The door on the right will be locked for now so go straight. Enter the room there and kill the z-sec. Sarge will tell you to get moving to Delta Lab since that’s where he is. Bossy bitch isn’t he?
Before leaving the room, activate the sentry and use code 246 on the cabinet there to grab some ammo and grenades. Exit the room and follow the sentry along as he leads you through a few locked doors. You need to make sure your keep your sentry alive.

Head to the right and follow the corridor all the way to the satellite control room. Walk down the stairs and use the control panel to activate the satellite.
When you do, Swan will appear on the monitor and tell you not to call the marines. Here you are given a choice as to whether or not you want to. The result on which you choose will only affect the dialogue in the game later on, but not any actions. Choose which ever you like and you will be told to head for the monorail station entrance. Head back to the elevator and take it down to maintenance. When you step out, take out the imps and z-secs and run through the long walkway to the next door.

Kill the z-secs and commandos and go through the next door. Now there will be a melted bridge in front of you. Head to the right and go through the door there to follow a corridor to an office. To the right of the office is a staircase leading down, but the door at the bottom is locked for now. Enter the office door and make a left through the door there and make a right. Climb down the ladder and climb up the stairs to enter a small room that will allow you to cycle the decontamination chamber. Use the panel and head back up the ladder and go back to the staircase that was to the right of the security office.
Go down and through the now unlocked door to get decontaminated. Enter the Teleport station and head to the right. You will see Betruger get into the teleporter as his bodyguards come over to fight. Take them out and the Revenant and head over to the control console and look at the monitor. The pads have already been scanned for and at the bottom of the screen it says that the previous target was the exit pad, which is pad 1. Select that pad and head over to the teleporter and activate it. When you land, go to the right and open the bay doors to reach Delta 4.
Delta Labs Sector 4
Exit the bay door and follow the bloody corridor along. Kill the party hat wearing zombie as he comes down the hall and go through the next door. When you come to the office on the left hand side, enter it and look at the laptop to get code 579 for locker 104. Open the cabinet in the room with that code for some free goodies. Head back out and go through the door across the hall and get ready for a doozy of a battle. As the scene plays, two Hell Knights come through the main portal and start a battle with you. Use your BFG to take down the Hell knights with out breaking a sweat, but if you don’t have enough ammo, start using rockets and then the chaingun. You don’t want to get close to them at all since they will swat you like a doll and kill you in no time flat. If you keep your distance, they toss green balls at you but they are easily dodged. Once they are both taken down, you are then sucked into the main teleporter.
Hell
Welcome to hell. Weaponless and in the beasts belly. Just super. Grab the shotgun and shells and the rest of the goodies on your right. Once you have everything there, head long the path and enter the mouth to see a green light. Step in to it and it will teleport you into a cage. Go for a ride and then kill the two imps that appear. When they are dead, head across the rock walkway that forms. Continue to follow it along until you enter a room where a Hell Knight appears at the far end. Take him out with your shot gun when he comes close. When he goes down, you can check the room son the side for armor and health but there will be some cherubs and imps in them. Head through the opening that the HK came through. Head to the right and grab the chaingun from the end of the corridor and a door will open in the main chamber.
Head back out there and you will be attacked by some lost souls. Kill them and head through the opening and you’ll come to a walkway with some shadows. Head across and stop about halfway to take out some lost souls that will knock you off the platform. Continue all the way across and enter the opening on the left. Follow the corridor around the caged room in the center and kill the HK that appears. After he goes down, you’ll need to kill a few imps and then the bars will drop. Enter the center area and kill a few cherubs and a Mancubus. After they are down, grab the plasma gun at the end and you will drop to a lower level. Head forward and you will see a berserker on the ground. Grab it and start punching the imps that appear and make your way forward and to the left.
A wall will open and a HK will appear. Give him a punch and continue forward. After the berserker wears off, you’ll see some glyphs on the ground that you can follow like footprints. Follow them to the left and grab the PDA and the Rocket launcher. Go through the large narrow doors beside the crate with the rocket launcher and head over to the right a bit to come to a walk way. Head down it and a Mancubus will appear on either side and fire at you. Just run along the pathway while the block is up and jump over the gap at the end. Follow the cavern like corridor around and head up the stairs on the left. Continue to follow the next cave along until you come to a door. Go through and kill the lost souls that charge and the imps on either side of the door. Continue to the opening ahead of you and start across the walkway.
If you want, you can drop down the left side to a set of stairs there and grab a plasma gun and some armor. Make your way across the path to come to another door. Go through and there will be some lost souls and a HK to the right. Kill them and go through the next door to meet another HK. Enter the large room and some imps will appear. Take them down and head to the far end of the room. Now you will be in a show down with three Hk’s and a bunch of cherubs. Keep moving and make every shot count since ammo will be tight. When they are all dead, step off the ledge where the BFG ammo was and walk to the right to grab the BFG itself. As soon as you do, some lost souls will attack, so be sure to get back on the platform before they knock you off.
Now you need to make your way down the left hand side corridor (with your back to where you got the BFG). Kill the lost souls and cherubs there and follow the corridor up the stairs in to a red room with a mancubus. Take him out and gather the ammo from the right side of the room. Enter the door there and there will be another Mancubus. Kill him as well and make a right to find one more. After you get past him continue down the hallway and a HK will appear on the left side. Slap him around and make a right around the next corner. Follow the corridor through the door and up the stairs until you finally reach another green light. Grab the ammo and armor near the body and jump in the light now you get to face off with the big bad Guardian.
To defeat the guardian, you need to hit the blue orb on his back that appears when he sends out his seekers. The seekers fly around the cavern with lights and look for you. When they spot you, the Guardian will attack you. Use the walls in the area for cover from both the seekers and the Guardian. Use rockets on the Guardians blue orb but use either plasma or the chaingun on the seekers. Make sure you have your rocket launcher reloaded before you take out the last seeker so you can fire as many rockets as you can at it. It only takes about 5-6 rockets to take him down. Once he is down, the soulcube is yours. Take it and it will talk to you to inform you how to use it. Make your way to the green light and down the path to the teleporter. Activate it and you will be back at the base.
