The messages give clues to the player about his next mission and warn about upcoming environmental hazards (i.e. automated turret guns online). However, some of the 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. MARS CITY "Shuttle Delta Tango 1-4 preparing for departure." - UAC Announcer "Attention: Director Banks, please report to Central Administration." - UAC Announcer COMMUNICATIONS CPU
