DOOM Eternal: All Collectibles Locations | M8: Sentinel Prime

Doomguy discovers his past in M8: Sentinel Prime — and fights a titanic demon gladiator. This is a quick mission that’s packed to the brim with collectibles. Most of them are super easy to locate, but like every level, some are hidden in secret spots. If you’re lost and need an extra nudge to grab those missing items, we’ve got all the locations listed below.

The backstory of DOOM Eternal is both essential and completely unnecessary. We know why Doomguy kills demons — it’s because they’re demons! But, if we didn’t get the flashbacks in this mission, we wouldn’t get to experience the awesomeness of Doomguy talking. Yes, Doomguy finally speaks in this missions. It was worth the wait.

How Collectibles Work In DOOM Eternal:

There are many different types of collectibles in DOOM Eternal: Automaps, Runes, Praetorian Points, Weapon Mods, Albums, Cheat Codes, Toys, Sentinel Crystals and Sentinel Batteries. Every level features an Automap, but not every level will have albums, toys, cheat codes, or Slayer Keys.

Basically, there are a ton of different collectibles, and below I’ll list where to find them all — in order from the beginning of the level to the end. Levels in DOOM Eternal are much more linear, so as long as you follow along, getting every collectible is easy.

  • NOTE: To make finding collectibles easier, select the “?” Praetorian Suit upgrade for 3 points — it will cause every collectible location to appear on your map.
