This Whole Place Feels Like it Wants Me Dead

It's the year 2054. Humanity has almost gone extinct from a virus originating from Arizona with no real explanation as to why or how it started. At least, that's what the public was told.
In 2010, a company known as Terra Corporation was created. It was an organization dedicated to improving the immune system of humans and strengthening the current vaccines. What they managed to do instead was enhance and strengthen a person beyond their natural capabilities. By 2036, they started to search for and experiment on different resources and people that could be used to enhance the human body and create the perfect human. They managed to create superhuman beings and even figured out the first stages of cloning. It was a shame that they would drop all means of safety and regulations for science. Their ignorance for this resulted in a catastrophic event known as the LC Breach.
