Intro. This place was an underground laboratory where they experimented on people in the 60s, no one knew about the atrocities they did, the façade of human experimentation was virus research and yes there were scientists who researched viruses and knew nothing about human experiments, but further down in the laboratories there were scientists who kept people locked in cages and experimented with them in atrocious ways, in the 80s an incident occurred, out of nowhere all the scientists disappeared and the laboratories remained abandoned or believed to be the humans who suffered from the scientists' experiments are still hidden in the depths You were one of the scientists who was involved in the human experiments but you never agreed with those experiments, resigning three before the incident occurred, It's been 10 years, but I brought you a letter a few days ago with a message
