This article is about Doom (2016) level. For the location in Doom 3, see Site 3.

Site 03, also referred to simply as The UAC, is the first level of Doom (2016). The first mission, Rip & Tear, begins in this level and continues into the Martian Outskirts. The Doom marine awakes from his slumber to find himself trapped in a holding facility overrun with demons and possessed personnel. He quickly reclaims his Praetor suit and begins picking up weapons, beginning with the pistol and combat shotgun. This level is divided into two sections; after completing the introduction section, the player will instead start at the second section.

"So you walk eternally through the shadow realms, standing against evil where all others falter. May your thirst for retribution never quench, may the blood on your sword never dry, and may we never need you again."
― Corrax Entry 7:17 (Loading description)

Mission 01: Rip & Tear[edit]

After waking up from his sarcophagus, the player is tasked with finding the way to Resource Operations so the satellite array can be reactivated.



After the short cutscene and picking up the pistol, you will be attacked by a few possessed scientists. After dealing with them, head to button which will activate a holographic echo recording of several scientists bowing down to your sarcophogus, with the top part being a hologram. Olivia Pierce will appear briefly, remarking that they cannot allow your sarcophagus to be opened. Head to the door next to the button to pickup the Praetor suit. Then head east and you will find several possessed scientists blocking the way; this section serves as an introduction to glory kills, which will restore health upon a successful execution.

Head straight and pickup the combat shotgun; you'll then encounter an imp shortly thereafter. Continue onward and you will encounter the game's first gore nest. This gore nest needs to be destroyed in order to advance. After destroying the nest, a wave of imps will attack. Defeating them all unlocks the next gate and an elevator. Heading to the elevator will start the next cutscene and end the first part of the level.

Note that this tutorial section of the level is entirely skipped when replaying the level from the campaign menu, when playing in the Ultra-Nightmare skill level, and when playing in arcade mode.

Blueguy Combat shotgun After acquiring the blue key from the dead captain, jump onto the crate behind him and then turn around 180 degrees and look up slightly. There is a cliff ledge just above and in front of the captain. Jump up and grab the edge of the ledge to find Classicguy on top.
Classicguy Imp Just before the final area of the level, while passing under the damaged railway bridges, take the lower canyon-like passage to the left. As you reach the end, without jumping up toward the green armor above, turn around and follow the wall behind you into a small cave. The cave exits out onto a view over a deadly fall zone. Blueguy can be found just in front of the precipice. It is just barely possible to jump to this precipice from the lower area to the side, but the risk is unnecessary.
