Did Monster Hunter Frontier G Offer Xbox Live Codes?

No, Monster Hunter Frontier G never distributed Xbox Live codes. The title was a PC-exclusive release in Japan.

Confusion may stem from Monster Hunter Online (a separate PC-only title), which occasionally included Xbox Live subscription codes as limited-time promotional bonuses. Those promotions ended years ago, and neither game's servers are currently active.

Therefore, obtaining Xbox Live codes through either Monster Hunter Frontier G or Monster Hunter Online is no longer possible.
