Natsume has at least two PSP games in the pipeline. In addition to Carnage Heart EXA, Natsume also picked up Mystic Chronicles from Kemco. Mystic Chronicles is a throwback to Super Nintendo RPGs with pixilated heroes and turn based battles. In this game you play as Lux, a boy adopted by a small village. Lux joins the Guardians Guild to protect his home, but Lux’s plans and destiny changes when he meets a young girl.
Each character in Mystic Chronicles has a changeable Guardian Beast as an ally. In battle, you select attacks for Lux and other characters while Guardian Beasts act on their own. Players can set the Guardian Beasts’ AI to be offensive, defensive or as a healer.
You may have seen Mystic Chronicles on Siliconera earlier. This PSP game is a port of an iOS RPG called Fantasy Chronicles. Natsume gave it a new localization since the main characters name is "Light" in the English release currently on iOS. Mystic Chronicles will be available for PSP this summer.
