ARC Complex is the sixth level of the campaign in Doom Eternal.
At the end you face a Marauder as a mini-boss fight. It doesn't count as an official boss fight so the level does contain a Slayer Gate and Secret Encounters. The final Field Drone is also found in this level.
Description

Unable to identify his position due to the Khan Maykr's interference, you travel to the ARC Complex, headquarters of the Armored Response Coalition (ARC), in search of Dr. Samuel Hayden, leader of the human resistance on Earth and the only person capable of finding the final Priest.

- It is the third ruined-urban level, with a twist of occurring at night and with less Hellification, as it used to be the headquarters of the Earth resistance ARC.
- The UAC claimed to have killed Dr. Hayden at the beginning of the level, but near the end the Slayer finds he was simply dismembered like C-3PO in The Empire Strikes Back.
- In a part of the level in a room full of purple goo, an alligator can be found relaxing under a platform in the goo. It is a harmless prop and easter egg.
