The game is an action role-playing game described by Square Enix as a "cinematic action RPG". Director Hajime Tabata noted that the gameplay and plot are intertwined due to a newly introduced ability called "Overdive," an ability that lets the player switch bodies with one of their team members, allowing them to control friendly NPCs.
My input:
Such a game is I think only available on PSP and I have played it. I could say that if you like mindless shooting at everything that moves, this game is for you. You get a variety of guns and practically unlimited number of bullets. The game itself has horror elements that are actually a bit scary, the story is great, game play is long.
All in all the game is very good... didn't expect it to be this good from an asian game developer team, because it seems all they produce is anime bullshit.
