SCE Japan is one of Sony’s many internal studios, which tends to help out with other studios in the development of games exclusively for PlayStation platforms. Three of those games, only one of which has already been released in Japan, have now been officially confirmed for a US release.
The one game that has already released in Japan is Soul Sacrifice Delta, the expansion of the already released Soul Sacrifice. The other two that still have to come are Freedom Wars and Oreshika: Tainted Bloodlines. Soul Sacrifice Delta has been given a US release date of May 13, while the other two were not given one quite yet. Stay tuned for more information on those releases dates as they are announced in the future.
