Muteguns are another breakthrough technology released by Circle of Fire Corporation. These devices allow its user to essentially "mute" the victim so that they will not hear them. The gun is actually double directed - both at the victim and the user. The devices sits in standby, listening to the surrounding activity. The gun is actually just a glorified imaging sensor, used to instruct the gun which person to mute. The mutegun then neurally manipulates the user's auditory system, making them subconsciously ignore that whom was fired on. The effect wears off over time.

In February of 2015, Mutegun announced they had officially sold over 1 million muteguns.
