Both Freedom Wars and Soul Sacrifice: Delta servers will shut down on December 24. They were both PlayStation Vita exclusive titles developed by Japan Studio for the handheld system.
PlayStation Japan broke the news for both games on their respective pages on November 19. Freedom Wars and Soul Sacrifice: Delta were released on PlayStation Vita back in 2014, and the final message in the termination announcement was, “We would like to thank all of our players for enjoying the network play of this game.”
Right now, only PlayStation Japan has announced the server closures, so it’s unclear whether they will also extend to other regions as well. However, it wouldn’t be surprising if an official confirmation came soon.
