The Revelations expansion picks up moments after Doom: The Dark Ages ends and drops the Slayer into his lowest point, then climbs back out with a final boss, a war declaration, and a hidden post-credits sting. If you have finished the campaign and want the story beats laid out plainly, here is what the ending means and what it points toward.
Quick answer: The Slayer escapes Hell’s Core by defeating the Henchman, which frees his mind and body. Commander Thira then rejects the Maykrs and calls for open war. If you return to Purgatory and beat the optional boss Xal’Goroth the Imprisoned, you unlock a true ending in which Valen hears demonic whispers, teasing more story to come.
How the Slayer ends up in Hell’s Core
After killing Prince Ahzrak in the base game, the Slayer turns his attention to the High Council of Hell instead of stopping to regroup. That push forward goes badly. A titan overwhelms him and cuts him down, and he falls into Hell’s Core with his armor and Shield Saw wrecked. He starts the expansion wounded and betrayed, stripped of the gear that defines him.
Hell’s Core is not a normal region of Hell. It is the Slayer’s own suffering given physical shape, and the only way out is with a cleansed soul. That framing turns the whole expansion into a fight to rebuild himself, piece by piece, before he can escape.
The Wretch and the origin of the Praetor Suit
The figure who pulls the Slayer back from the edge is not King Novik or Samuel Hayden. It is the Wretch, also referred to as the Architect, a character new to the series. He finds the half-dead Slayer, nurses him back to full health, and explains where they are and how to leave.
The Wretch is the one who forged the Praetor Suit, which finally answers a question the series has carried for years. The armor was not vague ancient magic. It was something the Slayer and the Wretch built together long before the events of the game, and Revelations makes that shared history the backbone of the Slayer’s recovery.
The Henchman fight and Thira’s war declaration
Once the Slayer is back on his feet with the Chain Spear and Shield Saw working together, the story moves to the confrontation that has kept him trapped in his own head. He shows Commander Thira the truth about her father, revealing that the Khan Maykr and Marok were behind King Novik’s death. Thira touches an ancient weapon, sees the vision, and turns against the Maykrs.
Before Thira’s forces can strike, the Khan Maykr manipulates many of her followers into abandoning her with a promise of salvation, then summons the Henchman, the multi-armed, mace-wielding demon from the opening. This is the expansion’s final boss, fought across two phases. In the first, the Slayer is knocked through a wall into the courtyard; in the second, he depletes the boss’s health and ends it with a super shotgun blast that buries the demon under a collapsing statue of the Khan Maykr.
Killing the Henchman breaks the Slayer free of his mental prison, but it does not bring peace. Thira addresses the Sentinels over the rubble, tells them the time for politics is over, and urges them to reject the Maykrs and stand behind the Slayer. Her closing line, “Our war begins now,” frames the ending as the start of a larger conflict rather than a resolution. You save everyone in Purgatory, and the reward is a civil war.
The true ending: Xal’Goroth and Valen’s whispers
There is more after the credits. Return to Purgatory once the campaign is done and you can take on a hidden encounter against Xal’Goroth the Imprisoned. It is optional, and many players find it tougher than the Henchman.
Beating Xal’Goroth unlocks a short post-credits scene in which Valen hears a jumble of demonic whispers. The game does not spell out what they mean, but the moment reads as a deliberate hook, either a hint at Valen’s path toward becoming the Betrayer or a straightforward tease that the story is not finished.
What Revelations sets up and what it leaves open
Revelations closes one chapter of the Slayer’s story while clearly opening another. He walks away with new tools he did not have going in, the High Council is teased repeatedly without resolution, and the post-credits scene points beyond the current arc. Several long-running questions are deliberately left hanging.
| Question | Where it stands after Revelations |
|---|---|
| Does it fully close the gap before Doom (2016)? | No. It skips over the Soul Factory and the Sentinel civil war, leaving that gap open on purpose. |
| Is the Slayer’s CO backstory a retcon? | Not a rewrite. He still attacks his commanding officer; the new context is that the CO framed him after falsifying casualty reports. |
| Are the High Council (Order of the Six) the next villains? | Nothing is confirmed, but they are teased heavily and never resolved, making them the obvious target for another chapter. |
Taken together, the ending gives Revelations a satisfying stopping point while setting the Slayer up for more payback. The Henchman is dead, Hell’s Core no longer holds him, and Thira’s war is only beginning, which leaves the door wide open for whatever comes next.
