UAC announcer

"Welcome to Mars City, Union Aerospace's premier research facility. To expedite your processing, please proceed directly to reception."

- The UAC announcer

The UAC announcer is an automated/computerized female voice that presents numerous messages at various locales during the Doom 3 single player campaign. It is first heard at Mars City and for the last time in Delta Labs - Unknown: Union Aerospace Research Division

The messages are often used to give clues to the player about his next mission as well to warn about possible upcoming environmental hazards (i.e. automated turret guns online). However, some of these messages heard are quite ironic. For instance, when the Marine heads over to a bathroom in Mars City after the demon invasion, the announcer may state that the UAC offers psychological care, after which the player is then subjected to a brief hallucination.
