Transport Class machines
Behemoth
The Behemoth is a machine in Horizon Zero Dawn. It is a large Transport Class machine, inarguably the largest and most powerful known machine of this class. Its primary purpose is the collection of resources from smaller Acquisition Class machines and the transport of these resources to cauldrons for machine manufacture. It collects these resources using its anti-gravity technology. With the onset of the Derangement, this technology is used by the machine for lethal attacks on any human it encounters.
Fire Bellowback
The Fire Bellowback is a machine in Horizon Zero Dawn. It is a dinosaur-like medium-sized machine of the Transport Class. It is one of a pair of “twin” machines; the other machine in the pair being the Freeze Bellowback. Presumably, Fire Bellowbacks functioned to clear away large tracts of land by burning as part of Zero Dawn terraforming operations, as well as transporting large amounts of Blaze, presumably to cauldrons as fuel.
Freez Bellowback
The Freeze Bellowback is a machine in Horizon Zero Dawn. It is a dinosaur-like medium-sized machine of the Transport Class. It is one of a pair of “twin” machines; the other machine in the pair is the Fire Bellowback. Presumably, Freeze Bellowbacks functioned as fire extinguishers alongside Fire Bellowbacks to control the fires they set to clear away large tracts of land by burning as part of Zero Dawn terraforming operations.
Shell Walker
The Shell-Walker is a machine in Horizon Zero Dawn. It is a medium-sized Transport Class machine, primarily functioning in the transport of resources gathered and processed by other machines to cauldrons. However, it was weaponized at the onset of the Derangement, and now poses a significant threat to any human who encounters one.
