Argent Facility

The Argent Facility is the fourth level of Doom (2016). It contains filtration and processing devices for Argent energy, which is collected through the Argent Energy Tower. The fourth mission, Beginning of the End, takes place here. This mission uses the music track "Harbinger".

"Olivia Pierce, the cult leader of the UAC, is trying to open a gateway into their dimension. She wants to help bring about the end of this world, another lost soul, fallen under Hell's control. Olivia overclocked the Argent Tower, using it to drill a hole into the Hellscape and let Hell's army through. You need to shut down the Argent Tower before it breaks through into their world by disabling the energy filters located throughout the surface complex."

Mission 04: Beginning of the End
To stop Olivia opening a portal between Mars and Hell, the Doom marine must disable three induction filters in the Argent Facility to cut the flow of power to the Argent Energy Tower, followed by the Argent processor. Although Samuel Hayden instructs the marine to carefully remove the filters, he instead destroys them to prevent them being used again, much to Hayden's consternation. After the marine destroys the final processor, VEGA reveals that Olivia has reached the Argent Energy Tower and taken an accumulator from its base; the marine heads there at once to stop her.

Objectives

 * Shut down the Argent Tower
 * Disable the Argent filters (0/3)
 * Disable the Argent processor


 * Kill Olivia Pierce

Essentials
Go through the door in front of you and turn left to find a plasma rifle and ammo, then go up the stairs and follow the path past a UAC Spokesperson to another airlock door; press the panel on your right to open the door and go outside, then turn left to see a gap in the fence and walk through it to drop to a ledge below. Jump across to the column in front of you and use the rock ledges next to it to reach the second floor of the column, then jump over to some metal bridges leading to the first rune trial of the game where you can obtain the Vacuum rune. After completing the trial, turn left and follow the path to a door which opens automatically, then turn left and follow the passage past some hanging corpses to find a dead soldier holding a rocket launcher. Head straight forward and go round the corner to a door leading outside, where you can practice using your new weapon on several imps and possessed soldiers followed by a Hell knight. Jump over the wall that the knight came over and turn left to see more imps along with possessed engineers, then head past them to find a gore nest that will release two waves of enemies; imps and a knight, followed by more of the same enemies along with soldiers. Once the nest is destroyed, head up the nearby slope to a door and walk through it, then turn left to find another door leading to the first Argent filter. There is a health station in this room as well if you need it.

After destroying the first filter, go back outside then turn left and head straight forward to a large sealed door; turn right at this point and follow the sandy path in front of you to a small door with a green light that you can walk through. Behind the door is a tall room with blue plasma pipes containing another gore nest which is protected by imps and Hell razers; after pulling out the nest's organ, turn left and use the boxes to climb up to a ledge with a Haste powerup that will give you an advantage over the various enemies that teleport in. Once the nest is destroyed, go through the door to its right to find another health station then turn left to see the second Argent filter in front of you next to another rocket launcher. After destroying the second filter, go back to the plasma room where you will be confronted by a summoner; this opponent calls in other enemies to fight alongside it and teleports frequently, so use the trail of red energy it leaves behind to identify its position.

Once the summoner and all its backup have been slain, cross the bridge that was behind the gore nest and head down some steps to a door leading back outside. Head straight forward and follow the sloped path up to a third gore nest guarded by a razer and soldiers; attacking the nest will cause razers, imps and knights to appear as well. Go up the slope near the nest to a door and pass through it, then turn left and follow the path to a second door which has the third and final Argent filter behind it. Once this filter has been destroyed, leave the room and turn right to enter a garage. Walk past the parked trucks and force open the door ahead, then turn left to go through another door leading to the fourth gore nest which is guarded by soldiers and razers; after attacking the nest, make sure to grab the Berserk powerup in front of you to slay the knight and summoner that appear. Head through the large doorway past the nest and turn right to find an airlock, cycle it then head through the next door to find the Argent processor. After destroying the processor, turn left and head into the next airlock then cycle it to finish the level.

Challenges

 * Walk the Path
 * Interact with a rune trial stone.


 * Bird's Eye View
 * Acquire the automap for the Argent Facility. To find the automap station, enter the plasma room just before the second Argent filter and look for some wall fans on the first floor. Go past these fans to find a door that must be forced open; the automap station will be in front of you along with a heavy assault rifle.


 * To Be Knighted
 * Perform two "Death from Above" glory kills on Hell knights.

Classic level
The lever that opens the classic area is hidden next to datapad #1 (see the "Other items" section below), next to some barrels. After pulling it, continue to the next passage full of hanging corpses to find that a door in the right-hand wall has opened, and behind this door is the entrance area of Doom's ; there are no enemies to fight but the armor bonuses and stimpacks can be picked up if you need them.

Special items
After leaving the plasma room, immediately turn right to see a gap in the fence with a dark path behind it. Follow the path until you find an engineer and scientists guarding a super shotgun.
