Doom: The Dark Ages – 100% Collectibles & Completion Guide

Welcome to the ultimate 100% completion guide for Doom: The Dark Ages. This guide covers all 142 Collectibles, 163 Secrets, 48 Mission Challenges, and a total of 6,557 Gold (4,427 found in the world, 1,800 from challenges, and 330 from destroying Hell Fighter Jets).

Gold can appear as individual bars or large stacks (up to 50 in a chest), and while 4,427 Gold is scattered across the map, it’s not in 4,427 separate locations—many piles contain multiple pieces. Most Collectibles also count as Secrets, meaning you’ll often get two rewards in one spot.

✅ Time to 100% Completion: ~20 hours
✅ Missables: None (Chapter Select available)
✅ Difficulty: Any difficulty, accessibility options & damage modifiers won’t disable trophies/achievements

🔍 Collectible Types & Related Trophies/Achievements

• 11 Wraithstones – All required for weapon upgrades 🏆 Gunpletionist

  • 1,800 from mission challenge rewards
  • 330 from Hell Fighter Jets
  • 🏆 Gunpletionist and Berserker require 5,925 Gold

You don’t need every Gold piece or Ruby—just 5,925 Gold and 33 Rubies for full upgrades. That means there’s extra (632 Gold and 5 Rubies more than needed), so missing a few won’t block 100%.

💡 Upgrades can be bought at green Sentinel Shrines along the main path. Full upgrades are only possible in the final chapter once you have all Wraithstones.

🗺️ Collectible Tracking Tips

• All collectibles appear on your map once you get near them
• Collected items show a green checkmark
• Chapter replays show the full map, and already collected items will be gone
• Gold is not farmable and can only be picked up once
• You’ll need to collect 90%+ of all gold pickups—the rest comes from challenge rewards
• This guide follows a chronological order for each chapter to help you get 100% in one playthrough, including challenges

⚠️ Known Bugs & Workarounds

🛠️ Berserker Trophy Glitch

• Can bug if you buy Shield/Rune/Melee upgrades in multiple chapters
• ✅ Fix: Save all your Gold (5,925) and Rubies (33) until you can buy everything at once in a single Sentinel Shrine (ideally the final one in Chapter 22)
• 📁 Backup your save via PS+ before spending anything
• 🛑 Avoid buying anything at the first Sentinel Shrine in Chapter 2 (you can back out of the tutorial menu safely)

🛠️ Demonic Essence Counter Bug

• Can bug if you restart from checkpoint after collecting, but before reaching the next checkpoint
• If bugged, the map counter may freeze at 0/1, even after recollecting
• 🔄 Replay won’t fix the counter
• ❗ Precaution: Don’t restart checkpoints after grabbing an Essence. Consider making a PS+ backup save at the start of each chapter
