Added by the AvP : Humans module is the Quarry. Whilst the Quarry itself isn’t a block or device the player makes, its instead a creation that comes as a result of using the Quarry Terminal to establish a work area and having the frame be finished. Seen below is the main segment of the Quarry.

The Quarry itself pushes itself down using multiple shafts as it mines further and further to its target Y-Level. Additionally, the mining plate on the bottom of the Quarry can be seen visibly spinning whilst working. When multiple chunks are chosen to be mined out the Quarry will first reach the bottom of its first target, retract back into the Quarry and then move over to the next.

The Quarry itself doesn’t hang, rather its connect through four separate Gantry Shafts. These allow the Quarry to move across the entire frame in an omni-directional movement.

Note - Quarries do not damage mobs! They aren’t intended to be “weapons” and as a result will never be changed to be able to mine out Xenomorph hives and future structures.
