For players who are still playing Castlevania: HoD, then this final piece of DLC sounds very enticing. The final level is called Getsu Fuma Den which according to wikipedia translates to "Legend of Getsu Fūma" or "The Legend of the Lunar Wind Demon." The game Getsu Fūma Den has never been released outside of Japan although it has been translated to English before. The final level is made up of vintage graphics heavily inspired by Getsu Fūma Den and includes Fuuma (from GFD) in the DLC. This is available now on XBLA for 320 Microsoft Points.
