Following the freshly released teaser trailer, some new details have leaked out about the upcoming Sony-published PlayStation Vita title Soul Sacrifice. Japanese blog Andriasang has once again dug up some goodies from print publication Famitsu that confirm the long-standing rumours that Mega Man creator -- and outspoken critic of the state of Japanese game development -- Keiji Inafune is working on the project with Harvest Moon and Rune Factory developer Marvelous AQL, along with Yasunori Mitsuda of Chrono Trigger and Xenoblade fame and Resident Evil 5's Wataru Hokoyama.

Details are a bit sketchy, perhaps due to translation difficulties, so we're still not exactly sure what type of game it is (the teaser trailer suggests action), but the many European mythology references indicate a dark fantasy theme and some of the key mechanics sound rather messed up.

The game's protagonist is reportedly a practitioner of a dark brand of magic called Sacrifice magic and the game's title refers to the way that corporeal sacrifices must be made in order to use it. The examples given are weapons that require the sacrifices of fingers, eyeballs and nerves to summon attacks from your body. An attack named Excalibur is supposedly executed by tearing your spinal cord through from your mouth to use as a sword.

Monsters in the game are said to be disfigured humans that have had too much magic used on them and notable beasts include Cerberus, Minotaurs and Harpies.
