Atlus brought us Shin Megami Tensei: Persona 3 three years ago. Maybe you forgot what the Dark Hour is now. Maybe you skipped it. Or maybe you can’t get enough Persona 3. (Apparently, Japan can’t.) If any of those profiles fit you watch this.
Atlus put together a video walkthrough that summarizes the story and explains how the game works.
This isn’t a direct port. Atlus revised the battle system to make it more like Persona 4. You can control allies now and they can take fatal blows for the main character. Shin Megami Tensei: Persona 3 Portable also has new costumes, part time jobs, spell cards to transfer abilities (think Shin Megami Tensei: Strange Journey’s sources), and of course a female protagonist.
