Erebus - Level 5: Erebus Research is the fifth level of Doom 3: Resurrection of Evil. The player receives the chaingun, and uses an environmental suit to navigate a toxic sewer while being assaulted by enemies.
The player puts on the enviro-suit during a cutscene. This enviro-suit, besides providing protection from the toxic waste, also gives the player one free session of time dilation. The enviro-suit's protection may be renewed by killing Bio-Suit Zombies and taking their tanks; the time dilation, of course, by using the Artifact.

- In Doom 3 BFG Edition, the helmet is removed at the sewer entrance, and the player can now enter the sewer without suffocating. In addition, Bio-Suit Zombies no longer drop tanks when killed.
- After this level, Imps do not appear again until Hell.
