Horizon Forbidden West follows right after Zero Dawn, and it features several new machines that Aloy will come across. The Bristleback is one of the new machines from the Forbidden West, and players will need to know how to defeat them to harvest materials and resources.

In Horizon Forbidden West, every machine has specific weak points and is often vulnerable to special elemental damage. Bristlebacks have a sturdy body, but there are a few weak points: their Grinder Discs, Acid Canisters, and Tusks. It is also weak against Shock-damage attacks but resists Acid-damage attacks.

It is ideal to detach components like the Grinder Disc and Acid Canisters from the Bristleback by hitting them with Tear-damage arrows. Alternatively, use Acid arrows to target the Canisters to create an explosion. The following components are available after defeating Bristlebacks:

Defeating the Bristleback without detaching its components first will not reward players with the best loot. Similarly, using Silent Strike on Bristleback destroys these detachable components and removes them from the loot. To override Bristleback, players will need to visit Cauldron TAU located near Plainsong.
