Map of Alien Ship
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets.


Head forward into a large room; the entrance will be sealed behind you. Collect all the supplies in this room, then throw the switch behind a low wall on the east side to open the way forward and release four reavers. Head north and go down the steps; the wall in front of you will lower to reveal a large cavern with numerous enemies including an inquisitor; using the Sigil will allow you to destroy it quickly, and its bolts may eliminate other enemies in the cave. It is also possible for the inquisitor to fall down the deep pits here from where it will struggle to escape.

Once the path is clear, head across the bridge between the pits and through an opening in the wall to the north. Follow the tunnel through to a green passage and destroy two stalkers waiting here, then lower the lift and ride it down to the bottom floor. Go through either of the sliding doors ahead, then follow the bridge to another set of sliding doors. Open them and head forward to the Entity's lair.

Other points of interest[edit]

After stepping on the lift leading to the large bridge, let it take you up to the top floor. The tunnel here leads to a small room with healing items.



There are no official secrets on this level.


  • After going down the large lift and entering one of the two green doors, you will find a long room. The bridge on which you stand is damaged in front of you. To the north of the damaged section, there are many black steps. Use them to get to the northern edge of the room. Be careful not to fall off, as the ground where the steps stand causes an instant death. The five green lights on the northern wall are actually doors that lead to a long passage. The area holds seven energy packs, five medical kits and two surgery kits.


Two things (143 and 144) use the invalid type 0 but also have no flags set for any of the three difficulty classes, so they do not actually appear in the level anyway.
