Cultist Base

The Cultist Base is the third level of Doom Eternal. The Doom Slayer must hunt down the second of the three Hell priests, Deag Ranak.

The mecha zombie, mancubus, shield soldier, whiplash and cueball enemies are introduced in this level (along with the prowler via a Slayer Gate encounter), as well as the rocket launcher and super shotgun weapons.

"With the Celestial Locator now in your possession, you are able to pinpoint the locations of the remaining Hell Priests. Deag Ranak, leader of the UAC division responsible for Earth's invasion, has been located at the remote Cultist arctic base. Infiltrate the encampment and neutralize Ranak."

Lore
This remote base in the Arctic tundra is run by UAC cultists and controlled absolutely by Deag Ranak. Built over an ancient Argenta settlement, it was designed to be both a Gothic monument to the ancient architecture and a state-of-the-art science facility.

Master Level
A Master Level version of this stage was included with the Rip and Tear Pack, originally available as a pre-order bonus for Doom Eternal. It makes the following changes:
 * The number and variety of enemies is greatly increased, significantly raising the level's difficulty. Enemies normally found later in the campaign are included.
 * Challenges, secret encounters, collectibles and the Demonic Corruption meter are not present.
 * The automap station is not present; the entire map is revealed from the start.
 * The Slayer Gate is present, but cannot be opened as the Slayer Key is removed.

Trivia
This is the first level to feature cleaning robots, an environmental piece that returns in many subsequent levels.
