The year is 2220. Every night, the world plunges into terror as demonic beasts emerge from the shadows, hunting humans to absorb their intelligence. Survivors are forced into fortified cities where advanced technology is their only hope. These creatures are traced back to a mysterious portal leading to a nightmarish planet called Comeion.
With years of endurance and ingenuity, humanity has developed weapons capable of piercing their tough hides. However, a special task force is assembled to close the portal once and for all.
