Desert Falcon is an obscure isometric shooter with an Egyptian theme, released exclusively for the Atari 7800 in 1987.
You play as a falcon, flying diagonally over the landscape, shooting stuff as you go, in a way similar to that seen in Sega‘s classic coin-op, Zaxxon.
This 1992 sequel to the arcade classic Terra Cresta is a PC Engine exclusive – it did not appear in arcades first.
It’s more of a remake than a sequel, but is incredibly varied and a more than worthy successor to Terra Cresta. As far as mainstream ‘Bullet Hell’ shooters go there are few better.
