DOOM

Just a note to let people know "A single campaign run" isn't what it sounds like.

There is full mission select support with the progress saved.
The single run business means on one save (you can have up to 3).

Doom has over 200 collectibles (79 Secets, 49 Data Logs, 36 Elite Guards, 26 Collectible Doll Models, 12 Rune Trails, 12 Field Drones, 11 Argents Cells, 13 Automaps). All collectibles are saved immediately when picked up. Collecting everything will reward you with more than 10 achievements. I have created 100% collectibles guides for each mission. In this guide I will only link to the Argents Cells.

If you are interested in the complete guides containing links to every single collectible you can find the playlist here.

For this Achievement you have to collect the 11 Argents Cells in the Game. (1 Cell get you automatically during the story). Argents Cells are tracked in the right lower corner under Exploration when you hit the button. You can get Argents Cells via chapter select at any time.

The achievement says "a single campaign run" and means on one savegame. You can create 3 different savegames in Doom. Make sure you collect and upgrade all on the same savegame and all is fine for your achievement.

DOOM contains -
- 79 Secrets
- 26 Collectibles
- 47 Data Logs
- 36 Elite Guards (Praetor Suit Upgrades)
- 12 Argent Cells (Health/Armour/Ammo Upgrades)
- 12 Field Drones (Weapon Mod Unlocks)
- 12 Rune Trials (Rune Stones)

The pickups are scattered across the all 13 available campaign levels and are saved immediately after being picked up. In order to max out your health, armor and ammo in one run, you must find all 12 available argent cells and equip them. NOTE: "One run" just means that it must be done in a single save file, so mission select is totally alright.

A complete guide for 100% for the game that shows these locations can be found HERE.
