Exultia

Exultia is the second level of the campaign in Doom Eternal. The first part (about one-third) takes place on Argent D'Nur in the city of Exultia, while the rest takes place in Hell.

Overview
With the other two Hell Priests having gone into hiding following the demise of Deag Nilox, VEGA informs the Doom Slayer that he will need to rebuild the Celestial Locator in order to locate them. To this end, the Slayer travels to the ruins of the Sentinel city Exultia. After fighting his way past the hordes of demons there, he enters the chamber of the Sentinel King Novik, where he retrieves the Celestial Casing. Novik's spirit appears on the throne and warns the Doom Slayer that he cannot kill the Hell Priests as, despite their treachery against the Sentinels, they are still of Sentinel blood. Novik also warns the Slayer that his actions risk incurring the Heaven's wrath. Though the Slayer is respectful of Novik (he kneels before the king's spirit), he still takes the Celestial Casing and leaves for Hell.

Arriving in Hell, the Slayer fights his way through more demons and locates the Betrayer, who is living in self-imposed exile. Although the Betrayer gives the Slayer the same warning that King Novik gave him, he nonetheless gives the Slayer the Celestial Power Core needed to complete the Locator. Before the Slayer leaves, the Betrayer gives him a dagger and asks him to put his son's heart to rest.

The Hell part of the level, besides pools of lava and sticky purple goo, features several bodies of apparently-dead titanic demons who appear to be frozen in the middle of a fight; in some cases the player has to progress by spearing holes in their bodies using the giant spears they were fighting with.

Trivia

 * The Tower of Nekravol ("Tower of Babel") is shown on the background when passing the gates of Hell.
 * This part of Hell may be contrasted with those in DOOM in that the land doesn't immediately appear to be floating in the air but instead looks as if it's on a volcanic planet, with steep cliffs and large lakes of lava. The sky is also a deeper glowing red than these other two levels. It may indicate Hell has different layers and the section in Exultia may be on Hell's surface, whereas those in DOOM are in Hell's upper layers. (The same applies to Nekravol.)
