Releasing HalluciGen Gas in 2055, the company tested other innovations at their building, with总裁兼执行长艾瑞克·莱斯, and Damien Hansen as the head researcher. 为了测试自家产品，幻露生公司在波士頓招募实验人员。2077年上校托马斯·尼尔森 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.
原本这是要与镇压器配合使用驱散暴乱人群的，但是用于实验的对象虽然没死，出来看到自己的孩子之后，立即陷入疯狂，尖叫着逃走了，被抓住之后送进疗养院，负责这个项目的工程师当即被解雇 replaced by a woman named Karyn.
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. 参与幻露生气体实验的五名对象，有四个人的肾上腺严重破裂，仅有一人开始适应，但是这个人还被其它人活活打死了, 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. 不过营销部门准备把这个产品定位成军用级的化学武器，用大炮投放到敌方区域就可以扰乱敌人了。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.
An attempt was made to spread their product testing outside of their own facility by sending canisters of their gas, along with a full order estimate, to Vivian Garrahan of Garrahan Mining, in an attempt to assist with the mining protests in Appalachia.
消辐喷洒器原本是想做成“掌上型辐射消除器”，但是研发部居然做出了一个两吨重的家伙，并且会产生巨量的辐射，导致实验对象在测试仓房里接收了5100单位辐射，他們的皮肤都被分解了。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 致命武器 research was also raised. The power supply for the Irradicator required further development, It could also neutralize large amounts of biochemical contaminants.
隐形波是由五面镜子、两个被破解的隐形小子加上一个活板门营造的。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, 美国海军上校观看了隐形波的演示希望能运用到舰船上，該年底就要两百件。
的这个东西原本是用于通过放电镇压暴乱群众的，Side effects included the partial and/or complete paralysis of the user, bystanders, small animals, and/or large animals. 但是，被电击击中的人员全都永久性瘫痪了。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.
