|Release date||18 April 2017 (Update)|
Brothers In Arms is an achievement that requires the player to deal the killing blow to each of the Barrows brothers with their own weapon.
- The achievement name is both a reference to the idiom "brothers-in-arms", meaning a group of soldiers or warriors who fight on the same side, and a play on the word "arms", short for "armaments", which is a synonym for military weapons, a reference to using each warrior's weapon against them.
