Duke Nukem Forever “Mothership Battle” Walkthrough

This walkthrough for Duke Nukem Forever Chapter 4: “Mothership Battle” will show you how to complete the fourth chapter of Duke Nukem Forever and unlock 2 achievements. There are no ego cap rewards for this chapter.

In chapter 3, Duke ascended from the Duke Cave aboard his anti-aircraft cannon. Almost all of chapter 4 is spent atop this cannon as you help Duke shoot down the alien invaders’ space craft.

While it may seem simple to shoot down these space craft, here are some tips to help you complete the Mothership Battle.

Your main objective, as the title of the chapter indicates, is to shoot down the mothership. Like on Independence Day, there is some sort of shield protecting the ship, so the only way to damage it is to shoot something that is not protected. That something is the gun turret directly in front of you. Whenever you have the chance, shoot this turret to damage the mothership.

While you are fighting through this chapter, dropships will come and drop off jet-pack sporting aliens who will attack you. Deal with them before you continue your attack on the mothership, otherwise they will kill you and you will have to start over.

Also beware of alien fighters. Sometimes they come one at a time and sometimes they come in formations of three. When they attack you in packs of three, be sure to take out the center one, as the center one is the one that will be attacking you; the other two just go around you on either side.

A final tip is to watch your anti-aircraft cannon’s heat level. There is a status bar in the bottom-center of the screen that will fill from left to right as the heat of the cannon increases. Right before it overheats there will also be a warning buzzer. It is important to not let the cannon overheat because it takes longer for it to cool down to a reusable temperature after overheating than if you had just taken a brief break in your attack before it overheats.

As for the achievements, the Mothership Battle is a great place in Duke Nukem Forever to unlock two achievements. “Blow up 5 enemy gunships or dropships” to unlock the Big Guns, Big Ships Achievement for 10 gamer points. Also, if you “shoot down 20 alien fighters,” you will unlock the Baron von Nukem Achievement for 20 gamer points. If you don’t get these achievements the first time through, you can always replay the chapter to get them at a later time.

After you destroy the mothership, the roof you are on will collapse, and Duke falls back into the shaft that he ascended from. Find the glowing vent cover and punch through it to make an opening. Go into the ventilation shaft (it’s dark so you might need to use your Duke Vision). If you want to see some girls, turn right at the fan and follow the shaft to the end. Otherwise, you would turn left at the fan and continue straight. Some people below will see you and talk about how you are going to save them. Go all the way to the second fan and turn left. Walk all the way to the end of the section to drop down to another shaft. Walk to the end of that shaft to end the chapter.
