The cargo hold is accessible through a door on the east side of the engineering core just south of the door to the hangar. The cargo hold is an area of the ship which the player character does not have to visit in order to complete the storyline of Mothership Zeta, but due to the wide variety of items housed on its floors and shelves, is a worthwhile visit. A unique and potent variant of the plasma pistol, the MPLX Novasurge, is obtained here. The cargo hold appears to be where the aliens store and catalog technology abducted from the Earth, from empty soda bottles to missile launchers. This huge cache of familiar tech, weaponry, and clutter from the game proper is guarded by guardian drones and alien turrets.
It consists of a large conveyor belt, one upper and a few lower walkways, and a disposal area. To the left of the entrance from the Engineering core is a locked door (which is unlocked from the other side in the research lab) concealing a teleporter to the research lab. To the right of the entrance are three alien containers.
The floorplan is roughly square with a main floor, slightly elevated maintenance walkways above the labyrinthine conveyor belt (non-operational), and a higher walkway grid which oversees the entire room. There are several 'lobes' on the ground floor, roughly categorizing the huge stockpile of earthly artifacts, some in large numbers, on shelves which line almost every wall.
All stairways lead to the ground floor, with none bridging the lower and higher walkways. but it is often an easy jump from the higher walkway to one of the lower ones. Jumping into the waste disposal chute is instantly fatal. There is a healing archway in the easternmost southeast 'lobe', on the upper walkway. A door to the research lab is in the southwest corner.
Not to be confused with the named sub-level of the maintenance level, waste disposal, this corner of the cargo hold is where the aliens discard examined material by disintegrating it in an electrified chute. East of the chute is Underwood's safe, which contains the MPLX Novasurge. The safe is unlockable via Reid Underwood's terminal (Hard encryption), which is in the southwest area of the cargo hold (the only active terminal).
