Pushy is a unique version of the displacer glove. Instead of the usual silver plating, the forearm unit and knuckle plate emitter are dark gray. As with the regular displacer glove, Pushy causes a knockback effect on a successful hit, with a visual effect similar to that of a Gauss rifle. Pushy has the highest DPS of any unarmed weapon in the base game, but is ultimately outclassed by Industrial Hand with all DPS-aided perks added.
Despite having energy cells visible on itself, Pushy does not require ammo.
It has what looks like a speaker on the fist, which likely is how it "pushes" its enemies.
If the player has the Ranger Takedown Perk, in the third person view when performing the leg sweep, where the leg comes into contact with the target, it still creates the same wave of energy even though the fist isn't technically used.
Sometime before release, displacer gloves, as well as many other fists, were supposed to use energy cells as ammunition, but it wasn't supported by the game engine and there was not enough time for implementation.
