"...We all deserve to go to hell."
About
You are a perfect lifeform, one of the few successful Flawless specimens. As you live your life as a test subject, Guest will...
What are the Flawless? Humans modified through special drugs and repeated experimentation who know neither disease nor hunger. They possess strength far beyond that of ordinary humans. They are also incredibly durable. A special device is attached to the choker around their neck; if a Flawless disobeys or attempts to escape, an electric shock is delivered. The choker also contains a GPS tracker. During experimentation, they are subjected to a memory-erasing device, causing them to forget their lives as humans. Their appearance is largely indistinguishable from humans.
