"Can feel the ground tremble beneath that mountain of a machine."
―Aloy nearing a Tremortusk

The Tremortusk is a machine in Horizon Forbidden West.

Appearance[]

The Tremortusk chassis is reminiscent of a proboscidean, most likely a mammoth based on its downward sloping back. Its face bears four articulate tusks tipped with impressive orange spades, a prehensile trunk, and a pair of Plasma Cannons, the latter of which rest beneath its eyes. Its back is lined with several long-range weapons: near the base of the head are a pair of shock cannons, which are followed by four antennae, and then a set of retractable salvo cannons in front of their rear hips. On its rear are four cylindrical ammo drums. Its belly contains a massive orange Blaze sac, with a smaller amplifying sac on its chest.

Standing several meters tall, the Tremortusk towers above humans, as well as many other Zero Dawn machines.

Behavior[]

Tremortusks can be encountered naturally in the wilds of the Forbidden West, but they can also be found under the control of Regalla's Rebels. Rebel Tremortusks are specially outfitted similar to war elephants of old, making them an even greater threat. After a certain amount of damage, it will rear up and throw the humans off its back. It also tends to charge at the player.

Like most machines of its size, the Tremortusk is largely solitary, and is only rarely found in groups of two.

History[]

The Tremortusk was designed by HEPHAESTUS for the task of culling the human population, specifically hunters attacking the terraforming system's machines.

During Regalla's rebellion, the rebel forces managed to override Tremortusks and add them to their forces. Due to their size, the overridden Tremortusks were outfitted with war huts that would enable a rebel group to fight from atop the machine. One such Tremortusk was felled by the Easterner Aloy, who used one of its cannons to bring down the Bulwark.

Abilities[]

The Tremortusk is effectively a walking tank, bearing a barrage of long-range weaponry that enable it to attack from nearly any angle or distance. Its trunk can be used to spray fire on enemies, or itself and allied machines with amplifying gas. While generally slow-moving, it is capable of occasional bursts of speed, including wide swings of its massive head and tusks. These attacks, combined with heavy armor plating, make the Tremortusk one of the most formidable enemies to encounter in the wild.

Some Tremortusks are equipped with antenna, giving them the ability to summon machine reinforcements.

Weaknesses[]

The Tremortusk's Blaze sac is its primary weak spot, due to its large size and relative ease in access: destroying it will inflict the burning state, as well as disable its fire attacks. Its Plasma Cannons can be detached and used against it, although the Apex variant's Plasma resistance makes this hardly effective.

Because the Tremortusk has few attacks that can reach targets above it, it can be relatively safely attacked from a ledge above it.

Trivia[]

  • This is the first combat class machine to be revealed from Horizon Forbidden West.
  • The machine catalog and official guide do not state that the standard variant of the Tremortusk is resistant to Shock, despite a Focus scan and a trial at Hunting Grounds: The Raintrace showing its resistance.
