From the introduction:
Welcome to the year 2003. We live in a parallel world to that of your own, and it is a much darker place. Shadows are darker, buildings rise to the skies, monsters stalk people, and the place is paranoid and grim.
In the dark alley something moves. The predators of the night, vampires, werewolves and other supernatural creatures stalk the human population and each other and expand their grip over the human population.
But now it is time to strike back. An unofficial and secret organization has started a war against all unnatural creatures with one simple goal: total extermination.
Hunters presents a developed dark science fantasy setting adapted to the RIP rules system.
