This is an energy weapon that fires in three-round bursts. It was made as part of an effort to expand the number of roles that energy weapons can fill, in this case the equivalent of a machine pistol.

Parts Used

I started with the legacy-content Alien Atomizer mesh from the Mothership Zeta DLC for Fallout 3 and removed everything except the barrel, which I then mated to the grip of That Gun, and added the bolt mechanism of the Silenced .22 Pistol.

Perks and Challenges

The following properties, perks and challenges apply to this weapon:

• Improved Holdout Weapon
• Plasma Spaz
• The Professional
• Curios and Relics
• Open to Experimentation

Procurement

This weapon must be purchased from Dr. Quarton, and cannot otherwise be obtained without console commands.

Dr. Quarton's Notes

The terminal entry in Dr. Quarton's laboratory notes the following:

Project #E-276-X - "Burst Pulser"

A relatively simple project, this, being an attempt to add select fire to the
weapon I recovered from Subject X. Only minor modifications required.
