Darkstalkers Resurrection

From the introduction:

You’ve probably heard this one before. The modern world, late 20th century. Humanity goes about it’s business as normal, living out their short little lives as best they can, all the while unaware of the truth of the world. Humanity is not alone on Earth, nor is Earth alone among worlds. They are the prey for dark forces beyond their understanding. These forces even have a name, given by those few humans in the know. The Darkstalkers.
