Square-Enix has shown off a pretty lengthy and detailed trailer for their upcoming PSP shooter The 3rd Birthday. As you probably already know, this title is an extention of the Parasite Eve universe, carrying over many things, including the main character, Aya Brea. In the trailer you’ll get an idea of the story you’ll be playing through and you’ll see some very nicely rendered cut scenes, as well as a few pieces of actual game play. This is shaping up to be a great-looking title that makes use of the PSP to a pretty full extent. Hit the jump to check out the trailer and let us know what you think in the comments!
