 Even though the first mission against the Bydo Empire was an apparent success, the latest deep-space probes have revealed a secret Bydo base. It appears that the Empire has been in seclusion since it s headquarters were destroyed, stockpiling weapons and resources. Once more, the Earth is under threat of attack from the extra-terrestrial mutants and the world government needs you to fight back...again. The bio-mechanical aliens of the evil Bydo Empire are back, many of the bosses from the original R-Type are repeated (albeit in slightly different guises) and the distinctive pastel shades of the original are used again to create an immediately familiar feel.
