Hangar

The  is a location on board Mothership Zeta.

Layout
The Hangar is the part of the ship where smaller spacecraft enter and exit Mothership Zeta. When you arrive, you can see Recon Craft Theta enter through the hangar door in the floor. Within the Hanger is one of the generators that must be destroyed as part of the Among the Stars quest. If you requested his help, Paulson will follow you into this area. Once you get to the control center and activate a button, an alarm will go off alerting the aliens to your presence. Thus begins a rather fun battle using the gravity beams that hold up Recon Craft Theta. The upper level of the Hangar includes a console with five buttons; each button causes a pair of the beams to emit bursts of energy that send the Aliens and their Drones flying. This is both a fun and effective way to repel the waves of attackers; just be sure to place a few mines at the doors in case some Aliens find their way to you. (Bottlecap Mines are the most effective, especially with the alien shields.)

Notable loot
Unlike other portions of the ship, there is very little loot inside the hanger. Alien Crystals and Alien Epoxy are quite prevalent, and several Drone Cannons can be obtained from the Guardian Drones within. The two teleporter rooms in the eastern chamber contain many Alien Power Modules and crystals; same goes for the generator room.

Vaguely referenced above, on the shelves on the left side of the room where you'll destroy the generator, there is an Alien Disintegrator and 4 packs of Alien Power Modules or 200 rounds. There's a shock baton on the shelf below that.

After the battle, the previously blocked off rooms on the lower east side are open. The north eastern room has crystals and the south eastern room has 5 packs of Alien Power Modules and an Alien Atomizer.

Bugs

 * In the Generator Room at the 'end' of the area there is an inactive teleporter, if you look through this teleporter, you may actually get a 'Search Alien' prompt and be able to loot this seemingly nonexistent body.
 * When you go through the door that takes you to the control room, sometimes you can't walk through the door, as if the shield was still there.
 * You can get stuck once you get past the door and will have to restart it.

Appearances
This only appears in the Fallout 3 add-on Mothership Zeta.
