Developed in antiquity, this weapon is nevertheless quite prevalent in the post-Great War wastelands.
Brass knuckles take the form of four linked metal rings in a shallow convex formation with a bumper attached to the concave face. The rings are slipped over a combatant's fingers with the bumper pressed into the palm of the hand. When a punch is thrown, the brass knuckles take the majority of the impact impulse, transferring much of the punch's kinetic energy to the target by way of the harder, smaller impacting surface of the metal knuckles. This drastically increases the likelihood of serious tissue disruption and bone damage.
Few battles in Fallout Tactics lend themselves to unarmed close combat, as most enemies are well-equipped with firepower that can shred melee attackers before range can be closed. Yet, raiders, rioters, and other relatively weak opponents still use brass knuckles from time to time. While equipping squad members with brass knuckles is generally foolhardy and wasteful of carry limit weight, a reasonable profit can be made by collecting brass knuckles from defeated enemies and reselling them at a nearby Brotherhood bunker.
If you tag the unarmed skill, you'll start with a set.
