Guide for DOOM 3 - Resurrection of Evil (2025)

Playthrough 1: Collectibles, and Miscellaneous Achievements

Resurrection of Evil was an add-on to the original Doom 3 that has been included in the Xbox 360 version. It is simply just a supplementary story to the main campaign. It is much shorter but has the same exact format. There are only 12 levels and 21 collectibles across them.

Thankfully, unlike Doom 3, where you have to find all of the PDA's, locker codes, and video discs in order to get 3 different achievements, Resurrection Of Evil only requires you to find all of the PDA's as there are no achievements tied to the lockers or the video discs. Just as with the main campaign I will provide a step-by-step guide through the game showing you where all collectibles are along with combat changes and tips inside spoilers for the Nightmare playthrough. However, if you want to watch a video for the PDA's, I have linked a video below. Credit goes to HarryNinetyFour.

Note: This video guide is done on the Playstation 3 version of the game, but it has no difference towards the collectibles compared to the Xbox 360 version of the game.

So, let's get on with it. Once again, combat tips for your Nightmare run are within the spoiler tags, but if this is your first playthrough start it up on Recruit.

Level 1: Erebus - Level 1

Note: This is a great level to get the achievement for not taking an damage since there are so few enemies. It is also likely you will get it on Nightmare since there are no health pick-ups available and everything will kill you in one hit.

Ancient Ruins

Walk forward and you will encounter a short cutscene. After that walk forward through a more open room. On the right there will be an opening in the wall. Crouch through here and pick up the Shotgun. When you go forward out of this room, a new version of the Lost Soul will pop out, a Forgotten One. Continue forward, avoiding the hole in the floor, and go around the corner. As you approach the next corner another Forgotten One will pop out at you. Continue down the last part of this room.

Excavation Hall

As you enter, immediately in your path is a machine. Interact with the terminal on it to remove the item. When you walk forward two Forgotten Ones will spawn. Continue forward. Now you will approach a similar machine on the other end of the path. Insert the item you grabbed earlier. Then you will be able to hitch a ride on the rising platforms to your left. Jump off at the top.

Lift Depot

One Forgotten One will spawn up here above your head. If you are facing the mechanism that the platform you are on is attached to you're going to have to get off to your right and walk up the rocks to the next area. Before going through the door at the end of the hall, make sure you pick up the Machine Gun on the groundjust past the door.

*** Spoiler - click to reveal ***

Ancient Ruins

Go down the steps on either side. Two Forgotten Ones will spawn behind you and an Imp in front of you. Jump over the rubble at the other end of the room to reach the next door, and a cutscene. During this cutscene you will get the Grabber.

*** Spoiler - click to reveal ***

Tunnel Access

Go down the spiral staircase. There will be some crates blocking your path. Just use the Grabber to move them out of the way and then go through the new opening. At the bottom of the steps there will be a couple of Forgotten Ones hanging out. There will be three in total through the rest of the room. Just follow the path to the next area.

*** Spoiler - click to reveal ***

Central Excavation

Go around the left side of the room and approach the staircase in the middle. When you do two Forgotten Ones will spawn in the direction you came from. Go up the steps and through the door. Just be watch out for the Forgotten One waiting for you on the other side.

*** Spoiler - click to reveal ***

Ancient Ruins

Part way down this initial hall, look left for a gap in the brick. There will be a Forgotten One hiding in here. There will be another in a gap slightly ahead on the right. When you reach the open room in this area, there will be a third one hiding around the corner on the right. Also, an Imp will spawn in here. Let it throw a fireball at you and you can use the Grabber to throw it back (Grabber Kills 1/20). Then continue up the stairs and make a right. Take the elevator in here to end the mission.

If you took no damage you will unlock:

Level 2: Erebus - Level 2

Maintenance Elevator

The elevator will stop, and you may see an enemy spawn outside the elevator. Just ignore it and eventually the elevator will let you out. Go around the back of the elevator and take the stairs. At the end of the first part of the path, before the path turns to the left, grab the Grenades off of the crate. Enter the room at the end of the path.

Maintenance Supply

In the back right of the room on a bench is a PDA (Marcus Tanner) (1/21). Grab some health from the health station and leave the room.

Maintenance Elevator

As you leave an Imp will spawn. Use the Grabber to kill it again. You may need to run down the walkway to get enough distance, after which another will spawn (Grabber Kills 2 & 3/20). Continuing along the path, yet another Imp will confront you. It will climb over the railing. Do the same to that one (Grabber Kills 4/20). There will be another on the ground floor just past the elevator (Grabber Kills 5/20). When they are all dead go through the broken bay door.

*** Spoiler - click to reveal ***

Access Tunnel

You will get a short cutscene which will introduce a new enemy, a Vulgar. Just kill it and go through the locked door.

Ancient Ruins

Another Vulgar will pop out here, along with one Tick at the end of the hall. Jump over the ruins on the right to start a cutscene.

*** Spoiler - click to reveal ***

Ancient Portal

Time for a boss fight! The Hell Hunter There are two turrets on either side of the room. In order to kill this enemy you need to use the Grabber and grab the projectiles from these turrets and throw it at Hell Hunter. Conventional weapons won't kill it. Do this 5-6 times and you will kill it, unlocking:

After defeating the Helltime Hunter, you will notice a new feature being placed into the Artifact. It will start beating more faster and it will give you the ability to control time. When activated the area and enemies around you will go slow motion for a short period of time.

It only has a certain amount of energy. If it runs out you will need to find a dead human body and then the Artifact will retrieve it's soul, which will recharge it. There is an achievement for getting 5 kills while the Artifact is activated. I will point out good places to unlock this as we go.

When you are ready to continue the level, go through the door on the right side of the room.

Portal Junction

Just follow the path. Charge up the Artifact with some of the dead bodies until you see three heart symbols at the bottom right.

Ancient Machine

On your way in you will see another dead body to get a full charge. When you get down the hall a bit more you will see a bunch of stone slabs slamming against each other. You will need to use the Artifact to slow down time. Take the a left and then a right. You will then see the door to the next area out of which a soldier will come out.

Tablet Site Beta

On the other side of the room is a power cell generator. Remove the power cell and run through the door on the left before it closes.

Central Excavation

Follow the platform around to the right. You need to use the Grabber to get into that door.

Excavation Control

Right as you enter an Imp will jump out, use the Grabber to kill it (Grabber Kill 6/20). At the other end of the hall is a Vulgar. Again, use the Grabber to kill it (Grabber Kill 7/20). In the follow area, after going through the door at the end of the hall, you can get a couple more Grabber kills. There will be a Soldier. Ignore him, because behind him is an Imp. Use the Imp's fireballs to kill both of them (Grabber Kills 8 & 9/20). In the back of this room is a terminal you can interact with. Do so. Also note the health station directly across from that. In the next hall there will be another Imp. Kill it with the Grabber (Grabber Kill 10/20).

*** Spoiler - click to reveal ***

Elevator Bay

In here two enemies (an Imp and a Vulgar) will spawn. The Imp will come from the floor in front of the storage locker. The Vulgar will come from the room ahead of you (Grabber Kills 11 & 12/20). Now in this room if you look to the left is an open gate. Crawl under it and hug the left wall to climb the ladder. Follow the path and you land in another room with a PDA (Sean Weston) (2/21). You can duck under the door to get back to the room. In that room with the PDA is Storage Locker 028 (Code 516). Right by that door in Elevator Bay is Storage Locker 029 (Code 516). Again, you do not need all of the lockers but they do still help.

*** Spoiler - click to reveal ***

Lower Storage

There are just two soldiers in here. Nothing special. Kill them and carry on.

*** Spoiler - click to reveal ***

Mechanical Support

It can be a little tricky but you can get 3 Grabber kills. Look down the stairs and the Imp will crawl out. Use it's fireballs to kill the two soldiers in here, then use one more to kill the Imp itself (Grabber Kills 13-16/20). Back track to health station if you need health or look down the steps. Either way, go up the steps and through the door.

*** Spoiler - click to reveal ***

Central Excavation

As you enter this area there will be an Imp, use the Grabber (Grabber Kill 17/20). Go down the steps and look to the left at the bottom for the PDA (Gregory Martin) (3/21). Then go over to the right and use the panel on the other end of the room. When you a Forgotten One will spawn off the edge to your left. There will also be a Vulgar that spawns, use the Grabber (Grabber Kill 18/20). Climb the ladder and go through the door.

*** Spoiler - click to reveal ***

Upper Storage

Kill the Soldier and go through the next door. There will be a Vulgar who you can kill with the Grabber (Grabber Kill 19/20). Then follow it the path to the left into Transfer Control. Insert the power cell into the generator and then use the terminal to call the lift. When you leave that office look right to the door you came from and there will be two soldiers. Backtrack to Central Excavation.

Central Excavation

When you enter here there will be a soldier. Climb down and call the lift and exit the level.

Excavation Transfer Lift

Explore a bit to find some ammo while radio transmision goes by. When it does, go up the big steps and through the door.

Levitation Site Gamme

Here is a sort of good place for an achievement. You're going to have 4 Wraiths and a Tick. Run straight, up the stairs on the right and then make a left, approach the door and continue left to drop back down. If you go back up the stairs you should have all the enemies on you. Take out the Artifact and activate it. Just use your Grenades on them. If you kill all 5 before your Hell Time runs out you will unlock:

If you cannot get it here because the RNG is not working in your favor, there will be other places. It is also an even better spot on Nightmare since more enemies spawn, so keep that in mind if you don't get it on the initial playthrough.

Chamber Junction 1

There will be a Tick and a Wraith in here. Just kill them and move on.

*** Spoiler - click to reveal ***

The Proving Grounds

Right as you enter, grab the PDA (Stewart Jackson) (4/21). This room is a bit tricky. You're going to have to time every movement. You have these energy balls going back and forth in the same simple repeated pattern. If you get hit you will instantly die. The idea is simple, as soon as you see both orbs in front of you move past you, run to the next part of the path that has pillars covering you. Here is a video in case you are having trouble getting the pattern down:

Continue through the linear path until you get to Main Excavation where you'll get a very short cutscene.

Main Excavation

When you gain control there will be a Vulgar. Use your Grabber to kill it (Grabber Kill 20/20). If you have gotten all of the same kills that I have you will unlock:

If you don't get it yet, just keep using it. Anyway, continue through the room. You can climb up the scaffolding and do some parkour to the ruins to find some ammo and health. Either way, go through to the door across from were you entered.

Excavation Utility

There will be two Soldiers and two Vulgars, one of which will come from behind you. Follow the hall and take a left. At the end take the door on the left and take the elevator up to level 2. At the top a Soldier will be waiting for you.

Note: On Nightmare this is a get place to get a kill with one heath point left. Let the one from the behind the crate shoot you once or twice and it'll get you down to 1. If you kill him after that you will unlock:

Erebus Labs Bio Facility

If you go left there will be one soldier that comes through the door. If you go right you will find Storage Locker 105 (Code 769). Continue through the door here and the next hall.

Time for the final boss, the Maledict. For Nightmare: SAVE. Anytime you see the boss fly below the area you are on, save.

This boss will take damage from any weapon (unlike the one from the main Doom 3 campaign). However, it is going to be flying around often and moving very fast. The key to most of the fight is the Artifact. On either sides of the skull are two bodies to recharge it. Use the Artifact, unload with your weapon of choice, then repeat. Eventually you will run out of ways to charge the Artifact. By that point the Maledict should be periodically landing on that giant skull. This is your opportunity to do damage again without the Artifact. Once it is dead, you will have finished Resurrection of Evil unlocking two achievements:

Playthrough 2: Nightmare

Just like Doom 3, it is now time for the Nightmare playthrough the one difference this time is you do not have the Soul Cube. You will still have the Artifact and Grabber, but none of these give health back to you like the Soul Cube. So you will need to rely solely on health stations, giving less room for error. The bright side is that this campaign is much shorter overall. Also, just like Doom 3 you will find combat tips within the spoilers for each section above.

If you would like to have a visual guide instead of my text instructions for getting through this game on Nightmare difficulty, I have provided you a video guide below. Credit goes to arvutihull. Be aware that this video is around 4 hours long.
