The weapon is like the Buzzer melee weapon from the Golden Grin Casino DLC in that it shocks enemies on contact akin to players being electrocuted by a Taser. However, it has a 2 seconds-faster charge time and a slower initial swing but faster subsequent swings, making it more useful for repeatedly tasing an enemy or tasing multiple enemies. Additionally, also unlike the Buzzer, the Electrical Brass Knuckles unlocks much earlier and is not tied to a paid DLC.
Charging the Electrical Brass Knuckles has no effect on damage.
Once an enemy has been hit by the Electrical Brass Knuckles, it will be stunned for up to 3.2, 3.4, 3.7 or 3.9 seconds each. All of these stun durations have an equal chance (25%) of occurring when using the Electrical Brass Knuckles.
After approximately one second of charging, the Electrical Brass Knuckles make the same telltale electronic whine as the taser used by a regular Taser despite the weapon not having external speakers to emit this noise from.
Like players, shocked enemies will fire their weapons uncontrollably. During this stage, their weapons will not harm players in any manner.
It remains unclear how the Electrical Brass Knuckles transmit their stunning shock into an enemy's body as the contact points are merely power plugs that can't possibly pierce through clothing to reach the vulnerable flesh beneath. Granted enemies with less clothing such as MPD officers or security guards are more vulnerable due to their lack of protection, the Electrical Brass Knuckles' effect on more armored targets remain baffling.
Tasing a dominated enemy will cause him to repeat the surrendering animation after the stun wears off.
If one were to modify the Electrical Brass Knuckles' range value, they would find that SWAT Van Turrets are not affected by the knuckles.
Despite the inventory preview and store icon only showing one brass knuckle, the actual weapon has the player wielding two, similar to the Specialist Knives and Okinawan Style Kunai.
