HalluciGen , Inc . ( company ) HalluciGen , Incorporated was a pre - War company based in Boston that researched and developed " non - lethal " biochemical technology for use by the United States Armed Forces and police forces across the country for riot and crowd control , in the wake of food riots and other forms of civil unrest . Background . Releasing HalluciGen Gas in 2055 , the company tested other innovations at their building , with Eric Rice as the president and CEO , and Damien Hansen as the head researcher . Notices were placed around Boston asking people to become test subjects for HalluciGen products for cash . By 2077 , Colonel Thomas Nelson acted as an ambassador between the armed forces and HalluciGen . By 2077 , many projects were still being heavily tested , with setbacks , failures , and sometimes sheer incompetence on some researchers ' part being rife . Products . Dispersant . Dispersant was intended to stop riots and clearing areas of civilians . One test subject failed to recover from treatment after being exposed to Dispersant , and ran screaming from the sight of his own child in the waiting room . Two days later , he was apprehended and institutionalized . The then project lead was later replaced by a woman named Karyn . HalluciGen Gas . Created in 2055 with the goal of riot pacification , its side effects were unpredictable sensory experiences , and high dosages could result in catastrophic adrenal failure , leading to hallucinations , erratic behavior , and increased aggression . Throughout testing , new formulations were synthesized , however the gas still caused traumatic adrenal gland rupture and frenzy . One subject who survived testing began to acclimate before he was beaten to death by four other frenzied subjects , and another died of heart failure . Another issue the researchers encountered was that when the gas was deployed at the concentrations required for wide - area dispersal , massive adrenaline surges occurred in the subjects . The researchers believed the gas would have made a good grenade or artillery shell , and that if HalluciGen marketing represented the gas as a military - grade chemical weapon , there would have been no need for further testing . A known way of deploying the gas was through Type II fragmentation grenades . Some subjects were injured by the grenades . The gas itself was kept inside of gas canisters . Irradicator . The Irradicator was envisioned to be a hand - held field decontaminator , with the goal of field decontamination . During testing , subjects received lethal doses of radiation , with one receiving 5100 rads , resulting in their skin disintegrating . Small amounts of residual radiation could persist in affected areas after use , therefore requiring the panels and insulation to be replaced . The research team were planning to change the dosage pending safety evaluations . The possibility of reclassifying the Irradicator for lethal weapons research was also raised . The power supply for the Irradicator required further development , which at one point weighed 2 tons , which was unsuitable for field deployment . It could also neutralize large amounts of biochemical contaminants . InvisiWave . The InvisiWave was the result of five mirrors , two hacked Stealth Boys , and a trap door . Supposedly , it was capable of making subjects inaudible and / or intangible , with the effects possibly capable of being permanent . The third test was deemed a success , impressing a US Admiral overseeing the test . The company ' s sales department ordered two - hundred units to be manufactured by December 2077 . Suppressor . The Suppressor was created to paralyze even armored targets , and provided target suppression through electrical discharges . Side effects included the partial and / or complete paralysis of the user , bystanders , small animals , and / or large animals . Test subjects became incapacitated . The researchers deemed that the paralysis appeared to be permanent . The highest - paid researcher in the company , the Suppressor ' s project lead was also the lead engineer for Implied Hypnotics , Inc . ' s Mesmetron weapon , and even reverse - engineered some of their own prototypes during development of the Suppressor . Appearances . The HalluciGen building and HalluciGen products appear in " Fallout 4 " .
