Is this even out for xbox 360? I have been hearing that it was released last month and i didnt hear anything about it so i checked xbox live but i dont see anything that will let anything in the castlevania: lords of shadow section
^ I just checked 30 seconds ago from this post. It's there.
So from the Dashboard, I went to the Game Marketplace then I went to the Titles A-Z, then C, then Castlevania LoS then Right Bumper to the Extras tab then I see about 5 items of stuff, then I scrolled down to See All Extras There should be 14/14 items, Resurrection is one of those.
If it's not showing up for you, you might want to contact xbox support.
