RELATED: Horizon Forbidden West Review
By detaching components and defeating machines, players can purchase and upgrade powerful equipment that allows Aloy to take on even tougher challenges. While every resource in Horizon Forbidden Westhas its use at some point in the game, certain machine parts stand out as the most valuable the game has to offer.
10 Fire/Frost Claw Sac Webbing
The Fire and Frost Claws are among the most powerful machines in Horizon Forbidden West, with the Apex Fireclaw clocking in at 15 levels over Aloy’s maximum. Their Sac Webbing is one of the most widely utilized resources in the game, as many weapons and armor pieces require it for upgrades.
The challenging part about acquiring the Sac Webbing is that, unlike many other valuable machine parts, players will have to avoid destroying the elemental unit on the machine’s chest. Hitting this unit creates a massive, elemental explosion that deals massive damage to either Claw but removes the possibility of looting this vital resource.
9 Stalker Stealth Generator
The Stalker is a returning enemy-type from Horizon Zero Dawn, and its stealth capabilities are just as potent in the sequel. Disabling its cloaking tech isn’t easy, but players can remove the machine’s Stealth Generator with a few, well-placed arrows.
Not only will this eliminate the Stalker’s ability to disappear from view, but the detached Generator can be picked up for use in upgrading Aloy’s higher-level armor. Both the Tenakth Reaver and Tenakth Sky Climber sets need the Stalker’s Stealth Generator for their second enhancement tiers.
8 Scorcher Scanning Ear
The Scorcher Scanning Ear is a useful tool that Scorchers implement to track down previously seen enemies, even if they’re trying to escape or hide nearby. Targeting and removing the ear disables this ability while also allowing Aloy to recover the detached part for use in upgrading her gear.
The Scorcher Scanning Ear is a legendary-class machine part, and as such, can be found on the upgrade path of more than a few of Aloy’s high-level gear sets. The Utaru Protector is a rare, Survivor outfit that requires two of the parts for its second upgrade tier.
7 Tremortusk Tusk
The Tremortusk is one of Horizon Forbidden West’s most recognizable machines, and it has the power to back up its reputation. One of the most fearsome weapons at its disposal are the tusks it uses in a wide, sweeping attack that deals massive damage and knocks Aloy off her feet.

Each of the Tremortusks’ four tusks can be detached, significantly reducing the damage this attack inflicts and allowing Aloy to add the valuable machine part to her inventory. Tremortusk Tusks can be used to purchase and upgrade some of the rarest and most powerful gear pieces in the game.
6 Dreadwing Metal Fangs
The Dreadwing is one of the most fearsome enemies in Horizon Forbidden West, as it resembles a very large, stealthy bat that can shoot poison and turn invisible. It’s also one of the rarest enemies in the game, making its component parts even more coveted when buying and upgrading high-level gear.
The most valuable resource players can acquire from the Dreadwing are its Metal Fangs. Because they’re among the smallest, detachable components in the game, hitting the Metal Fangs with arrows can be a challenge while also avoiding the Dreadwing’s attacks. They’re used to upgrade many pieces of Aloy’s gear, though, so taking care to harvest them is worth the effort.
5 Thunderjaw Tail
The Thunderjaw is a machine Horizon veterans will know well, as it features prominently in both games in the series. It’s a walking artillery unit with multiple detachable weapons and powerful, physical attacks that are augmented by the large blade located at the end of its tail.
Fortunately, that blade can be easily removed with a well-placed arrow from any of Aloy’s bows. The Thunderjaw Tail can then be recovered as a valuable resource for use in all manner of upgrades for Aloy’s gear. Both the Sobeck’s Raiment and Tenakth High Marshal outfits require it for their upgrade tiers.
4 Stormbird Storm Cannon
The Stormbird is a powerful, flight-capable machine that returns from Horizon Zero Dawn. Its devastating shock attacks are powered by a Storm Cannon located behind a metal plate on its chest. Destroying or detaching the Storm Cannon disables these attacks, forcing the Stormbird to resort to a high-flying, physical assault.
If detached, the Storm Cannon can be recovered and used to upgrade Aloy’s weapons and armor, like the Utaru Protector outfit. Players should be careful where they shoot the Storm Cannon, though, as destroying the component won’t leave it available for collection.
3 Slitherfang Earthgrinder
One of the newest and most elusive monsters joining the series in Horizon Forbidden West, the Slitherfang is a monstrous, snake-like machine that can burrow underground with the help of the powerful Earthgrinders located on its body, just below its face.

The Earthgrinders are a tempting weak point, as they’re vulnerable whenever the Slitherfang raises itself to prepare an attack. Removing them doesn’t rob the Slitherfang of any of its abilities, but they are a highly sought-after resource that Aloy can use to improve many of the tools in her inventory.
2 Tideripper Tail Fin
The Tideripper is Horizon Forbidden West’s most fearsome, aquatic machine, capable of dishing out massive damage with its Purgewater attacks and the heavy blade attached to the end of its tail. This blade is one of the monster’s weak points, though, and shooting it off will weaken the Tideripper significantly.
The Tideripper Tail Fin is one of the most valuable resources in the game because of how many different armor sets require it for upgrading. Sobeck’s Raiment, Tenakth Reaver, and Utaru Protector all utilize the component to boost their stats and unlock new skills.
1 Apex Hearts
As players progress toward the more challenging content Horizon Forbidden West has to offer, they’ll encounter more of the Apex variety of machines. These are tougher versions of the standard enemies, and their enhanced nature means they also come with new and more valuable components.
Apex Hearts are the most useful of these, as they feature in just about every weapon or outfit’s upgrade path at one tier or another. There are no special instructions or detachable parts to focus on to acquire Apex Hearts, but taking down an Apex machine is more than enough of a challenge to test even the most skilled of players.
Horizon Forbidden Westis available now for PS4 and PS5.
