From the introduction:
Rise up dead man, your kind is needed now Hunter. Savage, nightmarish monsters roam the Louisiana swamps, and you are part of a group of rugged bounty hunters bound to rid the world of their ghastly presence. Banish these creatures from our world, and you will be paid generously—and given the chance to buy more gruesome and powerful weapons.
You will find yourself employed by an organization that sends you to perform the tasks mentioned above. You’ll start in a village close to your first mission. The organizations HQ doubles as a bar and you’ll probably spend most of your time here, drinking and conversing with your fellow Hunters. But now and then you’ll pick up your weapon, take a friend and venture out into that dark swamp to face the horrors that lurk there. Such is your destiny, such is your duty and such is the way you will spend the next ten years of your life.
