About This Game

Dr. William, who is a slave to the desire for power, sends a research team consisting of Hannah Falkenhorst, Black Jack Kane, Grimroot, and Marco Rocio to the town of Golden Horn to obtain the Korion Jewel, which gives mystical powers to its owner. It doesn't take long for the research team, who are unaware of the powers of Korion, to realize that they are trapped in Goldenhorn. The guardian of the jewel with mystical powers has no intention of sending the team back alive.

In this exciting adventure where the roles of hunter and prey are reversed, join the team of bounty hunters and try to survive through cooperation, or direct the jewel guardian and defeat the bounty hunters.

To win this challenge, take on the role of good or evil, take control of your destiny, and survive no matter what!
