Burrower

In Horizon Forbidden West, Cauldrons are automated machine factories that, when completed, allow you to sabotage (hack) new types of machines to fight alongside you or serve as a mount.

There are a total of 6 main Cauldrons in the game. Some are part of the main story, while others are optional.

The world of Horizon Forbidden West is a vast and vibrant post-apocalyptic open world that expands the frontier westward across the US. It features diverse ecosystems, from tropical rainforests and arid deserts to submerged ruins and snow-capped mountains. It is notable for its ecological depth, with wild machines interconnected with the environment and realistic wildlife.

Diverse environment: The map includes deserts, coasts, jungles and mountains, offering great visual and gameplay variety.

Verticality and exploration: The game emphasizes exploration, allowing the player to dive into underwater ruins and climb challenging terrain.

Tribes and settlements: The world is inhabited by various tribes (such as the Nora, Tenakth, Utaru, Carja, and Oseram) with their own settlements, cultures, and mutual distrust. Nora: Most of them are Hunters. Brave. Defiant. Challengers. Utaru: peaceful, reclusive, vegan, reserved, kind, gentle. Religious, conservative, and traditional. Most are farmers and gatherers. Tenakth: hostile, aggressive, fierce, protective, warlike, dominant, loyal. Carja: Extroverted, tenacious, fun, friendly.

Interconnected machines: Machines are not just enemies, but part of the ecosystem, with behaviors that affect the environment.

"Living" nature: The design of the environment is another character, showing credibility with details such as daily life in the settlements.

Personality

Curious and playful: They behave similarly to otters or weasels, showing great energy and flexibility.

Fierce Sentinels: Despite their small size, they are aggressive and usually attack with high-pitched sounds and, in the case of certain types, with sonic attacks.

Highly mobile: They burrow underground and return to the surface to confuse hunters, making them more elusive and harder to catch than larger machines.

Cooperative: They are rarely alone; they work in groups of 3 to 5 to ambush their targets.

Behavior

Diggers behave much like lookouts, generally traveling in groups and often serving as lookouts for other machines. Diggers can emit high-pitched sounds to alert allies and stun enemies. They can also dig underground tunnels to reappear in unexpected locations.

Talent

Compared to the Watchers, their eastern counterparts, the Excavators are far more agile and maneuverable. They are amphibious, being one of the few machines capable of swimming and seeing underwater, and can burrow underground to reach a vantage point. As reconnaissance vehicles, Excavators emit a high-pitched screech when they detect a threat, allowing them to call for reinforcements. Therefore, while not particularly dangerous on their own, they pose a significant threat when accompanied by more powerful machines.

Weaknesses

Like the Watcher, the Digger's eye is extremely vulnerable to damage; one or two shots are enough to kill it. Its other weak points, such as the Sound Blade on its chest or the component on its back, are relatively easy to hit.

Appearance

The Excavator is a quadrupedal machine, similar in appearance to a mink. It has an elongated body, a long, pointed tail, and short limbs, each ending in four claws. It possesses a monocular array of five optical sensors, consisting of a large central blue primary eye surrounded by four smaller ones; its head is covered in armor plates. A rectangular resource container rests on its hind legs. Its chest is covered by an oblong component called an "acoustic shell."

The color of the light in your eye indicates your condition: Blue: tranquil, peaceful, calm Yellow: alert, wary, suspicious, cautious. Red: Danger, threat, hostility, aggression.

The Canister and Tracker Burrower variants are virtually identical to their standard counterparts, with two key differences: the armor around their eyes is equipped with three grinding components, while the resource container is replaced with a standard elemental container and a trapezoidal Tracker sprayer, respectively.

In their quadrupedal stance, the diggers are shorter than an adult human, although their length is approximately that of a watchman and therefore taller than an average human.

The excavators were designed as reconnaissance-class machines in the Tau Cauldron, with three standard variants: the standard excavator, the container excavator, and the crawler excavator. They can be found in Daunt and the Clanlands, and at the start of Forbidden West Horizon, near Sunfall.

Aloy and Varl first encountered the Diggers at the Far Zenith Launch Facility. Aloy later passed by some near Sunfall, and encountered them several times in Daunt and the Clanlands, including their new Apex variants.
