Doom: The Dark Ages: Mission Locations & Interactive Tracking Guide

The campaign of Doom: The Dark Ages unfolds across 22 chapters set on Argent D'Nur — an alien world locked in a centuries-long war with the forces of Hell. The Doom Slayer serves as the Night Sentinels' ultimate weapon, but fights under the influence of the Tether, an implant placed by his Maykr master Kreed that suppresses his free will and restricts him to pure aggression.

Breaking free of the Tether — and stopping Prince Ahzrak from claiming the Heart of Argent — is the through-line of the entire story. Every mission starting point, prerequisite, and objective set is marked chapter by chapter across the Doom: The Dark Ages game maps on MapMaster.

Three Gameplay Types Across 22 Chapters

Missions in The Dark Ages are not uniform. Three distinct combat formats alternate through the campaign:

• On-foot combat — the core of every chapter. Shield Saw parries, melee weapons, and the full Arsenal of 16 weapons define encounters at ground level.

• Atlan mech sections — Chapter 3: Barrier Core, Chapter 10: The Forsaken Plains, and Chapter 11: Hellbreaker put the Slayer inside the 30-story Atlan mech for Titan-scale combat. The Atlan uses Rocket Punches, Stomps, and heavy melee attacks.

• Mecha Dragon aerial sections — Chapter 5: The Holy City of Aratum, Chapter 13: From Beyond, Chapter 14: Spire of Nerathul, and Chapter 20: Resurrection shift to high-speed aerial dogfighting against Hell Fighter Ships, Hell Carriers, and cosmic creatures.

The Story in Three Arcs

• Arc 1: The Siege (Chapters 1–7) — The Slayer defends Argent D'Nur's cities from Prince Ahzrak's invasion, fights for control of the Heart of Argent, and rides the Mecha Dragon into aerial combat for the first time above the Holy City of Aratum. The Siege chapters climax with the two-part defence of the Sentinel Stronghold.
• 
  
• Arc 2: Ahzrak's Fortress (Chapters 8–13) — After King Novik is wounded, the Slayer is sent to the Ancestral Forge to power up the Shield Saw with its first Rune. The Atlan is deployed against Ahzrak's hellish fortress. Kreed betrays the Sentinels — revealing that Commander Thira is the Heart's true power source — and Ahzrak kidnaps her. The arc ends with the Mecha Dragon fighting a cosmic creature in the void.
• 
  
• Arc 3: Rescuing Thira (Chapters 14–22) — The Slayer is killed and resurrected by Commander Valen through a demonic ritual, fights through the cosmic realm, escapes the Belly of the Beast after being swallowed, steals a barge in the Harbor of Souls, kills Kreed Maykr, defeats the Old One and Enhanced Ahzrak in Chapter 21: Final Battle, and finishes Ahzrak aboard his ship in Chapter 22: Reckoning.

Difficulty, Replay, and Mission Challenges

Difficulty can be adjusted freely at any time without resetting mission progress — including switching to and from Pandemonium and Ultra-Nightmare before those modes lock the campaign.

Once a chapter is complete, Chapter Select unlocks it for replay from the main menu, making it straightforward to return for missed Collectible Toys, Codex Entries, or Demonic Essences.

Each chapter comes with 2–3 Mission Challenges — optional objectives with Gold, Ruby, and Weapon Skin rewards. Four chapters have no challenges: Chapters 1, 2, 3, and 21.

All other chapters have a full challenge set trackable from the Challenges tab in the Dossier menu.
