There are over one hundred unlockable planes in Birds of Steel. Ranging from pre-WWII biplanes to the late war invention of the jet fighter to some really obscure Australian hardware. Each of these planes is special and unique with the same remarkable level of detail; they all feel, fly, and even sound different. This is the heart of Birds of Steel. In answer to our earlier question, this game is designed to appeal to lovers of WWII era war planes. It’s like Forza, and in that regard Birds of Steel comes through with flying colors.
