How to unlock the King of the Crystals achievement in DOOM Eternal - Definitive Guide
Before you start be sure you select Extra Life mode so we can get the achievement for finishing that with more than 10 lives (Guide shows all Extra Life locations as well!).
Of note, nothing is missable you can replay missions to get anything you missed, and also you will be given the option at the end of levels to warp to specific sections to grab anything you missed which can alleviate having to play the entire mission again. Every collectible and item will be time stamped in the video comments and description!
**IF you are following my guide to get all campaign related achievements in one playthrough then MISSION SELECT IS NOT AVAILABLE IN EXTRA LIFE MODE. So if you miss a collectible be sure to use the Fast Travel Function near the end of levels to grab anything you missed!!**
**This particular achievement is tied to finding the Sentinel Crystals, which are timestamped in the videos if you just need those. The achievement will unlock upon fully upgrading either health, armor, or ammo (I prefer health and ammo first, but what you decide to upgrade is dependent on your play style. You will eventually have enough crystals to fully upgrade all of them.**
I hope you find it helpful!

Should we focus only on 1, or will we eventually earn 16 sentinels to unlock all HEALTH, AMMO & ARMOR upgrades?
Which should we focus on first?
Which should we max out first?
Does difficulty matter?
Throughout the game you will find Crystals, one of which is found in the Fortress of DOOM near the beginning of the game and it is a mission objective to collect it, to show you what they are. Each of these will allow you to upgrade either your Health, Armor or Ammo by 1. Each of these has 4 total upgrades, so for this achievement you will need to collect a minimum of 4 Crystals and concentrate on upgrading the same thing, however there are enough Crystals to fully upgrade everything and when searching for this games many collectibles, these will be found along the way.
See the description for "Gunpletionist" for a video of all the games collectibles in every level, including the Crystal locations.

By collecting them you can level up to 100%.
To achieve this you need to find all Guardian Crystals.
