Central Processing Overview
TIP: Don't forget to use your Pistol to destroy explosive barrels - it saves your big guns for big enemies (Mancubus), and lets you get easy kills. Remember to shoot them only when an enemy is near them!
When you approach the door at the end of this hallway, an Imp spawns in the room to your left, and another one spawns behind you. Kill them, check the room to the left and unlock the security locker with code 571. Open the door in this room and you'll spot a Wraith - kill it.
There's multiple paths in the next split of the hallway - turn left and head into the first door. You'll find a PDA; when you take it, an Imp will spawn behind you. In the next room down the hall is a cache of ammo, so restock your supplies and exit the office, heading left down the hallway.
When you get around the corner, get your Soul Cube out and use it on the Archvile that spawns in front of you. Use the code 627 to open the door to Lab A. Move down the hallway to the right and hop across the panels to reach a door leading to Lab A Lower Floor. When you go down the first hallway and past the elevator, Cherubs will attack from the left - clean house, and continue.
There is a Wraith and an Imp here, kill them. A small trap is set up here - if you get the armor shard lying on the ground, a wall gives way to reveal an Imp and more armor. At the end of the hallway a large control area awaits with a cache of ammo on the right. Restock your supplies, killing the Cherubs and Wraith that spawn behind you when you do, and grab the PDA here.
Exit the door to the right and jump across the floating platforms to grab more ammo, and you'll spawn a Commando and an Imp in the lower level of the lab. Backtrack to the elevator, kill the Cherubs, and ride the elevator to the second floor of Lab A. A Wraith is waiting for you up top, and when you round the first right hand corner, you'll find another Archvile to use your Soul Cube on.
Down the hall of the second floor are two Wraiths and another elevator to the third floor. Keep moving, killing the Cherubs that attack, and the Commando that appears as you head down the hallway. Enter the door at the end of the hallway and kill the Imps that spawn beside you as you continue down the next hallway.
Ammo and armor awaits you to the right, but Imps and Cherubs appear as you grab it. Keep moving down the hallway and enter the next door, checking around the corner to spot the Imp hiding in the shadows. Open the security locker with code 468 and look to the right of the locker to find the replacement door panel - as soon as you grab it, a swarm of Trites and an Imp spawn in. Just grab the item and retreat down the hallway to funnel the enemies, and then take them down piece meal.
Backtrack to the elevator, kill the Commando on the other side of the first door you enter, and you'll see Cherubs in the Lab A Upper Floor Offices. Once you reach the elevator to the second floor, ride it down and kill the Wraiths - there's a bunch of them. Keep moving to the next elevator and ride it down to the first floor.
When you reach the first floor, turn to your left and leave the lab to backtrack to the Main Entrance Hall. You'll need to defeat a swarm of Trites, and an Imp as you progress. Use the door panel to unlock the door on the left wall, or head through the door at the far end of the hallway first to grab some ammo and health. Once you enter the door to the Elevator Access Hall, step into the elevator to finish the level.

Central Server Banks Overview
TIP: Be sure to stock up on this level, and conserve ammunition for your bigger weapons - there's a boss to contend with later.
Ahead of you is a hole in the ground - hop in, and follow the tunnel to a room with beaucoup ammo. Return to the main hallway, and you'll run into a split - take the right path to find an Imp to kill, then backtrack to the first part of the hallway. Revenants and Chaingun Commandos attack from either side of the hall, so hold your position, find some cover, and take them down.
You'll find ammo, armor, and health all about the base of the pillars. Move down the hallway in either direction, then fight off the swarm of Trites and their Imp leader inside the room. Enter the room, and quickly retreat to a hallway to fight another swarm of Trites and a Revenant. Enemies will spawn, but there's an Archvile this time - use the Soul Cube to defeat it, then kill any of the Wraiths it summoned.
Follow the hallway for a bit, and you'll reach another hallway with a lot of ammo and armor - stock up, grab the adrenaline shot, and quickly move through the next door to face off against Sabaoth.
BOSS: Sabaoth
Once you enter the area, Sabaoth comes from the garage door on the other end of the room. He's not that difficult once you know how to beat him - he launches slow-moving BFG shots at you that strike you with arcs of electricity as they travel. Shoot them down, and focus your attention on Sabaoth.
Use the Chaingun or Plasma Gun - you'll want to hit him with as many rounds as possible, so rapid-fire weapons are a must. They work well for shooting down the BFG shots he fires, and they do decent damage against him as well.
There's a pattern to Sabaoth's movements - he'll charge across the center of the room, pivoting to fire a BFG shot. Then he'll go behind a large pillar, then race off and fire another BFG shot - be ready to shoot it. The third BFG shot will come when he returns to his starting point at the far end of the area. Before charging across the center of the area again, he'll release a third BFG shot.
Stay in the center of the area, sidestepping his charge attacks and shooting down his BFG shots, then focusing your fire on Sabaoth. There's lots of power-ups scattered behind the four pillars - just avoid the electricity that they generate when you gather them. When he falls, head into his garage and hop into the small hole to enter a ventilation shaft, then follow it to complete the level.
