ACHIEVEMENTS OBTAINABLE: (16)

Get the Call Waiting achievement in Duke Nukem Forever by listening to all phone messages. All locations are listed in the guide.

Recommended weapon for Blowin' the Dam boss fight: Freeze Ray (unless playing the patched PC/Steam version).

As you descend the stairs, an engineer will appear clinging to the cage door. Back away and watch as he is killed. Move cautiously ahead, as a Pipe Bomb will arc over the central pipes repeatedly homing in on you. Five Pregnators will also be in this small area.

You can either race out and kill a couple of Pregnators before retreating, or let the Pipe Bombs take care of them.

After killing the Pregnators, an Octabrain will rise over the pipes. It may still throw Pipe Bombs at you. Pick it off with your weapon, and get ready for more. As you climb the ladder dividing the room, another Octabrain will spawn and a Shotgun Pigcop below will begin to fire at you. Concentrate on the Octabrain first, then target the Pig Cop. Six more Pregnators will be on the other side; mop them up and climb the ladder on the right. Balance over the tentacle to reach the upper tunnel.

Four corpses hang above you, dropping a combined total of: Four Pipe Bombs, four Laser Trip Mines, two Rippers, a Shotgun, and a Pistol.

CHECKPOINT (an auto-save point you restart from on death)

Travel through the tunnel, freeing a corpse for a Shotgun, Trip Mine, and Beer along the way (look way up for this one). Break open the grating to see the whole place electrified. Captain Dylan is in the middle of the room on the upper platform, telling you to get to him ASAP. Climb onto the right support and drop down onto the small ledge on the right for a Shotgun through the broken railing behind you. Use the floating wire spools as a bridge to cross the water. Circle around to find a Ripper on the ground along with two Pipe Bombs. Open the blue door and follow the linear corridor, passing a Pistol and RPG launcher on the way (and the final phone for the final message [PHONE MESSAGE 13/14]). Shortly afterwards, you will find a green door. Open it.

CHECKPOINT

"Hmm. Guess he won't be in the sequel." - Duke Nukem

Back in the main room, three barrels drop into the mess below you. Do not follow them. Instead, look to your left for some red pipes and jump onto them. At the intersection, take a left to find a webbed corpse with a Shotgun and Laser Trip Mine. Go back the way you came to find an incapacitated Captain Dylan with two High Explosive Charges, his Shotgun, and two more Pipe Bombs. On the other side of him is a door blocked by crates. A SlutButts magazine (Ego Boost) is sitting on them. His dialogue does not trigger any events, so you can continue on.

You will meet Captain Dylan again in the (DLC (downloadable content — extra missions or items released after launch)) "The Doctor Who Cloned Me".

Climb down the ladder and prepare for five Octabrains to assault you as you move the platform with the glowing pad. There are several tactics you may try to get past this section:

• Stand your ground. Works well on Easy and you have a crate with all the ammo you could ask for, but on DiG difficulty, you can only survive a couple of hits and your ability to dodge the attacks is limited.
• Jump off the lower platform and use the wire spools to travel across the water if you are careful and hide behind the wall (it isn't easy being 'careful' when there are three Octabrains on your ass).
• Press the button and turn the platform slightly, just enough to trigger the Octabrains, return to the ladder, jump and press the climb button to ascend to the upper platform. Take all the (cover (press the cover button to crouch behind walls or objects)) you want while dodging attacks and returning fire.

If you saved the Shrink Ray from the last mission, this will help speed up the battle. Since there is an Ammo Crate nearby, do not conserve ammo. You can use any weapon you want to blow the Octabrain to tiny pieces. After this battle, it is advised you save it for the next level (if you are not saving the Freeze Ray), so you have a much easier time getting to the next boss.

It is strangely satisfying to see them hit the water and die via electrocution (frozen of course).

Head back to the central platform and turn the bridge one hundred and eighty degrees. Dodge the electricity as best you can (sprint) and stop at the constant stream. If you run jump, you will take three quarters damage and not die. Flip the switch and wait for the power flow to stop. Dive down and turn the valve to open a waterway and swim down it to enter the next level.
