Humans vs. Night Walkers
Millions of people go missing in the world every year. Where? I don't know where, but sometimes they come back. Lucky ones become dead. Less lucky ones knock at the door of their family home with a sinister smile. They were called Night Walkers.
In this crisis, the US American Investment Board secretly established a special forces unit and assigned a secret mission to kill the night walkers.
The night when it began to rain, which dulls the senses of the night walkers. We bet everything on this night and finish everything by the morning. A war that humanity cannot afford to lose begins quietly.
In the midst of the time limit of the night before the dawn, the protagonists scramble to carry out operations and the problems that occur one after another. What is the truth that you see?
A story full of fear, thrill and surprise awaits the player!
