A struggle between light and dark, from 300 years back, is about to ensue. The parties involved are Albert and Michael, the two vampire hunters representing light, and the vampires representing dark. The story takes place in an alternate version of the year 2006, when progress looks stuck in the 19th century.
Albert and Michael rescue a 12- year old girl named Caroline who witnessed a couple of villagers held hostage by the vampire Sarcoma. After rescuing the villagers and Caroline, the vampire hunters proceed into the castle to destroy the remaining forces of dark.
From the Wikipedia page.
Although the forces of evil reveal that they created Albert and Michael and used them to kill themselves, but they became afraid of death and tried to stop them. It is important to note that the hunters are in fact Dhampyrs (half-vampires), due to their glowing eyes and sunglasses. The outcome is a pyrrhic victory for the forces of good as the forces of evil are stopped but at the cost of Albert's and Michael's lives.
Albert and Michael are half vapmires created by Count Augustine. This results in Albert and Michael having special abilities like; superhuman strength, a leaping ability and vampiric traits such as golden-glowing eyes. They are determined to wipeout vampires for good.
Caroline is a 12-year old girl whose traumatic experiences of her childhood "ages" her before her years. She is the only survivor of a vampire onslaught. Albert and Michael saved her from the onslaught and continue to look after her throughout the game.
