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.[1] 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,[1] leaving the target extremely susceptible to suggestion.[2] 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.[1] Despite the prototypical nature of the device, several were attached to robobrains to add in interrogation processes. (Officially noting the 10-15% casualties due to spontaneous cranial eruption.)[3]
