Site 03

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)

Introduction
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. 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.
