Monster Hunter Frontier G was originally launched as an update for the Xbox 360 and PC versions of Monster Hunter Frontier Online, then later hit the PlayStation 3 and Wii U as a standalone retail release. A PlayStation Vita port is also in the works. The GG update is set to arrive next year for all supported platforms.
While many entries in the core Monster Hunter series have been released stateside, the online-only Frontier games are exclusive to Japan. A North American release for Monster Hunter Frontier GG has not been announced.
