Engineering Core

The  is a location on board Mothership Zeta.

About
The Engineering Core is the third area that the player encounters aboard the Mothership, and serves as a hub between numerous other locations aboard the ship, including the Steamworks, Hangar, Cryo Lab, Robot Assembly, and Engine Room. Here, the player can also find several other captives who will assist the player aboard the ship. As the player progresses through the Mothership Zeta quest, the Engineering Core changes. Defenses are put up and barricades are made by the other captives. Eventually a broken Nuka-Cola Machine will show up. A Teleport to Bridge appears near the Steamworks entrance, down a corridor to the left of the Nuka-Cola machine.

The Engineering Core is one of the few rooms still available to explore after This Galaxy Ain't Big Enough... quest is complete, as most other rooms beyond it will become inaccessible. At this point, aliens will also begin to spawn occasionally in the room.

Third Home
is an excellent place to store items worth keeping but that the player doesn't wish to always have in inventory, and is much safer than using abandoned houses in the Wasteland. Aliens do not steal items, so leaving unique weapons in cases or even on shelves comes with no risk of thievery. This is useful after the This Galaxy Ain't Big Enough... quest is complete and the player is given control of (parts of) the ship. The ship is simply an alternative and only for asthetic purposes.

Notable loot

 * A Buttercup Toy on the table near the windows, and on the floor above near the powered down tele
 * A minigun in good condition can be found against the wall to the right of the door to the decompression chamber
 * Several ammunition boxes with various non-alien amno like 10mm, 5mm, or 5.56mm
 * After the quests have been completed, two Aliens can be found here, wielding an Alien Atomizer and Disintegrator, along with Alien food/ammo. They respawn every few game days. This can be a good way to to replenish your supply of Alien Power Modules. ( Xbox 360 and Pc confirmed ).
 * In the hall leading to the Engineering Core's lower floor there is a Chinese Commando's hat.
 * 26 Alien Power Cells can be found here in a box along with a Nuka-Cola Quantum and three turpentines. This crate appears near the Alien workbench after exploring all of the rooms branching from the Engineering Core and destroying the generators or after performing the spacewalk.
 * 2 Nuka-Cola Quantums appear in a crate with a Nuka-Cola next to a generator and rusty tricycle after exploring all of the rooms branching from the Engineering Core and destroying the generators.
 * 1 Nuka-Cola Quantum appears next to the workbench in a wooden crate with Turpentine in it after exploring all of the rooms branching from the Engineering Core and destroying the generators.
 * 1 Mini Nuke appears in the chair next to the workbench in the room that leads to the Decompression Chamber after exploring all of the rooms branching from the Engineering Core and destroying the generators.
 * 1 Nuka Grenade in a crate near malfunctioning control near bed

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

Bugs

 * A floating turpentine can be found in the room where the captives wait for you near the door at the bottom of the stairs (Xbox and PC). It is supposed to be on top of the generator that appears here later.


 * The teleporters on this deck may stop working, while displaying the appearance of a fully active teleporter; attempts to activate them only result on a no interaction tone. This can be a fatal game glitch permanently trapping the player on the ship. as a precaution one should save on the bridge before returning to the engineering core. (Unconfirmed)
