Originally announced for the PlayStation Portable, God Eater 2 will also appear on the PlayStation Vita, and both versions will be released and sold side by side in Japan next year.
The PlayStation Vita version will have “super gorgeous graphics,” meaning it will be in higher resolution and have better textures etc. The controls will of course be made to fit with the Vita’s control layout, and there will multiplayer with the ability to transfer data from the PlayStation Portable version. No plans for a localization have been announced.
