Doom 3 maps

Mars City: Union Aerospace Corporate Division is the third level of Doom 3. It is the same level as Mars City, but after the demon invasion. In this level, the marine must return to the Marine Command, where he is then given his mission to link up with Bravo Team in Alpha Labs, then have to travel through Administration. This is where the demo ends.


Notable features of this level include :

  • Picking up and using a Keycard ; the pick-up sound is the same as in original Doom.
  • Getting the Machine Gun from Z-Secs if you didn't found it in previous level.
  • Infirmary.
  • Water closets, with the infamous mirror scene.
  • The first trip with an helping Sentry Bot.
  • Passing in front of a closed Monorail Station door.
