An archeological expedition has mysteriously disappeared during an exploration of the risen island of R'lyeh. You are a member of a rescue team sent to aid them. But as you investigate the site, you encounter something terrible that seeks to destroy your team from within... 

You'll need intuition, nerves of steel, and clever acting if you're going to survive and win the game. So block the doors, quarantine a suspect, reveal your identity to your ''allies'', grab a flamethrower or run away... but be careful because ''The Thing'' might be closer than you think...
