"Soul Sacrifice," and its expansion "Soul Sacrifice Delta," is an action roleplaying series in a similar vein as "Monster Hunter." Players embark on a quest to defeat an evil sorcerer who uses human sacrifices to stay immortal. A central game mechanic allows players to sacrifice items, teammates or even themselves to cast powerful magic.
"Soul Sacrifice" featured both online and local multiplayer, and players could also make use of a special Vita function to give each other items if they were near another "Soul Sacrifice" player.
Sadly, with the Vita no longer being produced, it's unlikely that the Sony-exclusive series will make the jump to PS4.
