The series is notable for its cast of characters based on well-known fictional monsters, and introduced many of the concepts used in later Capcom fighting games, including the use of sixteen color animation sprites later employed in Street Fighter Alpha and a few of the Versus games. In recent years, Udon Entertainment has released an English translation of the Japanese Vampire: Graphic File artbook, a Darkstalkers Tribute book and Darkstalkers: Official Complete Works.
