When the trailer video titled "All Who Follow You" for the upcoming "Batman: Arkham Knight" was shown, observers noted that in one scene, the Caped Crusader seemed to be holding a gun, and hardcore Batman fans are asking if the Dark Knight is now deviating from his earlier premise of non-killing. 

The weapon Batman is using in the game is indeed a gun, but one that doesn't kill at all. Officially called the Disruptor, the device jams the weapons of enemies, and is one of the mostly non-lethal equipment players will have access to in the upcoming "Batman: Arkham Knight" game. 

According to the official WB Games forum, the Disruptor works both as a sniping rifle and as a close-range combat support. Limited to only three charges per engagement, the weapon works as a jamming device for weapons, rendering them ineffective; if two charges are used, makes weapons explode; laying a trap that shocks enemies who try to use weapon crates; and finally, to tag and track vehicles when in pursuit using the Batmobile.

As a tactical equipment, the Disruptor has a long range scope that players can use to scout and check out a situation before entering an engagement.

Aside from the stock cartridges, the Disruptor can also be improved, increasing the number of charges and usage per engagement. In its highest upgrade, the Disruptor can even be used on drones. By upgrading the weapon, Batman can hack the turret systems of in-game drone tanks. This will make the tanks a moving pillbox, which would explode when the drones would try to track and engage the player.

"Batman: Arkham Knight" is set to be released on June 23 for the Xbox One, Playstation 4, and PC and is the last title in a trilogy.
