Things were left pretty open at the end of Castlevania: Lords of Shadow so it's inevitable that Gabriel Belmont is being brought back to deal with some unfinished business. Two DLC packs launching in February and April 2011 see Gabriel deal with one more problem at the castle of the vampire dark lord and bring some closure to the story.
'Reverie' sees Gabriel heading back to the dark lord's castle to help out Laura, a former servant to the vampire queen Carmilla. Apparently Carmilla had kept some "unruly evil" in check but now that she's dead, this evil is now running rampant so it's up to Gabriel to destroy it.
'Resurrection' takes place after the ending to give players some insight into Gabriel's ultimate destiny. There's no rest for Gabriel here either as he must fight at his peak to take on a "notorious enemy".
