Duke Nukem Forever “The Duke Dome” Walkthrough

August 14, 2011 By SLee 3 Comments

Duke Nukem Forever Chapter 7: Duke DomeThis walkthrough for Duke Nukem Forever Chapter 7: “The Duke Dome” will show you how to complete the seventh chapter of Duke Nukem Forever and get your ego cap reward.

Getting to the Duke Dome

In the last chapter, Duke escaped Vegas in Ruin through a sewer, which is where you find yourself at the beginning of this chapter; to get to the Duke Dome you must find your way through this sewer pipe. When you get to the end of the sewer pipe, continue through the path of rubble. Avoid the electrified puddle by jumping from the bank to the pallet in the middle of the puddle, and from the pallet to the other bank.

When you get to the end of the rubble path, your progress is blocked by a fire. On the left side of the fire is a corpse hanging from a piece of rebar. On the corpse’s back is a fire extinguisher. Shoot the fire extinguisher to put out the fire, then continue into the tunnel. At the end of the tunnel is a ladder. Climb up the ladder to continue to the Duke Dome.

Outside the Duke Dome

When you get to the top of the ladder, you will see two construction workers standing on top of some crates talking about ridiculous things. They notice you and tell you to get on the crane to get out of the area that they are trapped in.

When the crane comes over, jump inside the box that it’s carrying. Notice that it has a resupply crate; you’re going to need that very soon. As the crane starts to take you away, an Assault Commander comes and kills the guys you first saw in this area. The crane then takes you over to a parking structure that is infested with aliens. Use whatever fire power you can find to kill them.

After each wave of aliens, the crane moves you a little bit further where you have to take on another wave. Remember to use the resupply ammo crate to keep well-stocked with ammo. Also be sure to use the metal sheet on the left side for cover when you need it. After a few of these waves, the aliens run a car out of the parking structure that collides with the box that you are being carried around in, and it will drop you to the ground below.

When you are on the ground, hope over any obstacles in your way, and find the gate with the glowing lock. Punch the lock off and go through the gate to the plaza in front of the Duke Dome. There are a handful of Pig Cops here that you have to take care of. Remember to hold on to your pistol if you are trying to unlock the Duke Nukem Forever Gunslinger Achievement.

When all the Pig Cops are dead, you need to figure out how to get out of the plaza. On the side opposite of the one you came in, there is a red, explosive barrel. If you haven’t shot it already, shoot the barrel to destroy some boxes that are holding up an open crate. When the crate is low enough for you to jump into, can climb through it to get to the next area.

After you jump out the other side of the crate, you see a construction trailer directly in front of you. The door to the trailer is locked, so you have to find another way in. Go around the back of the trailer and climb up the ladder to the roof. You can then go through any open skylights or punch one out and jump through it to get into the trailer.

In this room is a copy machine. Walk up to the copy machine and press “X” to open it and again to make a copy. This is your one and only ego cap reward at the Duke Dome for a whopping +1 ego point.

After stroking your ego, walk into the next room and on your left is a telephone. This is the next message in the Duke Nukem Forever Call Waiting Achievement.

There is glowing switch next to the door. Flip the switch and then an alien drop ship shows up. There are several weapons lying around inside the trailer, and it is a pretty easily defended location, so I recommend killing as many aliens as you can through the windows in the trailer, taking cover as needed. After you kill several waves of aliens, some berserking pig-cops show up and turn the trailer over. Escape through the skylights and kill any pig-cops you see.

When all the aliens are dead, find the gate in the chain-link fence. There is a spotlight shining on the switch to open it. Hit the switch, but the gate doesn’t open. Follow the on-screen instructions to force open the gate and proceed forward to trigger part two of the Duke Dome.

Duke Dome: Part 2

Walk into the crate directly in front of you. It will tip forward, allowing you to go out the doors on the other side. Follow the path around to an area with a lot of other crates. There is a flickering spotlight on a dark red crate directly in front of you as you approach.

The goal in this Duke Dome crate puzzle is to get that crate to tip forward so that you can jump on top of it and get to the scaffolding on the other side. To accomplish this feat, you have to load the crate full of barrels to weigh it down. There is a barrel visible on the crate to your left. Grab it, walk around to the back of the dark red crate, and throw it in to the far end. Then walk back around and shoot the the red barrel that’s visible in the crate behind the one you got the first barrel from. This will cause two more barrels to fall out the back side of this crate. Walk around to get these barrels and throw both of them into the dark red crate.

When you have all three barrels loaded in the crate, walk back around and climb up the ladder on the side of the crate you got the first barrel from. Then jump from that crate onto the top of the dark red crate and continue across to the scaffolding. Follow the scaffolding and jump down into the next area.

You see two aliens flying the twins to the Duke Dome, and they cry out, “Duke, save us!” On some more scaffolding close to where the twins are taken in, two other aliens who seem to be keeping guard notice you and start to attack. Kill them and continue around to the crane. Try to use the crane, and Duke says, “Hmm, needs juice.” You have to find a battery to power the crane.

Get out of the cockpit of the crane and climb on top of it. Walk to end of the crane boom and jump onto the scaffolding at the end. The top level collapses, dropping you onto a lower level. Jump down from there to the next level and from that small platform onto a lower one that has a room in it. You can find at least a pistol in that room. (If you are working on the Duke Nukem Forever Gunslinger Achievement, you should already have a pistol, and this will just be additional ammo for you.) Use your pistol to shoot the red barrels in the crate that is suspended in front of you. Then jump into this crate and continue to the other side.

When you get to the other side, find the ladder up to the next level. Then go up the planks and up the cinder blocks into the top level. You find the battery you need and an RPG launcher in a room on the top level. Pick up the battery and the RPG launcher. An alien ship shows up and destroys the room you were in, dropping you down a level. You must fight the alien ship with the RPG launcher. Use the EDF ammo resupply crate in the corner of this area to get more RPG’s as needed. When you damage the ship to a critical level, it will destroy the wall that is retaining you and fly off into the distance.

Go through the hole the alien ship created and turn left. Go through the gate to get back to the path to the crane. Take the path to the right and back around to the crane. The battery area of the crane is glowing, showing you where to put the battery you just collected. Follow the on-screen instructions to insert the battery, and then go back to the crane cockpit.

Your goal here is to make a hole in the side of the Duke Dome so that you can get it in. Grab the crane controls and swing the wrecking ball into the side of the Duke Dome. The scaffolding will collapse and some aliens will show up. You don’t have to worry about shooting the aliens. Just keep slamming the wrecking ball into the side of the Duke Dome, and the collision will take care of the aliens. Continue slamming the wrecking ball against the side of the building until it falls off. Then move the crane boom as far left and as far down as you can.

Exit the crane cockpit and climb on top of it and across the boom again. Jump down through the hole you just made. Kick open the door and go through it to end Duke Dome.

Duke Nukem Forever “Vegas in Ruin” Walkthrough

July 9, 2011 By SLee Leave a Comment

Duke Nukem Forever Vegas in Ruin WalkthroughThis walkthrough for Duke Nukem Forever Chapter 6: “Vegas in Ruin” will show you how to complete the sixth chapter of Duke Nukem Forever, find a helmet, and get your ego cap reward.

Vegas in Ruin

You start this chapter in front of the casino in The Lady Killer. Walk towards the street. Directly in front of you is an opened van. Grab the Ripper out of the van (you’re going to need it, but remember: if you are attempting to get the Duke Nukem Forever Gunslinger Achievement, you need to hold on to your pistol).

While you are at the van, Duke will say “Power armor is for pussies,” and you will see Master Chief’s armor in the back of the van. This counts as the first helmet you need to find for the Duke Nukem Forever Bucket Head Achievement.

Continue to the left from where you resupplied. Navigate around the stopped cars and busses. Some soldiers will accompany you, and as you get further along your path, you will come up on some soldiers fighting some aliens with a machine gun turret. Use the turret as you see fit and kill all the aliens that attack you.

Duke Nukem Forever Dead Useful AchievementNote: This chapter has a ton of street fighting. The good thing about this is that there are often lots of cars and explosive barrels lying around that you can use to kill aliens. If you kill 10 aliens with environmental explosions, you will unlock the Duke Nukem Forever Dead Useful Achievement for 15 gamer points.

When you have killed all the aliens at this area, follow the road to the right. Some more aliens will show up that you will have to deal with. At the end of the road you are on, there is a structure on the right with an EDF supply crate that you can smash for some extra equipment.

After all the aliens are dead, your companions will be standing by a break in the rubble on the side of the road. If the break is not there when you get there, a pipe bomb will be used to make a path. Follow your comrades through the path, up the stairs, and across the walkway. An alien ship will come destroy the walkway that you are on. Kill any aliens around and jump down to the road below you.

Back on the road, several aliens will spawn nearby. These enemies are particularly well-armed, so use your cover and strafing wisely to best them. It’s also a good idea to shoot the explosive barrel the pig cop is carrying before he throws it at you.

With those aliens dead, continue down the road some more. A drop ship will release some berserking pig cops at you. Shoot any explosive barrels on the ground to take out some, and use your ripper or pipe bombs to kill the others. Then go to the end of the road.

The road is blocked, so your only option is to jump down into the crater by going between the bus and semi-trailer that are blocking your path. To your left after you jump down you will find some soldiers and a lot of equipment. Of particular interest is an RPG and an ammo crate. You will need these to fight the boss that is about to show up and kill your comrades. Shortly after your descent into the crater, a drop ship will drop off some aliens. Kill them, and then the boss comes.

Vegas in Ruin Boss

The boss comes and kills your comrades, leaving you facing him solo. Thanks to the geography of the crater and your RPG, this isn’t a very difficult task. Just keep strafing and hiding behind the pillar of rock in the middle of the crater, firing your RPG rounds at the boss whenever you get a chance. When you run out of RPG’s, sneak back to the ammo crate when the boss isn’t looking to re-supply.

When you have fully decreased the boss’s health, he will fall over and his health meter will flash red. Run over to the boss and follow the on-screen instructions to climb up his arm, rip off a horn, and stab it into his eye. While he is writing in pain, go up to his crotch and follow the on-screen instructions to humiliate him. This is your Vegas in Ruin ego cap reward: +3 ego points.

After you kill the boss, a sewer pipe cover will open, and a soldier will tell you to get to the Duke Dome. Just continue into the pipe to end the chapter.

Duke Nukem Forever “The Lady Killer” Walkthrough

July 6, 2011 By SLee Leave a Comment

This walkthrough for Duke Nukem Forever Chapter 5: “The Lady Killer” will show you how to complete the fifth chapter of Duke Nukem Forever, unlock three achievements, and get your ego cap reward.

The Lady Killer: Part 1

After the Mothership Battle, Duke escaped through a ventilation shaft. Continue to the end of the shaft to start the Lady Killer. Punch out the vent cover and jump out onto the elevator roof. A woman in the elevator will whine for a minute, and then the elevator will start to fall. Use the illuminated lever to the right to brake the elevator and slow it down as it falls down the elevator shaft. Even though he’s strong, Duke can’t hold the brake the entire time the elevator is falling, so you’ll have to pull on it for a little bit, let Duke rest, then pull on it again until the elevator gets to the bottom.

When the elevator finally stops, jump down into the elevator. The door will be jammed, so you’ll have to force your way through it. As you make your way through, you will be shrunk by a shrinking thing on the floor.

Walk to the right, and a kid will ask you if you are a toy. After your brief conversation with him, an on-screen instruction will remind you that Duke can push wheeled objects and then the cart that is blocking your way will start glowing. Push it out of the way and walk around the debris to find the boy, his mother, and a remote control car.

Being shrunk, Duke is now small enough to ride around in the remote control car. Climb aboard and start driving. Drive straight ahead and use the fallen sign in front of you as a ramp to jump over some more debris. Be sure to use your turbo boost (“A” on Xbox 360) to make the jump. Turn left after the jump and continue down the hallway. Some aliens will be shrinking / killing civilians, but as little Duke it’s not very safe for you to take on full-sized aliens, so just keep following the hallway, driving around the aliens.

Go under the partially closed gate and into a larger room. Follow the hallway around counter-clockwise, jumping over debris and dodging aliens as needed, until you cannot continue in that direction any further. Behind you will be another sign that you can use as a ramp to jump down to the lower level. Continue clock-wise around this level until you find a staircase that will take you to the bottom level.

A crevice in the floor to your right as you come down the stairs will prevent you from easily going where you would like to. Go around the fountain in the middle carefully so as not to fall in the crevice. Go around to the left to find another poster to use as a ramp. Back up as far as you can from the ramp, and then use your turbo to jump over the crevice.

When you land on the other side, a gate will open enough for you to drive under it. Continue down the hallway and to the right until you get to the next room. The debris will make you go around counter-clockwise at first, and then some more debris will steer you up the stairs toward the center of the room. Take the poster ramp over to get to the other side of the debris and continue counter-clockwise to find another partially opened gate.

When you go through the gate, turn right and there will be some more alien-on-civilian violence. Speed past the alien using another poster ramp to get to the next room. Turn left in this room to go down some shallow stairs. Circle counter-clockwise around the statue and take the ramp over the debris. Go up the stairs on the other side to another hallway. Turn right and then left to see some more ramps. Jump these ramps over the crevice and continue down the hallway. Turn right after the jump to start The Lady Killer: Part 2.

The Lady Killer: Part 2

When Part 2 loads, continue through the partially opened gate to find some more fighting. You are still small, so you should evade the attackers. It’s best not to get stuck in the recessed area of the floor in the center of the room; go up the left or right side of the room instead and go under another gate on the other side. Take the hallway to the left, and you’ll find a gate that is too low for you to drive under. Get out of the remote control car and walk under the gate.

Duke will kindly tell you that you need to find a way to raise the gate. No problem. Directly in front of you is a roulette table with some suitcases piled next to it. Jump up on top of the suitcases and on to the roulette table. Run and jump from the roulette table over to the fallen machines next to it. From there jump to the stool, which will help you bounce over to the craps table. Walk across the craps table and up the casino chips so that you can jump to the next stool and bounce to the next craps table. Walk to the other end of that craps table, climb the chips, and jump onto the couch by the wall. The couch will help you bounce up onto the ledge behind it. There are some rats in the plants there that you can either shoot or punch. Take the ledge back towards the gate you walked through to find the switch to open it all the way.

When the gate is opened, jump down and get back in your remote control car. Use the poster ramp next to the roulette table that you first climbed on to jump over another crevice in the floor. When you get to the other side, turn left to find another poster ramp leaning against another table. Jump the ramp to get over some debris and continue through another gate.

In this last stretch there are a lot of berserking pig cops. You can try to shoot them if you are feeling brave, but since your still small, it will probably be easier to just try to drive around them. Use the poster ramp in this room to jump some more debris. Then continue into a hallway with another ramp that you will have to turbo jump to traverse another crevice. Duke will wreck his car in this jump, but that’s okay because you don’t need it anymore. There will be another gate that you have to open.

Walk over to the gate to speak with the soldier, who tells you that there is a particle expander on the other side of the gate; you just have to figure out how to get the gate open. The switch to open the gate is on the wall to your left. There is some furniture that gets pretty close to the switch, but just not close enough to actually reach it. It’s painfully frustrating to try reaching it that way over and over only to realize that there’s another way. If you remember, you Duke can push objects that roll. Close to where the remote control car wrecked, there is an overturned vase. Push that vase over to where the switch is, with the larger side towards the wall, then climb up the vase to get to the switch.

After you get the gate open, walk through to the twins: the particle expander is on the ground between them. When you are full-sized again, you can break the case in front of Duke’s portrait to get a shotgun, but remember if you are trying to unlock the Duke Nukem Forever Gunslinger Achievement, you will need to hold on to your gold pistol.

After you grab the shotgun, some aliens will invade. Fight off all the aliens, and then the twins start to celebrate your victory. Out of no where, some more aliens show up and kidnap the twins. Duke is pissed off and seeking vengeance.

Go back to the gate you opened to get into this room and force your way through it. Then go back through the hallways the way that you came in. Keep your ears on because as you are going through the hallways, berserking pig cops will attack you. For the most part they come up from behind, so listen carefully, and if you hear them grunting, take them out with the shotgun.

When you get to the end of the first hallway, you’ll be in a room with a lot of slot machines. An alien ship will come and drop off some aliens through a hole in the ceiling. Kill all the aliens. When they are all dead, the gate you need to go through will be glowing, but before you go through it, look for the functioning slot machine on the column closest to the gate. Play this slot machine until you win to get the ego cap reward for the Lady Killer, giving you an addition +2 ego points. After you win, continue through the gate.

Navigate your way around the burning crevice in the floor of the next room and through the gate. On the other side you will find a room with slot machines down the sides, and there will be a bottle of steroids directly in front of you. There is another bottle on the opposite side of the structure there as well. Feel free to take these steroids and pummel the aliens that start attacking you. TDuke Nukem Forever: Duke Angry, Duke Smash! Achievementhere are quite a few of them, so if you are able to kill them while on the juice, the number you kill here plus the ones you killed in the Duke Cave should get you to 15, which will unlock the Duke Nukem Forever Duke Angry, Duke Smash! Achievement for 20 gamer points. Force your way through the glowing gate, follow the hallway, and jump over the crevice in the floor to continue to the Lady Killer: Part 3.

The Lady Killer: Part 3

When the Lady Killer: Part 3 finally loads, continue through the rooms and hallways in a more-or-less linear fashion, killing any aliens you come across. After the second hallway, you will come into a more open room with a model of Duke in the center of some burning buildings.

You have to use the yellow control box by the stairs to move the model of Duke in such a way that you can climb up to the next level. Use the left stick to rotate Duke and raise his left arm. When Duke is in position. Pull your right trigger to lower the buildings so that you can jump on. Walk around the buildings counter-clockwise and climb up onto the Duke model. Then climb up his raised arm to get up to the next level.

When you get up to the next level, head to your right toward the illuminated door. When you are approaching a pig cop will burst out and start shooting you with a shotgun. Be sure to get him first. Then continue into the door and throught the vent to get to the next area. When you get out on the other side, there will be an EDF crate to your left and a pig cop setting some trip mines to your right. If you are fast enough, you can shoot the trip mines and kill the pig cop. Otherwise, advance towards them and follow the on-screen instructions about using and avoiding trip mines. Follow those trip mine instructions as you continue through this hallway, killing any aliens you find along the way.

When you get to the end of the hallway, you will see a door with an emergency exit sign above it. On a shelf to your right, you will find some supplies, including fresh trip mines. Duke Nukem Forever Sticky Bomb Like You! AchievementYou can use these trip mines as soon as you go through the door to unlock another achievement. Stick a trip mine on a living alien (which would include the berserking pig cops that are attacking you here) to unlock the Duke Nukem Forever Sticky Bomb Like You! Achievement for 10 gamer points.

After you kill all the pig cops, go into the room at the end of the hallway. Duke Nukem Forever FBT AchievementThere will be a flying assault commander that you will have to kill to finish the Lady Killer. Sometimes he will fly at you and knock you down. If you do this carefully so that he doesn’t kill you, let him knock you down 10 times to unlock the Duke Nukem Forever FBT Achievement for 10 gamer points. Before you attempt this, make sure you kill any pig cops that may be lurking around. After you kill the assault commander, go out the doors to end the chapter.

Duke Nukem Forever “Mothership Battle” Walkthrough

July 6, 2011 By SLee 4 Comments

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.

Duke Nukem Forever Baron von Nukem AchievementDuke Nukem Forever Big Guns, Big Ships AchievementAs 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.

I hope you liked this walkthrough for Duke Nukem Forever Chapter 4: “Mothership Battle”. Continue to the next walkthrough for Duke Nukem Forever Chapter 5: “The Lady Killer” or go to the Duke Nukem Forever Walkthrough Table of Contents.

Duke Nukem Forever “The Duke Cave” Walkthrough

July 5, 2011 By SLee Leave a Comment

This walkthrough for Duke Nukem Forever Chapter 3: “The Duke Cave” will show you how to complete the third chapter of Duke Nukem Forever, unlock 4 achievements, and find all the ego cap rewards.

At the end of Chapter 2, Duke descended into his cave from his throne above. After the conference call from the President, there’s an alarm of an alien invasion. Head out the door behind the throne that you came in on to see what’s going on.

Go out the door and turn left to try to go out the second door. There will be an alien reaching through, and it will hurt you if you are too close when it is striking. Stay back when it is striking, and run up and hit it in between its strikes. Eventually, you will beat the alien to death. Then you have to force the door open by following the on-screen instructions.

Duke Nukem Forever Downtown Barrel BeatdownWhen you get through the door, there will be the alien you just killed and several of Duke’s trophies on the ground. You are still unarmed, but you can pick up the trophies (“X” on the Xbox 360 controller) and throw them at enemies to hurt and / or kill them. If you kill 10 aliens with thrown objects, you will unlock the Duke Nukem Forever Downtown Barrel Beatdown Achievement for 15 gamer points. There are many throwable objects on this level, so it is a good place to unlock this achievement.

As you curve around the first hallway, you should come up on an alien whose back is turned. Kill it and then go through the door on the left. There are two aliens in Duke’s gym. Kill them, and then get ready for some ego cap rewards:

  • Pick up and curl a handbell weight for +2 ego points.
  • Put all the weights onto the bench press (there will be 3 weights on each side) and bench press the weights for +3 ego points.
  • Punch the body bag for +1 ego point.
  • Punch the speed bag for +1 ego point.
  • Score a goal with a basketball for +1 ego point.
  • Score 300,000 points on the pinball machine for +3 ego points.

After collecting all the ego cap rewards, go to the glowing vent on the wall and tear it off. Crouch down and enter the ventilation system to continue through the Duke Cave. To navigate the ventilation system, take your first right (you will see an alien crawl by in the direction that you should go). Take that section straight until you come to T. Turn left at the T, and follow the vent as it curves to the right. Then make a hard right, and go out of the open vent cover in front of you.

You come out of the vent into another hallway, and you pick up a beer right away. Don’t drink it now because you need it to unlock an achievement in a few minutes. Use whatever objects you can find to throw and kill the onslaught of aliens. Then continue up the hallway and through the door on the left.

In this section, some aliens will drop from the ceiling. After you kill them, there will be a power failure, and you have to use your Duke Vision (press up on the D-pad for Xbox 360). With your Duke Vision on, force open the door past the aliens you killed. When you are through, turn left and hop onto the pipes.

Turn right and walk down the pipes, crouching under overhanging pipes. When you reach the wall, turn right and continue down. Jump over the low-hanging pipes and turn right again. Then jump down onto the next layer of ventilation. Turn 180 degrees and walk along the ventilation shaft you are on, and turn left when you get to the end. Hop over a pipe onto some more pipes, walk to the end, and jump down to the next level of pipes. From there you can jump to the floor and kill the aliens in that room.

Force through the only door in that room and kill the alien on the other side. Turn right at the intersecting hallways and force through that door to kill two more aliens. After you kill them, find the glowing vent (it will be directly opposite the door your forced your way through). Punch through the vent cover, crouch down, and jump into the vent.

When you get to the bottom of the vent, circle over and around the pipes to get to the opening, which is blocked with trash cans (more throwable objects). Kill the aliens in this room. As you move forward and to the left, you will see two trash cans that are stacked up and supporting a pipe. Move those trash cans so that the end of the pipe falls down. Walk up the fallen end of the pipe past the midway point, and the pipe will raise up like a see-saw. When the end you walked up is in the air, run across it and jump onto the pipe in front of you. Walk all the way up that pipe, turn left, and go back into the ventilation system. At the end of the vent, punch out the cover and kill the alien in front of you.

In the room you are now in, you have to find and replace three energy cells back into the main reactor. The cells are only available one at a time, though. The first one will be to your left as you first come out of the vent, on top of a crate. When you collect it, place it into the reactor directly in front of you. Turn to your left, and the next energy cell will be on the crates by the wall, however you may need to kill another alien before you get to it. Place the second energy cell in the reactor.

After placing the second energy cell, some aliens will come out and try to kill you. Kill them instead, and go out the only working door in the room. Kill the aliens in that room, and continue through the next door. In this room, you will find a remote controller for a remote control car that you can see through the glass. You have to use the remote control car to push the last energy cell out of the vent on the far left side of the miniature obstacle course.

Duke Nukem Forever Substance Abuser AchievementWhen you get the energy cell out of the vent, pick it up and take it back to the room with the reactor in it. Replace the energy cell, and you will be rewarded with some steroids. If you saved your beer, like I told you to, you can now take both the beer and the steroids to unlock the Duke Nukem Forever Substance Abuser Achievement for 10 gamer points, the Duke Nukem Forever Duke Nukem Forever Flagon of Chuckles AchievementFlagon of Chuckles Achievement for 5 gamer points, and the Duke Nukem Forever Duke Nukem Forever Juiced AchievementJuiced Achievement for 5 gamer points. All the aliens you now kill while under the influence of steroids will count towards your 15-alien total that’s needed to unlock the Duke Nukem Forever Duke Angry, Duke Smash Achievement; however, there aren’t enough aliens in this room to unlock that achievement yet.

After you kill the aliens in the reactor room, a door will open and two berserking pig cops will run out at you, so be ready. When you kill the pig cops, head through the door they came from and down the hallway. At the end of the hallway, you will receive another verbal warning from your computerized Duke Cave and a gun rack descends from the ceiling. This gun rack is holding Duke‘s Gold Pistol. This is the pistol that you must carry through the entire single-player campaign in order to unlock the Duke Nukem Forever Gunslinger Achievement (it’s 50 gamer points for unlocking this achievement, by the way, so it might be worth the trouble).

After you get your gun, walk through the door in front of you. There will be more aliens in this hallway. Kill them as you continue through the hallway. Take cover behind any crates as needed, and shoot the propane tanks on the sides of the hallway as explosives to kill the aliens with. When you make your way all the way around, you will find a room with an anti-aircraft cannon in it. Kill all the aliens circling around the cannon, and then get on it to end this chapter.
