Last month Square-Enix trademarked something called ‘Deadman’s Cross‘. Maybe this is nothing more than a mobile or a browser game, but S-E is always capable of surprise.
This Deadman’s Cross is more likely a sequel to “Guardian Cross“, a smart phone game for iOS where the player captures creatures to form a deck of cards that they use to battle other players. The game was released on September 2012.
Thanks, NeoGaf.
