The Bone Thresher is an armored eel-like monster from the Depths of Europa, commonly seen alongside groups of Tiger Threshers.

Description

Bone Threshers are moray-like creatures with a rough, heavily armored body, a gaping maw and two small lateral fins. Their body is heavily protected by large plates of bone-like armor (giving it the Bone Thresher name). Like their smaller relatives, Bone Threshers have no visible eyes and a jaw filled with many razor-sharp teeth.

Bone Threshers can be found alongside pods of Tiger Thresher, in groups of up to three individuals (depending on the difficulty).

In-Game

Bone Threshers are capable of doing heavy damage to the hulls of a submarine with a single attack, and are fast for their size (albeit not as much as their smaller relatives). They will prioritize chasing after light and will mercilessly hunt any other living creatures by inflicting heavy bleeding on their prey with their jaws.

Bone Threshers can not enter the Submarine due to their bulky body, preferring to make major hull breaches to allow Tiger Threshers to enter.

Combat Strategies

Railguns are the preferential way of dealing with a Bone Thresher. However, they can take more than 3 shots, so it's recommended to load the Railgun Shells with C-4 Blocks or heavier loads if available and to focus fire on their unarmored head. Bone Threshers are the anchor of Thresher swarms, and dispatching them will greatly increase your chances of survival. Alternatively, the Coilgun utilising Piercing Ammunition can quickly neutralise the threat.

It is highly advised to avoid close quarters combat with a Bone Thresher. If it is unavoidable, the Autoshotgun utilising Explosive Slugs, or the Boarding Axe are both recommended weapons to use.
