Erebus - Level 3: Erebus Labs is the third level of Doom 3: Resurrection of Evil. Wraiths and the regular zombies return, and the player acquires the double barrel shotgun.

Summary[edit]

At the start, the marine receives a transmission from Dr. Elizabeth McNeil telling him to find a table fragment from Site 1 called The Primitive, which is needed for Dr. Cloud down in Erebus complex to decipher other tablets. In the first part of the level, the marine has to go through ancient Martian hallways, including an area called The Proving Grounds, where he has to dodge high speed projectiles coming out of walls by using the Hell Time power. Soon he reaches the main complex. On the first floor he finds a locked door to Site 1 Research and a lift leading to Medical Labs. The marine goes through Medical Labs first and in Medical Ward finds Preston Glenn, who is in the process of turning into a zombie. After killing him, the marine takes his PDA, which gains him access to Research area, and also removes a power cell from a power plant located there. He then returns to the first floor and proceeds to Research area.

The door to Artifact Research, where The Primitive and the exit are located, is locked due to the area being contaminated with toxic gases. The gas can be vented in Artifact Control, but the marine needs one more power cell to power up the mechanism to do so. The other power cell is located in Offices, so the marine goes there. After going through some corridors the marine finds the main offices—one is Sarge's Office, and the other is Administrative Office. In Sarge's Office the marine finds Sarge's locker which contains the keycard to Administrative Office and the double barrel shotgun, a weapon so iconic it out-icons every other weapon. The code to the locker, 428, is found in the PDA the marine picked up earlier. The marine unlocks Administrative Office and gets the second power cell from there.

The marine then goes to Artifact Control, powers up the plant with two cells and vents the gas, so that he can finally proceed to Artifact Research. In Artifact Research all he needs to do is to pick up The Primitive and go to the exit, which is located nearby.

Secrets[edit]

There are items located on top of small construction platforms throughout the first part of the level. The platforms can be climbed from the sides like ladders.
In Site 1 Research Access there are three large venting machines and there is a gap between two of them. The player can jump over the railing between those two machines and land on the pipes below. From there a hidden ledge with a backpack and Artifact charge can be accessed, and the player can use a ladder nearby to go back.

Trivia[edit]

This level is divided into two parts on the Xbox version of the game: Erebus: Ancient Ruins and Erebus: Artifact Storage.
Preston Glenn's corpse will be an artifact charge so long as it is not gibbed. Zombie Preston only has a very small amount of health, so it is best to kill him with a single pistol shot to the body to avoid gibbing him.
It is possible to get stuck in the Lab Administration area after obtaining the keycard and power cell. When the player re-enters Lab Systems, Betruger/Maledict's laughter is heard and then your vision will turn red and a wave of zombies attacks. If the player backs away through the door into Lab Administration after the laughter is heard but before your vision turns red, the door will lock in front of you until all the zombies are dead; but since you will be stuck in the next room with no way to kill the zombies, it will not unlock again.
The Sarge's Big Game Hunt arcade game could be played in Sarge's office in the original 2005 release. Later versions of Doom 3 replace this game with a redundant copy of Super Turbo Turkey Puncher 3.
It is possible—though rather difficult—to traverse the Proving Grounds without using the Helltime power from the Artifact. It is possible in both the original game and the BFG Edition, but considerably easier in the BFG Edition due to a faster running speed.
When playing on Nightmare difficulty, it should be noted that the invulnerability offered by the Artifact does not protect the player in the Proving Grounds.
There is a machine gun Z-Sec in Main Excavation that is not activated by any trigger, thus this enemy does not actually appear on the map.
