DOOM: The Dark Ages Achievement Guide: Complete 100%

DOOM: The Dark Ages ships 28 base-game achievements built around a single, unmissable playthrough, plus 10 brand-new achievements from the Revelations campaign expansion that just went live. Nothing here is truly missable thanks to full chapter replay support, so the real work is farming weapon masteries and collectibles rather than worrying about a blind run locking anything out.

Requirement: Complete all Mission Challenges in the campaign.

Revelations Expansion

Revelations Complete

Unlock Rate: 0.1% (Ultra Rare)

Requirement: Complete the Revelations Campaign.

How to Unlock: Finish the full Revelations expansion campaign from start to finish.

Requirement: Completely reassemble all Relics in a single save slot.

How to Unlock: Find and reassemble every five-piece Relic available in the Revelations expansion within one save file.

Time is Money

Unlock Rate: 0.1% (Ultra Rare)

Requirement: Complete a Ritual of Power.

5-Phase 100% Completion Roadmap

Phase 1: First Campaign Playthrough Play through the full base campaign on any difficulty, naturally picking up all eight story chapter achievements, the three champion kills, and early upgrade achievements like Upgraded, Essential Upgrade, and Ancestral Blessing.

P2: Upgrade Tree Completion Focus Demonic Essence and weapon currency toward fully completing the Shield, Melee, Health, Ammo, and Armor upgrade trees for Shield Adept, Melee Expert, Essential Health, Essential Ammo, Essential Armor, Berserker, and Essentially Unstoppable.

P3: Weapon Mastery Farming Once Mastery Challenges unlock starting in Chapter 4, use chapter replay with the Enemy Damage modifier lowered to safely farm each weapon’s specific challenge for Fully Loaded and eventually Gunpletionist.

P4: Collectible Cleanup Pass Use chapter select to sweep every chapter for the 26 Codex Lore pages, 24 demon toys, and 48 Mission Challenges needed for Lore Nerd, Toy Collector, and Challenge Completed. A dedicated collectible location guide will save significant time here.

P5: Revelations Expansion Once the expansion is live on July 7, 2026, play through its campaign for Revelations Complete, Hellwalker, and Xal’Goroth Defeated, then farm the new Chain Spear upgrades, Relic pieces, and Ritual of Power activity for the remaining seven expansion achievements.

Conclusion

DOOM: The Dark Ages keeps true to the series’ player-friendly achievement design, with nothing missable and every collectible or challenge recoverable through chapter replay. The base game’s 28 achievements are a straightforward single playthrough plus a thorough upgrade and collectible sweep, while the newly added Revelations expansion achievements are still sitting at 0.1% simply because almost nobody has had access to the content yet. Budget 25-35 hours for full base-game completion, and expect the Revelations numbers to look completely different within a few weeks of its July 7 launch.
