Disabled: Not currently available
Brass Knuckles is currently disabled from the game. Assets for this exist within the game files, but will not be encountered through normal gameplay.
The Brass Knuckles's standard hits have a base power of 2.4 and a 0.3-second delay before another punch can be thrown.
If Brass Knuckles are used in both hands at once, a three-step combo and the Power Punch finisher become available to use. To advance through the combo, each punch must be followed within 0.5 seconds by another punch with the same hand. Once the combo is completed, the last punch of the combo must be followed within 0.5 seconds by another punch with the same hand to perform the finisher. Alternating hands (alternating left mouse and right mouse) will not cause a finisher to occur thus allowing a player to pummel enemies with regular attacks and execute a finisher when they wish.
The finisher, Power Punch, is a more powerful version of the standard punch. It has a base power of 6, and performing it incurs a 0.2-second delay before another punch can be thrown with either hand.
There is currently no way to obtain them in-game without using commands or external editors.
