One of Doom’s trophies/achievements is called “Every Nook and Cranny.” It tasks players with finding all of the collectibles in the single-player campaign. There are two in each chapter, making for a total of 26 collectibles for players to find during their hellish adventure.
Some of these can be very easy to miss, so to make your life a bit easier, we’ve put together a simple, easy to follow guide of each location. Follow this and you’ll see your trophy/achievement pop in no time.
Chapter 1: The UAC
Collectible 1 – Once you obtain the Blue Access Key, jump onto the nearby crate then then proceed upwards onto the higher ledge where you’ll find this collectible.

Chapter 2: Resource Operations
Collectible 3 – This one takes a bit of work. When you get up to the point where you must realign a satellite, enter the above vent. Follow it to its exit then climb onto the nearby roof. Follow to the ladder and climb that, then enter the building you discover.
