Maybe add it you are in a city , however it was abandon years ago because of " Vampire " sightings and you have been sent by the government to investigate this case , however you also have an objective to Survive the vampires I would think if a vampire was to kill you , you would wake up in some sort of area as a vampire maybe someone saves you in time these could be a checkpoint system in the game. Also if you want to add more of an adventure maybe add bosses!
