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


The sonic emitter - robo-scorpion is an Energy Weapons pistol with bonus damage against robots and power armor wearers, as well as a unique "critical strike explosion" effect. The projectile fired from this modulation travels noticeably slower than other modulations and it uses 3 energy cells per shot as opposed to 1 or 2 with the other variations. This sonic emitter modulation has a yellow oscilloscope. It also has a slight firing delay.

As a one-handed Energy Weapon, the sonic emitter - robo-scorpion is affected by The Professional perk, and counts as an improved holdout weapon.

When scoring a Critical Hit, a large explosion occurs.


The sonic emitter - robo-scorpion can fire a total of about 495 times using standard cells, the equivalent of 62 reloads, from full condition before breaking.

  • As with all sonic emitter modulations, it is necessary to install Blind Diode Jefferson's personality chip before this remodulation can be applied to the sonic emitter.
  • All cyberdogs are affected by the additional EMP damage done by this weapon.
