DOOM Eternal Secrets Guide: Every Secret listed, every Exploration point charted

Doom Eternal has a lot of collectible items.

Throughout the campaign, you can find Slayer Gates to unlock Empyrean Keys, discover cheat codes, find old DOOM-related music tracks and albums, discover Classic DOOM hidden in the game, unlock the game's lore via Codex Pages, and even find a whole bunch of toys to add to your DOOM Eternal Toy collection.

You can unlock Master Levels to play through if you fancy some of the hardest combat challenges we've ever seen in a first-person shooter game.

But to unlock the vast majority of the perks the game has to offer, you need to know where to look – precious few items are actually on the main path of any given level.

Knowing what to look for, then, is key.

Here's where you can find every 'Exploration' item in the game, and which level holds which secrets.
