Mesmetron (Fallout: The Roleplaying Game)

The Mesmetron is a weapon $$

Background
Developed by Implied Hypnotics, Inc. before the War, the Mesmetron is an experimental "non-lethal subjugation device" provided to the United States military for them to assist in experimental trials. It operates by sending a series of waves that the brain attempts to decode, but because the synapses are being overwhelmed by the neural static, the brain becomes confused and switches off important higher-level mental functions and voluntary motor control, leaving the target extremely susceptible to suggestion.

While still in its testing phase, the weapon was found to have the potential to trigger two undesirable side-effects: extremely increased aggression or a "resonant brain wave feedback loop" which resulted in spontaneous cranial eruption. Several devices were attached to Robobrains to aid in the interrogation processes. (Officially noting the 10-15% casualties due to spontaneous cranial eruption.)

Gameplay
The Mesmetron can accept several mods from the Core Rulebook, including the Beta Wave Tuner, Sharpshooter's Grip and the Reflex Sight.
