Hunter: The Reckoning

One year before the events of the game, the execution of convicted serial killer Nathaniel Arkady at Ashcroft Penitentiary caused those who have died by hand of the prison warden rise up in revenge. The four people who were present at Arkady's execution witnessed the uprising of the supernatural evil, and all four received a message in their minds to act against the vast supernatural force that threatened the entire population of Ashcroft.
