ROCKBREAKER (HORIZON ZERO DAWN)
Horizon Zero Dawn (2017)
The Rockbreaker is a machine in Horizon Zero Dawn. Highly durable and capable of rapid movement on the surface or underground, Rockbreakers are one of the largest and most formidable machine types.
The Rockbreaker most closely resembles a badger or a mole with a flat and durable body, broad shoulders, and powerful front legs, although, unlike such creatures, this machine has a tail making up about a quarter of its length.
Its most prominent feature is the massive maw of a tricone roller drill mounted on its head, each drill bit is set on jaws to allow the mouth to open and close. It is a quadruped, the front pair of legs sporting huge claws. Under the machine’s belly is a fuel sac filled with Blaze, and an exhaust port is positioned atop the body at the base of the tail.
Rockbreakers seem to be one of the original Acquisition-class machines created by GAIA to terraform Earth after its sterilization at the hands of the Faro Plague in the mid-21st century. They have likely been around since before humans reappeared. While other mining machines like Lancehorns are able to gather materials from the surface, the Rockbreaker can tunnel deep into the earth to gather valuable raw materials for use in the Cauldrons.
After the Derangement, an event which caused all the existing machines to become more aggressive towards humans, the Rockbreaker’s frightening speed, rugged design and powerful tools made it a menace to any humans nearby. By the time Aloy learned to hunt and fight machines, Rockbreakers would attack any human they detected.
