A sequel for the PlayStation Vita, titled Soul Sacrifice Delta, was announced during TGS 2013. The core mechanic of the game is the ability to sacrifice parts of the character's body or items to create devastating attacks. These sacrifices will be permanently marked on the player character's body, meaning that they are not an infinite resource that can be tapped into.
