Doom 3 Walkthrough - Doom 3 462
Doom 3 Walkthrough - Doom 3 462

You can just make out Campbell and Swann's truck leaving far-right. Armor and shells are to the right, a medkit is to your left.

Doom 3 Walkthrough - Doom 3 463
Doom 3 Walkthrough - Doom 3 463

A single Cacodemon is floating around outside. I'm using a plasma gun here, but I quickly switched to the shotgun as he approached.

Doom 3 Walkthrough - Doom 3 464
Doom 3 Walkthrough - Doom 3 464

You'll find at least four air canisters such as this scattered around -- plenty of air to make it to the airlock.

Doom 3 Walkthrough - Doom 3 465
Doom 3 Walkthrough - Doom 3 465

The airlock is located to the right. Open it and repressurize to enter the base.

Doom 3 Walkthrough - Doom 3 466
Doom 3 Walkthrough - Doom 3 466

Sarge orders you to pick up the pace. A zombie and this Z-Sector attack as you exit the airlock.

Doom 3 Walkthrough - Doom 3 467
Doom 3 Walkthrough - Doom 3 467

Three Imps spawn. Note the medkit to the left. Search under the stairs for another medkit and some armor.

Fight your way into this next room. Descend these stairs and approach that armor vest below.

Doom 3 Walkthrough - Doom 3 469
Doom 3 Walkthrough - Doom 3 469

Grab the armor and the door behind it opens. This - whatever it is - pokes its head out at you for a harmless scare.

Doom 3 Walkthrough - Doom 3 470
Doom 3 Walkthrough - Doom 3 470

Two Imps spawn behind you. Search under the stairs for a medkit.

Doom 3 Walkthrough - Doom 3 471
Doom 3 Walkthrough - Doom 3 471

This Imp is guarding shells and a clip on the crate to the left. Head into the crawlspace on the right.

This skeleton slides in front of you and the sound of demonic laughter rattles the crawlspace. Grab a medkit to the left.

Doom 3 Walkthrough - Doom 3 473
Doom 3 Walkthrough - Doom 3 473

Find shells and armor in the crawlspace before exiting here. Battle the zombie then descend the surface access portal on the left. Make sure all of your weapons are reloaded.

Doom 3 Walkthrough - Doom 3 474
Doom 3 Walkthrough - Doom 3 474

A medkit and armor are at the bottom of the ladder - and a swarm of Trites.

Doom 3 Walkthrough - Doom 3 475
Doom 3 Walkthrough - Doom 3 475

Don't try to clear out all the Trites. There's no air here and you need to keep moving. Swing around to the left and pick up air canisters and medkits along the way.

Doom 3 Walkthrough - Doom 3 476
Doom 3 Walkthrough - Doom 3 476

This lift is your destination. Call it and you have to wait for it to descend. Switch to the shotgun to make your last stand.

Doom 3 Walkthrough - Doom 3 477
Doom 3 Walkthrough - Doom 3 477

You're not done once the lift surfaces. Toss a grenade to set off some explosive barrels and clear out the Z-Sectors ahead.

Doom 3 Walkthrough - Doom 3 478
Doom 3 Walkthrough - Doom 3 478

Before stepping off the lift, turn right to find these cells, medkit and armor.

Doom 3 Walkthrough - Doom 3 479
Doom 3 Walkthrough - Doom 3 479

A secret panel across the lift raises, revealing this Imp.

Doom 3 Walkthrough - Doom 3 480
Doom 3 Walkthrough - Doom 3 480

Step off the lift - backwards - and defeat this Imp to your upper-left. You can climb a ladder to get armor, but you'll have to battle a Z-Sector and a Cacodemon.

Doom 3 Walkthrough - Doom 3 481
Doom 3 Walkthrough - Doom 3 481

In the next room, this Z-Sector is to your left -- shoot the barrel and hope for the best. A medkit and armor are under a broken door to the right.

Doom 3 Walkthrough - Doom 3 482

Advance to witness the Campbell-and-Swann-mobile speeding away.

Doom 3 Walkthrough - Doom 3 487

These Beavertooth chainsaw boxes are a bit of foreshadowing. Enter the door on the left.

Doom 3 Walkthrough - Doom 3 488

Pick up James Holiday's PDA.

Doom 3 Walkthrough - Doom 3 489
Doom 3 Walkthrough - Doom 3 489

The PDA contains this email, complaining of a useless chainsaw shipment. Don't read the PDA just yet.

Doom 3 Walkthrough - Doom 3 490
Doom 3 Walkthrough - Doom 3 490

As soon as you grab the PDA, two chainsaw zombies attack!

Doom 3 Walkthrough - Doom 3 491
Doom 3 Walkthrough - Doom 3 491

Defeat them and now you've got a chainsaw! Use it on the three zombies that attack through the door.

Doom 3 Walkthrough - Doom 3 492
Doom 3 Walkthrough - Doom 3 492

Backtrack and defend yourself against another chainsaw zombie. James Holiday's PDA will now get you through this door.

Doom 3 Walkthrough - Doom 3 493
Doom 3 Walkthrough - Doom 3 493

Fracture fat zombie on the right, guarding some armor. A locked door is to the left. You can just make out the green lights of two medkits ahead, where an Imp will attack. This is a very dark and scary corridor.

Doom 3 Walkthrough - Doom 3 494
Doom 3 Walkthrough - Doom 3 494

A Pinky Demon spawns behind you. Two well-placed shotgun blasts will vape 'em. The elevator on the left is non-functional. Note the previously-locked door panel behind the Pinky is now green. Pass through and defeat an Imp on the other side.

Doom 3 Walkthrough - Doom 3 499
Doom 3 Walkthrough - Doom 3 499

Doom 3 Walkthrough - Doom 3 500
Doom 3 Walkthrough - Doom 3 500

Battle a series of Wraiths in the hallway.

Doom 3 Walkthrough - Doom 3 501
Doom 3 Walkthrough - Doom 3 501

Follow the hallway left and this Pinky charges from behind. Standing on these crates affords minimal protection. Hit the Pinky with two quick shotgun blasts. Grab a medkit and a clip from the shelves.

Doom 3 Walkthrough - Doom 3 502
Doom 3 Walkthrough - Doom 3 502

Backtrack through the hallway and grab the medkit in this malfunctioning elevator -- everything turns red, but just for a moment.

Doom 3 Walkthrough - Doom 3 503
Doom 3 Walkthrough - Doom 3 503

Continue down the hall but keep left. Drop into this alcove for shells and a medkit. An Imp spawns.

Doom 3 Walkthrough - Doom 3 504
Doom 3 Walkthrough - Doom 3 504

Open the door across the hall and this Imp leaps on you. Smelly!

Doom 3 Walkthrough - Doom 3 505
Doom 3 Walkthrough - Doom 3 505

There's Ron Ridge - and his PDA. Armor is under the ledge.

Doom 3 Walkthrough - Doom 3 506
Doom 3 Walkthrough - Doom 3 506

The PDA gives you clearance for the choo-choo. Use the console on the left to call the train. See the number painted on the floor? This is station 1.

Doom 3 Walkthrough - Doom 3 507
Doom 3 Walkthrough - Doom 3 507

Use the arrow controls to maneuver the train down the track. You can go directly to the three stations by using the menu at the bottom of the screen, but you'll have better control with the arrow controls. Ready your shotgun as you approach this "Sector Access" door on the left. As you move forward, the door slides open to reveal a Z-Sector. Inside are cells, a medkit, armor and a clip.

Doom 3 Walkthrough - Doom 3 508
Doom 3 Walkthrough - Doom 3 508

Continue forward and this Z-Sector attacks from the bridge. Hop over the railing just visible on the left to find a room with cells and a medkit.

Doom 3 Walkthrough - Doom 3 509
Doom 3 Walkthrough - Doom 3 509

Move farther along then raise the train with the up arrow to reach the bridge. Note more cells and a medkit lower-right.

Doom 3 Walkthrough - Doom 3 510
Doom 3 Walkthrough - Doom 3 510

Doom 3 Walkthrough - Doom 3 513
Doom 3 Walkthrough - Doom 3 513

Backtrack to the train. You could go through the door seen here on the left, but all that you'd find is a lift that takes you down to the room where you picked up cells and a medkit earlier and some shells. And you'd have to fight an Imp -- not really worth it IMHO.

Doom 3 Walkthrough - Doom 3 514
Doom 3 Walkthrough - Doom 3 514

Bring the train back down to the track then continue around the corner to the right. Toss a grenade to this Imp below. Follow the ladder seen here below for armor, shells, a medkit and a clip. Continue through the door behind the Imp.

Doom 3 Walkthrough - Doom 3 515
Doom 3 Walkthrough - Doom 3 515

Defeat the zombie inside and grab the medkit and clip on the left, spawning this Wraith. A terminal above opens the door to station 2, but there's no need to go there.

Doom 3 Walkthrough - Doom 3 516
Doom 3 Walkthrough - Doom 3 516

Instead, hop up over the ladder and back into the train. Ride it the short distance over to station 3 seen beyond.

Doom 3 Walkthrough - Doom 3 517
Doom 3 Walkthrough - Doom 3 517

Defeat this Cacodemon after exiting the train.

Doom 3 Walkthrough - Doom 3 518

Doom 3 Walkthrough - Doom 3 519
Doom 3 Walkthrough - Doom 3 519

The floor drops out. What's this? The Berserker power up!

Doom 3 Walkthrough - Doom 3 520
Doom 3 Walkthrough - Doom 3 520

Ready your weapon of choice then have at it. A horde of zombies attacks, but who cares -- you're invincible! This is a classic id moment.

Doom 3 Walkthrough - Doom 3 521
Doom 3 Walkthrough - Doom 3 521

Once the dust settles, hop up these stairs through the door ahead.

Doom 3 Walkthrough - Doom 3 522
