Guard batteries guide

In the 13 missions of Doom: Eternal you can find several guard batteries. They help you to supply parts of the Fortress of Doom with energy and to unlock useful improvements or different skins. In the following table we show you how many guard batteries you can find in the respective missions:

hell of Earth: Number No
Exultia: Number 1
Cultist base: Number 3rd
Doom Hunter base: Number 2nd
Super blood nest: Number 3rd
Arc complex: Number 3rd
Martians: Number 3rd
Sentinel Prime: Number No
Taras Nabad: Number 3rd
Necravol: Number No
Necravol - part 2: Number No
Urdak: Number No
Final Sin: Number No

Apart from that, you have another option to unlock guard batteries. Every mission comes with three challenges. For example, you have to collect a certain number of code entries, erase certain demons with different weapons or perform different glory kills on selected opponents. For each challenge you complete, you will receive a guard battery at the end of the mission.

Using collected guard batteries

In the Doom of Fortress you can use the collected guard batteries to further strengthen your weapons or armor. With the weapon mods you can equip a weapon of your choice with a new modification. Praetor suit points, on the other hand, strengthen the capabilities of your armor, but can also influence the environment. With the extremely useful Guardian Crystals, you can increase your maximum ammunition stock or incorporate more health and armor.

Skin: Classic Doom Marine
