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
It should be noted that the Engineering Core is an excellent place to store items and anything else worth keeping that you will not want to always have in your inventory and it is alot safer than finding abandoned houses to do so. Aliens do not steal items, so leaving unique weapons in cases or even on shelves do not come with the risk of thievery. This comes into play after This Galaxy Ain't Big Enough... is complete and you are given control of the ship. The ship is simply an alternative and only for asthetic purposes.
