Pew Pew

 is a unique weapon in Fallout: New Vegas.

Background
Pew Pew belonged to Allen Marks, a man infamous for hunting people for Sunset Sarsaparilla star bottle caps in the Mojave Wasteland. He broke into the Sunset Sarsaparilla Headquarters prize vault, not knowing it was airtight, and was met with his demise.

Characteristics
Visually, the upper casing of the weapon has been colored red, and the focus adjustment knob on the rear of the gun has a Sunset Sarsaparilla bottle cap with a crudely drawn star attached by a screw. Underneath the bottle cap are the words "Had it coming" etched into the casing, along with eight hash marks. Additional hash marks also appear along both sides and the underside of the main body of the pistol.

On top of the main body is a wooden plate with what appears to be two capacitors attached by nails, strapped on by black tape and wired into the main body in series by a red and blue wire, hinting at its extra power output. It fires a distinctly orange beam, with the flare from the muzzle being more intense than a normal laser pistol.

does drastically more damage than the standard laser pistol, but at the cost of 5 energy cells per shot, resulting in only 2 shots before reloading. Furthermore, it is considered an improved holdout weapon, and can be concealed so long as your sneak skill is 50 or greater.

Variants

 * Laser pistol, standard variant found throughout the Mojave Wasteland.
 * Missing Laser Pistol, found only during the Pistol Packing unmarked quest.
 * Compliance Regulator, found only with the Honest Hearts add-on, it paralyzes a target on a critical hit.

Location
This weapon can be found inside the Sunset Sarsaparilla Headquarters after presenting at least 50 Sunset Sarsaparilla star bottle caps to Festus and beginning the quest A Valuable Lesson. The weapon is found next to the body of Allen Marks but is not in his inventory.

Behind the scenes

 * "Pew Pew" is a commonly used onomatopoeia representing the sound of a laser.
