Sequel (storywise, that is) to the 1994 Sega Genesis title "Castlevania Bloodlinea".
This game is the second to feature the "Morris Family", who have laid claim to the Belmont's Vampire Killer whip.
Some of Richter's sprites, animations and moves are actually unused sprites from Castlevania: Symphony of the Night, such as his jumping spin kick and crouching sweep kick.
By defeating 1,000 Old Axe Armors in the regular story, you can unlock a special version of the game in which you will play as an Old Axe Armor. This mode is the only special mode which does not give you a partner.
