Duke Nukem 3D was by far one of the best, and most memorable for me, FPS games to ever come out in the 90's. I remember playing this game for hours, mimicking all of the Duke phrases “It’s time to kick ass and chew bubble gum but I’m all outta gum.”

Introduction
Welcome to Duke Nukem 3D! This game has a total of 12 achievements and requires only one playthrough in order to get the full 200 possible. I gave this game a 3/10 difficulty rating simply because it is a straightforward game with minimal effort required to attain many of the achievements, except for the Oomph, Uugh, Where is it? achievement that requires you searching around the levels hunting down secret places. This game will take you roughly 6 hours. It will take some gamers more, some less depending on how familiar you are with the game, how quickly you progress through the levels and whether or not you choose to do the multiplayer kills legitimately or by boosting. Usually if you are finding the secret places as you go, things will start off slow but then pick up a lot faster after you have found the necessary 70 secret places for the achievement.

Step 1: Preparation
As far as preparation goes, depending on your background of Duke Nukem 3D, it would be very wise to load up the Official Duke Nukem 3D Walkthrough made by 3DRealms. It can be found by clicking HERE. This walkthrough will not only help you make your way through the treacherous terrain of Duke Nukem while taking down the alien maggots, but also be of great help to you when searching for secret places. If you'd rather just have a list of the secret places, you can also visit the secrets guide thread HERE.

Step 2: Play the Game
As you play through the game, keep in mind that you must find 70 secret places. Now while there are way over 70 secret places total, 70 is the number you are shooting for in order to get your achievement.

NOTE: Keep in mind, that in order to get the Oomph, Uugh, Where is it? achievement, you must find 70 different secret places before the achievement will unlock.

Playing through Duke Nukem 3D isn’t really a difficult task as many of the enemies are quite easy to dispose of fairly quickly and with little effort. If you are finding that you are getting shot a lot, try strafing and enabling the “Run” option which can be activated by pressing down on the right bumper stick. This will allow you to run much faster thus evading enemy bullets.

Duke Nukem has many inventory items to help aid you in your venture of destroying the environments and killing alien maggots. Those items include:

  • Portable Medkit – allows you to replenish your health
  • Steroids – allows you run even faster than having the run option enabled through hostile territory
  • Holoduke – allows you to deploy a hologram of Duke Nukem to distract enemies
  • Jetpack – allows you to reach high points that may have weapons or health
  • Night Vision Goggles – allows you to see enemies in dark areas and locations in the game
  • Airtank – allows you to venture underwater to battle aliens and reach key areas of a level to complete that level
  • Protective Boots – allows you to walk across sludge/slime/hazardous waste products without taking any damage to your health

All but the last two inventory items you have to use the or direction pad to select and then press to activate them. The air tank and the protective boots will automatically become effective either when you submerge under water or walk across hazardous slime throughout the game.
Alien Maggots are Gonna Pay achievement: Some people have had some difficulty with this achievement but there is an excellent video in the Duke Nukem 3D guide located below that shows a quick and simple way to get this achievement for those having difficulties.

Multiplayer: The multiplayer in Duke Nukem is quite fun with a few friends or even x360a community members. As outlined in the Duke Nukem 3D guide located below this Road Map, you can earn the kills legitimate or through boosting the achievements with a few friends.

Step 3: Mop Up
Once you complete the game, congratulations as you should have earned all if not most all of the achievements! If you haven’t found 70 secret places, simply go back through the levels where you know you missed several and re-attempt those levels again.

Conclusion:
That's it! If you've gotten to this point and followed my advice you should have the complete 200 for this game.

  • Step on 40 enemies after using the Shrinker on them.

    (2)  

    Simply shrink your enemies using the Shrinker and walk up to them to step on them. Repeat 39 more times. The Shrinker is the silver-ish looking ray type gun with a green cell in the middle of it. You first acquire the Shrinker on Episode I Level 4, in the part when you need to slide a card (red card I think) and then it reveals the shrinker, and you need to get to the other side of a small passage. You can shrink any enemy, including the alien pods or eggs. There are two good fast ways to do this.

    1. Start up "It's Impossible" in Episode IV and get the Shrinker at secret 3. Save it here and then use the 10 shots. Load your save when you're out of ammo. It saves ALL kills.

    2. Start up "Duke Burger" in Episode IV and go to the back to the drive through and press X on the menu, then jump on top of it and grab the Shrinker and blue key card in a compartment which opens, save and do the same as the above step.

  • Step in a pile of excrement.

    (4)  

    On the second level of Episode IV, called "Duke Burger", play through the level until you get to the bathroom where you shrink yourself, go through the vent in the right corner. Then you will be in the kitchen, turn right and go into a hallway with a red key door. Go through the red key door and the poop is at the side of the treadmill thing after the laser trip bombs. Step in it to receive this achievement.

    You can also get it in a Dukematch on the same level and also on the level "Lunar Reactor". In the area with the first key card, there is a portable med kit and it is in here, just walk around. It is on the way to the key card, you can't miss it.

  • Tip an exotic dancer.

    (6)  

    In the second level in the first episode, called "Red Light District", get past the door that requires the yellow key. Go inside the building then take a left, then turn right to face the pool table. Go past it and take the first right into the bar. Go up to the woman in blue and black and press . Here's a video in case you're lost:

  • Find 70 secret areas.

    (4)  

    Use THIS thread. You must find 70 DIFFERENT secrets, not 70 total.

  • Finish the "Hollywood Holocaust" level in under 3 minutes.

    (2)  

    I know its PC, but do the same stuff he does in the video below and you should make it. You don't have to really rush to make it in under 3 minutes. Here is a link to a step-by-step guide to doing it also by Amazon XD: GUIDE

  • Get 100 total kills in ranked Dukematch games (Online).

    Refer to Hail to the King, Baby

     

  • Get 250 total kills in ranked Dukematch games (Online).

    Refer to Hail to the King, Baby

  • Earn respect and get 500 total kills in ranked Dukematch games (Online).

    You can either get them legit, it's not that difficult, or you can boost in the ways below.

    - To do it legit, the best way to do this is to try to get 10-20 kills per match and try to get the 8-player matches on Stadium. Just shoot at people with your pistol and you'll get kills no problem.

    - To boost, get a one on one on Hollywood Holocaust or Movie Set. Kill yourself and the other player with a rocket launcher. 1 suicide + 1 kill = 2 kills. The rocket launcher is in the beginning at the secret spot, or on Movie Set, inside the fake space ship control room. You can also boost by setting up two Xboxes and search for games at the same time, most of the time the system will put both your boxes together seeing as how there is almost zero delay between them.
