UAC announcer

The UAC announcer is an automated/computerized female voice presenting 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. It delivers clues to the player about his next mission and provide warnings about environmental hazards that the player may encounter. The same announcer also occurs in the Resurrection of Evil expansion.

A different announcer with the same purpose can be heard in the Exis Labs during The Lost Mission.
