Guardic Gaiden (Japan)

About

In The Guardian Legend, the player controls the gynoid guardian of Earth, a "highly sophisticated aerobot transformer".[note 3] The player's mission is to infiltrate Naju, a large planet-like object which aliens sent hurtling towards the Earth.[note 4] While inside, the player must activate ten safety devices in order to initialize Naju's self-destruct mechanism and destroy the alien world before it reaches Earth. Five hostile tribes of alien lifeforms are vying for control of territories within Naju,[10] and the player needs to fight through them to successfully activate the switches and escape.[1]: 3, 6
