Mission 4: Argent Facility is the fourth campaign mission in Doom 2016. The main objective for this campaign mission is to shut down the Argent Tower by disabling Argent Filters.
In this mission you’ll be able to collect a brand new devastating close range weapon Super Shotgun from demons. You’ll come across well hidden collectibles like field drones, data logs, automap station, hidden rooms, elite guards, argent cells, and rune trials (this type of collectible makes its first appearance in this mission). Some of them give you upgrade currency, while others do nothing but clue you in on the story. This guide will show you all mission 4 secrets & collectibles in Doom 2016 and where to find them.
