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.
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.
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。
