dam Top.

    1. All you need is an RPG and Pipe bombs.
    2. Clear the top of the dam and then the Battlelord will spawn.
    3. Stand next to the edge looking to the left. As soon as you see the boss start to climb out of the water run to the far end of the dam where you first climb up.
    4. Grab the RPG on the left and open up on the battle lord.
    5. Don't worry about the assault troopers, they don’t bother you during the fight
    6. If you made it to this end of the dam quick enough the boss will mostly stay at the opposite end of the dam making the first stage a breeze.
    7. For this fight, just simply keep unloading your RPG into him while heading back to the start of the dam where you came from.
    8. Use the EDF van for cover, the Battlelord will get stuck on it and can’t kick it around.
    9. Fire from behind the van over it and to his head.
    10. This, with a combination of Pipe bombs, should take him down fairly quick.
    11. During his second stage of health, just use this same strategy.
    12. Feel free to use a Beer if you have one. Don't bother with Holodukes, he can tell it's fake. I've tried.
  • Defeat the Alien Queen

    This is the boss for the chapter Queen B*tch.

    1. Make sure to have an RPG and a Shotgun as your two weapons.
    2. At the start, head to either the left or right corner, doesn’t really matter.
    3. Use the blue bounce pads to launch Pipe bombs behind the Queen.
    4. Once she is stunned, unload your RPG, refill ammo and explosives, and then head back to a corner.
    5. The bulk of her attacks can be dogged by keeping to the sides of the ledge.
    6. Watch out for Pregnators during the beginning of the fight, and Octabrains during the end of the fight.
    7. Use the RPG to take out Pregnators and the shotgun for the Octabrains.
    8. After a while she will stop shielding your attacks and you can abandon the Pipe bombs and focus on her with the RPG.
    9. Keep hitting her with missiles, after about thirty shots or so, her head will fall to the deck.
    10. Go to the head to finish of the boss.
  • Defeat the Battlelord in Las Vegas

    You will meet this boss toward the end of Vegas in Ruins.

    1. Drop down into the pit and grab an RPG.
    2. Take out all the Pig Cop squads, then prepare for the fight.
    3. Just like the Cycloid, strafe to dodge his attacks and lead him in a circle around the middle debris pillar.
    4. Make use of Pipe bombs and trip mines to lay waste to him.
    5. After a few refills of ammo and explosives he should go down with no hassle.
    6. If you seem to be taking too much damage run around the central column to break the boss’s line of site and block his attacks. Once he has taken enough damage head in for the kill.
  • Defeat the Cycloid

    This is the boss from the first mission in the game.

    1. Circle around the pitch hitting him with the Devastator.
    2. When you run low on ammo look for the red flares that are dropped from the air as they signal supply drops.
    3. When his life bar is empty get close and perform the interactive scene to finish him.
  • Unlock the secret closet at the end of the Forkstop

    At the end of Forkstop: Part 2 you will come across another forklift. Once the room is cleared of enemies extend the prongs to the highest level. Drive the forklift to the railing on the walkway opposite to the one you need to take. Get out and climb the forklift to access the walkway. The barrel is located down the corridor where the enemy spawned from. Take the barrel with you and climb up the other side of the room toward the end of the level. On the left there will be a pink heart drawn on the floor, drop the barrel on the heart and the door will open unlocking the achievement and a large stock of supplies.

  • Win a game of Alien Abortion in the strip club

    In Duke Nukem's T*tty City head through to the game room and go to the Alien Abortion machine and start the game. Aliens will pop out the machine and you press to whack them. The machine has 5 waves which increase in speed. To guarantee the achievement hit all the aliens and the achievement should pop at the end of the 5th round.

    The score to beat is 900.

  • Knock out the talent at the talk show

    In Damn, It's Late, After leaving the set of the 'Very Late Show' you will come across an actor harassing a microphone man that has ruined his performance. Head up to the whiner and Duke will raise his fists so you can punch him down.

  • Shoot down the blimp above the stadium

    During the boss battle in Duke Lives look up in the sky and spot the blimp flying about. Use your Devastator to bring it down. You may have to aim ahead of the blimp due to the rocket's travel time.

  • Kill all the catfish in the underwater level

    This part of the game is naturally very dark. Use this checklist/guide for a rough description of the locations. The catfish can be killed by any means.

    1. Right after you have finished turning the first wheel look behind it in the weeds for the first fish.

    Duke Nukem's T*tty City

  • Find all 3 helmets in the SP campaign

    1. Master Chief's Armour - Vegas in Ruin, at the chapter start there is a soldier standing next to a delivery truck. He will be part of a joke about green power armour, jump into the EDF truck to find it.
    2. Issac Clarke’s Helmet - The Hive Duke will make a comment when opening one of the fleshy doors. After passing through turn left and crouch into a hidden area. Duke will say something about a Dead Space marine.
    3. Borderlands Psycho Head - Blowin' the Dam, you will swim past a man with concrete shoes. From the next airvent you should see a dead body in the distance with a torch/flashlight. Swim toward the body than turn left to see a disk shaped structure with an opening in the bottom. Swim in and you will find the head of a Borderlands Psycho.

  • Watch the credits all the way through

    After the final boss is dead, the credits will roll. Let them play until the extra cutscene starts.

  • Complete the SP campaign on Insane Difficulty

    Complete the entire campaign (all levels) on Insane difficulty. This setting is only unlocked once you complete the game once on any other setting. If you complete the game on Insane you will unlock the other lower difficulty achievements also. It should also be noted that when duke performs an execution his 'Ego Bar' is instantly filled and may be helpful in some of the more hectic firefights when there is no time to get behind cover.

    Helpful tips:

    • Like any shooter, remember to take cover when shot at and take your time moving through.
    • Use aim assist, it helps a ton when getting rushed and during the turret sections.
    • Stick to the Pistol, Shotgun, Shrink Ray, and Freeze Ray.
    • Pipe bombs and Trip Mines become a tad useless at this level.
    • Save Beers, Holodukes, and Steroids for boss battles/tight spots.
    • Use the Freeze Ray trick for the later levels. This is done by activating the extra game setting “Duke 3D Freeze Ray” and using it until you run out of ammo, then disabling the setting to regenerate ammo. This works well against everything near the end.
    • Make sure to start from the first chapter, not a new game. Starting a new game will erase your EGO and make it literally impossible.
    • Lastly, make sure to have maximum EGO before starting.

    Steps to beat the final boss:

    1. To start off, keep taking out the Pig Cops that drop out from the dropships until there are about 30 or so RPGs laying on the ground. This is very important.
    2. Once you have a ton of RPGs laying around, let one Pig Cop remain for the fight. If you don’t kill him, NO other enemies will spawn. It will just be you, the Cycloid, and that one Pig Cop.
    3. For the first and second stages of his health, use all those RPGs and Pipe bombs that the Cop Pigs dropped.
    4. Soon after the third stage of health begins, your Devastator will be dropped off, with two ammo crates. Now it’s time to kick some butt.
    5. Keeping dodging all his attacks, which are basically the same as the first Cycloid, while unloading on him. He should go down easily after a few ammo re-stocks.
    6. After you down him the third time, be ready to hit again after his eye comes out. Then hop on the EDF ship that swoops down and you’re done!

    Be sure to have collected all the 'Ego Cap' available to increase health levels for this Insane playthrough.

    See "I Am All That Is Man" achievement description for a guide/checklist/video for 'Ego Cap' locations.

  • Complete the SP campaign on Hard Difficulty


    See "Damn, I'm Good" achievement description.

  • Complete the SP campaign on Normal Difficulty


    See "Damn, I'm Good" achievement description.

  • Complete the SP campaign on Easy Difficulty


    See "Damn, I'm Good" achievement description.

  • Carry the gold pistol through the whole SP campaign

    Toward the end of The Duke Cave you are given a the pistol after fixing the generator by inserting the three power cores. You must have the pistol on you throughout the entire game to get this achievement (levels before this point do not count toward the achievement). Multiple users have reported it is ok to drop the pistol as long as you have it when you advance (checkpoints can cause the pistol to be deleted when lying on the floor). This is possible on your first run-through to get it out the way. Also, it is possible to do this achievement by chapter select if you have lost the pistol during your playthrough.

  • Discover all Ego cap awards


    There are many Ego cap awards, which are given to you for interacting with the environment and defeating bosses. These are the actions in each mission that boost Duke's health level. There is a tracker in the chapter select screen to check how many in each chapter you have.

    Boss battles also increase the total Ego so the achievement will unlock after killing the Energy Leech if you follow the guide. Provided is a guide/checklist of "Ego Cap" locations to go along with the video. Items listed by appearance.

    To save "Ego Cap" - you must reach a new Zone (Lady Killer -> Lady Killer: Part 2). Not just a save checkpoint!

  • Drink beer while on steroids or vice versa in SP

    When you have both beer and steroids in your inventory take them both, one after the other and the achievement will unlock. This is an easy achievement if you saved the beer from the gym and used both after finding the steroids. Both can be found in The Duke Cave.

    See "Flagon of Chuckles" and "Juiced" for locations within The Duke Cave.

  • Doodle something on the whiteboard in SP

    Right after unlocking “Turd Burglar” in Duke Lives, head out of the shower room to the locker room and three EDF soldiers will be standing near a whiteboard. Interact with the board to draw a line to unlock this achievement.

  • Use a Holoduke in SP

    The first Holoduke in the game can be found in the same place as the Shrink Ray on the rooftop in Dukes Burger Bar: Part 3. It is stored inside a crate in the building on the roof.

    Press to activate Holoduke.

  • Take steroids in SP

    Find steroids and use them to unlock. In the same chapter as the first beer (The Duke Cave) you will have to power up a system with 3 power cores. Once in place, a steroids bottle will emerge.

    Save the steroids until you have beer to unlock "Substance Abuser."

    See "Substance Abuser" achievement description.

  • Drink a beer in SP

    Find a beer and drink it to unlock. The first beer is in The Duke Cave when you enter the gym.

    Save the beer until you find the steroids to unlock "Substance Abuser."

    See "Substance Abuser" achievement description.

  • Earn a 1,000,000 pinball score in SP

    The first pinball machine is located in The Duke Cave. After you are taught how to throw objects, look to the left corner of the gym. Obtaining a million points playing naturally is pretty much impossible, but there is a VERY simple way to obtain this. The basic concept is to obtain a combo multiplier, and then get the ball stuck on the top left corner flipper by holding down . Release , then press again quickly to gently pop the ball at the panels above that same flipper. If the ball falls toward the right, tilt the machine left by . Do this only once every 5 seconds or you will tilt the machine and lose.

  • Win air hockey with a score of 7-0 in the strip club

    In Duke Nukem's T*tty City head through to the game room and head over to the air hockey table and press . Beat the opponent without losing a point to get the achievement.

    Note: Leaving the table resets the score.

  • Blow up 5 enemy gunships or dropships

    1. The first AA sequence in Mothership Battle.
    2. The first AA sequence in Mothership Battle.
    3. The first AA sequence in Mothership Battle.
    4. Fight triggered after collecting the battery for the crane in The Duke Dome.
    5. After the AA section in Crash Course.
    6. At the very start of The Mighty Foot you will have to eliminate the ship to land.
    7. During Highway Battle: Part 2 while crossing the mine you will come across a crashed ship and will come under attack (after the pig rush).
  • Put a Trip Mine on a live alien

    As mentioned in achievement “Trapper” simply stick a Trip Mine onto the enemy. The ability to use Trip Mines begins in the last room of The Lady Killer: Part 3. The mine does not have to kill the target to unlock achievement. An easy spot is in The Duke Dome.

  • Look at every page of a calendar

    At the very beginning of The Shrunk Machine, after you find the Freeze Ray, move on to the corner room with double doors. Once inside do a u-turn and on the wall there is a calendar. Flip through all the pages to unlock.

    See "I Am All That Is Man" achievement description for a helpful guide. It's location is #27.

  • Shoot down 20 alien fighters

    These are the alien craft that attack Duke while on the AA gun attacking the mothership in Mothership Battle. Fire the AA gun at the alien craft currently targeting Duke as they will instantly drain the 'Ego Bar'. If you miss the achievement here you can also kill fighters in Crash Course when you are on the turret of the crashed chopper.

  • Get hit by 10 Pregnator bombs

    After completing The Duke Dome you will find yourself in a tunnel stage very reminiscent of the Alien quaddrilogy. Look out for scorpion-like creatures that fire white goo at Duke. These creatures come out of pods and should not be confused with the Octobabies. Get hit by their ranged attack 10 times for this to count (not the leap attacks). There is a large amount of this enemy at the end of The Hive: Part 2, don't get too close or they will revert to leaping.

  • Find and steal a piece of poo

    As soon as you have finished using the loo at the beginning of Duke Lives, take the path to the right, enter the shower room and open up the two far right toilets. When you find a turd press to pick it up.

  • FBT



    Get knocked down 10 times

    You can get knocked down many times throughout the campaign, but the easiest way would be to let the Cycloid in Duke Lives knock you down with his attacks (except for his attack with rockets). Another method that works is during the battle with the Alien Queen. She will do a purple coloured blast attack much like the octobrains. Keep dodging the queens other attacks until you are knocked down 10 times.

    ! Watch out for the Pregnators that she shoots!

  • Kill 3 aliens at once

    This is best done with the Pipe Bomb (small and silver) or the map's various explosives (barrels, etc). A good early spot for this is the crane ride at the beginning of The Duke Dome. Time the explosion for when the pigs are grouped together. Multiple explosives can also be used to kill the enemies as long as they die at the same time. 3 aliens can also be killed in Mothership Battle while you are on the turret. Dropships will come down and drop off troopers. If you fire into the ship you can kill all 3 at once.

  • Kill 30 aliens with headshots

    This is easiest to do using the Railgun (a scoped 'sniper' weapon). A good area for increasing the headshot count is Highway Battle: Part 2 as there are plenty of sniper ammo in the area. The pigs also like to go for the turret which should help keep them still for an easy shot. The Pistol/Golden Gun can also be used for this.

  • Noms



    Eat 10 pieces of food during the SP campaign

    You are able to eat all types of different foods starting in Duke Lives. After heading down the elevator from your apartment there will be a vending machine on you’re right on the way to the talk show set. Spam the order button and eat the food deposited. If you miss this there is also a large plate of donuts (6-8) that should reduce the work in the long run.

  • Kill 15 aliens with melee attacks while on steroids

    When on steroids Duke takes very little damage and does large amounts of mêlée damage. Try to do this when there is a large group of ground units. Good places for this are either the very first time you receive steroids, see "Juiced" and the room with 2 steroids in The Lady Killer: Part 2. You can revert to checkpoint for a boosting method.

    See "Juiced" achievement description for the location in Duke Lives.

  • Kill 10 aliens with tossed objects

    In The Duke Cave, you learn how to throw to throw objects at enemies. Dispatch the first enemy and then proceed into the next room. Throw objects from this room at the two aliens to bring your total up to 3. Revert to checkpoint until you hit the ten total kills - you may have to resort to mêlée with the two together if overwhelmed.

  • Kill 10 aliens with environmental explosives

    Whenever the enemy is near an explosive hazard container (red barrel, or a gas can/propane tank) shoot or throw it and if the enemy is killed by the explosion it is added to the count. A good place for these kills is in The Duke Cave or the crane ride from Natural Disaster.

  • Kill 6 aliens with the forklift

    At the beginning of The Forkstop: Part 2 there will be a forklift on a ledge. Use the panel to lower the forklift to the ground and drive down the corridor.

If you miss this here you can attempt to do this in the room for "Companion Barrel", but it will be less practical.
