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.
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, unlockable via Reid Underwood's terminal in the Southwest area of the cargo hold.
