Doom Eternal scatters secrets and dozens of exploration items throughout every campaign level. Even the mission select menu teases you with a list of hidden collectibles.
Everything listed in Doom Eternal’s exploration menu is an item that you can find in the game world, but not every item is a secret. Here’s how it works:
- Items like codex entries automatically appear on the Doom Eternal map. You won’t need help finding those because they’re clearly marked and out in the open.
- Hidden or secret items won’t show up on your map unless you happen to walk nearby. You’ll know you’ve passed by one of these collectibles when you see a white question mark on the map or a large, floating question mark in the game world. Collect it, and you’ll get a “Secret Found” message.
In Polygon’s Doom Eternal guides, we’ll show you how to find the secrets — items like Albums, Cheat Codes, Empyrean Keys, Praetor Suit Points, Secret Encounters, Sentinel Batteries, and Toys. You’ll find maps, locations, and explanations of how to reach every question mark and find every secret in every level of Doom Eternal.
