In the last hours Konami has made available on
Facebook Castlevania: Lords of Shadow Challenge, a game that will let users unlock exclusive content related to the expected fantasy action game. It appears that we have to choose Challenge by swearing allegiance to the Brotherhood of Light Divine Mask or the Mask of the Demon Lords of Shadow, fighting alongside or against our friends in a virtual arena, gaining experience points and expanding our Army.
As a reward we can unlock screens, videos and special items for Castlevania: Lords of Shadow, expected in stores in two days.
