Gungriffon is a series of video games developed by Game Arts and designed by the late Takeshi Miyaji. Gungriffon and Gungriffon II originally appeared for the Sega Saturn console in 1996, with more recent appearances in Gungriffon Blaze for the PlayStation 2 and Gungriffon: Allied Strike for the Xbox. The Gungriffon games are focused on piloting mecha: large, usually bipedal military vehicles. This game series refers to these machines as Armored Walking Gun Systems (AWGS). With the exception of the High-MACS design, the mecha in this series have a distinctly realistic design philosophy, which is more apparent in the more recent installments.
