[8] Gungriffon received highly positive reviews, with critics hailing it as one of the best mech-based video games to date.
"[9] Rad Automatic of Sega Saturn Magazine called Gungriffon "one of the best giant robot games ever", citing the polished graphics and the fact that missions are widely varied not just in the usual factors of terrain and difficulty, but even in elements such as tactical concept and lighting.
[13] Maximum's Rich Leadbetter praised the "very well pitched" difficulty, the impressive polygon models, and the variety of visuals.
He criticized the lack of randomization and the fact that players do not need to start the entire game over when they fail a mission, but gave it an overall very positive assessment, calling it "what Krazy Ivan on PlayStation should have been".
[12] GamePro likewise said that Gungriffon "makes Krazy Ivan and Ghen War look and feel like rusted heaps of scrap iron."
