Sonic Emitter (weapon)

The sonic emitter pistol is a weapon in the Fallout: New Vegas add-on Old World Blues.

Characteristics
Being grey in color and having four blue diodes as well as a blue oscilloscope on the rear, it fires a ring of blue energy towards its targets. It is said to have the ability to disable shields, unlock new areas and has the merit of being upgradeable and is given to you fairly early in the game. It also looks somewhat like the Pulse Gun Found in Vault 34
