Frame Gride is a mech-based one-on-one fighting game played from a behind, over-the-shoulder view. It also contains missions and RPG elements that link the fights together. Attacks are based on both weapons and hack-and-slash swordplay. The mech can also strafe, jump and fly for a short while.

The rebellion of Margrave Zort, which began with the death of Emperor Regilio, engulfed an entire empire into a flaming epic war. Five armor giant electors have already been brutally defeated. Archbishop Mirange, the last remaining elector grants the title of knight to a young man. This young man is entrusted with hope as he must defeat the rebel army by piloting the armor giant "Frame Gride" utilizing an ancient power that has been passed down from ancient times.
