According to Konami's official Japanese site
, Castlevania: Harmony of Despair
will receive two new stages in January, each worth 320 Microsoft Points.
The levels, according to Google Translate, are called "Lord of the Flies" and "Too many, as one." The former is accompanied by a "coming soon" sign while the latter has the following screenshot:
"Too many, as one" is based off an underground stage from Castlevania: Symphony of the Night
, creating even more similarities between Harmony of Despair
and Symphony of Night
Konami's site does not state if the January 2011 release date is only for Japan or for folks all over. Additionally, there are no details on whether this DLC has any achievements.
