Atlus shared a bunch of screenshots for their expanded port of Persona 2: Innocent Sin. Before we get to those check out the box art for the Japanese version. The cover art shows Tatsuya and Maya with their personas, Apollo and Artemis rising to the top.
Persona 2: Innocent Sin has a union skill system where characters can combine their powers for stronger attacks. Maya and Tatsuya, for example, can summon King Frost. Up to five characters can participate in a skill union. If Tatsuya, Eikichi, Lisa, Maya, and Yukino team up they can summon a Shikigami. Union skills have cut-in graphics, a new feature for the PSP version.
Atlus also added an emotion meter similar to the one seen in Shin Megami Tensei: Persona for PSP. This is designed to help players during demon negations.
After a slight delay, Persona 2: Innocent Sin is on track for April 14 in Japan.
