Hey Daniel, the GM's character guidelines are stuff are on the application page I linked. The setting is modern day, mainly US but we've ventured across the globe. Slight alternate history (Schwarzenegger become President) but nothing too major. In Hunter, you play as an awakened human who's come to realize there are nasty things that go bump in the night. Our job is to hunt them down and redeem or destroy them, basically. As far as what kind of character, you are pretty much free to come up with any typical human background. Your character would basically just need to be 18+ and have a sane background. The GM isn't looking for characters who are ex-special op terrorist hunting assassins, for example. Police officer, sure. But you're supposed to be a pretty average human. He can help you make your actual character sheet and pick your skills, etc. if your background works.
