Grim Pulse: The First Blood is an ARPG that follows Aelthar, an ancient vampire who awakens 9,743 years after being sent to his Eternal Slumber within a modern city locked in a dreamlike state of blood, control, and forgotten history. As he dismantles vampire Covens embedded within towering skyscrapers, Aelthar uncovers a hidden hierarchy known as the Vampire Council, and the truth that his resurrection was never accidental. Through combat, exploration/eavesdropping, and fractured memories, he must confront his past, a tragic love named Lisette, and the burden of the First Blood itself.
