In the year 2991 AD, the Galactic Federal Government agreed to a full-scale disarmament treaty with the Andromeda nation and it looked like the galaxy would finally be at peace. However, just before the signing of the treaty, members of the military-industrial complex, who were opposed to the treaty, carried out a coup d'état to prevent this. Colonel Iritsa Renina, commander of the Beta Unit of the Galactic Federation, refused to help the coup and ordered the rebellion to be suppressed. The object of the game is that you, the Beta Unit ace pilot Ensign Rova Trotskyna, must destroy the federal facility that was occupied in the coup.
