The 3rd Birthday is a PSP game by Square Enix. It was originally released for Japanese mobile phones. It is a sequel to Parasite Eve with Aya fighting a monster infestation in New York.
This game stands out from other PSP games because of its visuals which look great on the PSP. And it reminds me of the original games.
A unique feature in the game is the ability to see Aya’s clothes get ruined and see her skin get bloodied. This happens when she takes damage. At the moment I am not sure if this makes the game more or less realistic. Either way it makes the game different and visual interesting and you can see her bum in more detail, after all your going to be seeing her back a lot.
