A new entry in the Parasite Eve franchise has been long coming. The 3rd Birthday -- the first official sequel in the franchise since 1999 -- will be available in Japan at the very end of this year, on December 22nd. A US release is likely to follow some time in 2011. The third-person shooter arrives exclusively for PSP, joining the now-officially-announced Kingdom Hearts: Birth by Sleep Final Mix and Dissidia: Duodecim.

With so many high-profile Square Enix releases coming to PSP so close to each other, the company announced that there will be some kind of cross-promotional DLC across all three games. Specifics weren't mentioned, but you'll be able to unlock special costumes by owning multiple games.
