Mars City (Location)

Mars City is a base of the UAC located on Mars. The UAC constructed it 25 years ago before the events of Doom 3. Higly trained Marines and a new unit called Mars-Security, regular guards of the base were protecting it. The events of Doom 3 takes the player to the base. The same day that the Demons invade the base. Most of the Mars-Security Squad were transformed in Zombie-Security and the marines begin a Gunfight with the Demons, with unsuccesful results. With that the Radio becomes silence and the player is the only marine alive.
