MAP13: Outpost Facility (named Area Zone on the automap) is the thirteenth map of Three's a Crowd. It was designed by Scypek2 and uses the music track "Red Alert" by Zachary Stephens (Ribbiks).

Other points of interest[edit]


  1. Press the blue switch at the west side of the map, then return to the blue key room and take the northwest corridor. In the next area with a rocket launcher, press on a wall to the south to get a backpack. (sector 30)
  2. In the room with two doors, one of which is the red door, open the south door and use the switch. This lowers the lift to the north, but also if you take the northeast exit out of the room, you can get a chainsaw from the lift nearby. (sector 150)
  3. Ride the lift with the chainsaw at Secret #2 up, then press on the north wall to find another switch. Flip it and take the east door out, then quickly enter the southwest passage before it closes. Press the switch to reach an outside area with a soul sphere and a megaarmor. (sector 154)


Three multiplayer-only things – a super shotgun (thing 340), a plasma gun (338), and a BFG9000 (339) – have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
