Cthulhu: Why Is My Sanity in the Negatives?

In 2060, Cthulhu creatures known as the Dead Realm Civilization descended upon Blue Star. Within a year, countries around the world fell one after another, leaving only three safe havens on the entire planet. The apocalypse has arrived, and the old rules no longer apply. You must watch out not only for loathsome creatures lurking everywhere and strange gods looking down upon all things, but also for people hiding malicious intentions right beside you. My name is Chen Mo. I'm a combat officer in the Mechanical Alliance, serving in the Seventh Zone of the Asian Safe Haven. I sincerely advise you: if you want to survive in the safe haven, there's only one way. "Be ruthless enough!"
