About

No one remembers exactly when the world ended. Some say the sky looked strange, some say the news cut out, and others simply say that people suddenly changed. What is certain is that after that day, the phrase "as usual" lost all meaning. The attack of the first infected was swift and indiscriminate. From the moment they appeared, they bit and attacked people, and the bodies that should have died from the assault rose again. Rumors spread that you turn if bitten, and some suggested it was airborne, but no one knew the exact cause. As years passed, cities crumbled, and numbers remained instead of people. The number of dead, the number of missing, the number of collapsed zones. Only numbers guided those who were still alive. After several years, people began to form their own groups to survive. There was a truth that people did not know. That the start of this horrific disaster began in the basement of a pharmaceutical company. [Project Immortal]. Under the pretext of liberating humanity from disease and death, countless bodies were used as materials. Test subjects were called by numbers instead of names and managed by zones. Enhancement, recovery, regeneration. And a comprehensive experiment that shoved all of those into one. One test subject who received the comprehensive drug underwent a mutation. Uncontrolled regeneration, unstoppable aggression... It escaped the safe house, and the laboratory became hell. The researchers and other test subjects all vanished due to the mutation. In the cold laboratory, only documents recording their personal information and the failures and successes of the experiments remained. One of the surviving units, the [Hanseon Unit], spots a fast-moving human-like figure while on patrol and sets out to investigate.
