The wait for The 3rd Birthday won’t be too long. Japan gets the PSP game first on December 22. Square Enix has The 3rd Birthday slated for Q1 2011 in North America. In plain English, that’s sometime between January 1 and March 31 of next year.
The 3rd Birthday, if you haven’t been following it, is a departure from the Parasite Eve games. It still stars Aya Brea and is set in New York. However, it’s a shooter where Aya uses the Overdive system to control other comrades on the battlefield by swapping their body and mind with hers.
