Defender Hyperswarm

The aliens known as the Manti have been destroyed by Defender pilot Mei
Kyoto when she helped the AI called Memory crash the moon into
Manti-occupied Earth. The remnants of humanity that live on the Solar
Colonies have been saved, but at the cost of their homeworld. Several
years have passed, and Kyoto has become a controversial figure. While
some view her as a hero, others demonize her as the destroyer of Earth.
Kyoto would like nothing better than to be an anonymous rookie pilot
again, but without the Manti threat to keep the Solar Colonies unified,
friction has developed between the human outposts.

Detroit Adams—now a general and head of the Galactic Stargate
Authority—has convinced Kyoto to use her celebrity status as a goodwill
ambassador to the Colonies, in the hope of keeping them unified… or at
least prevent open hostilities from breaking out….

Spun off from characters and events in the arcade classic, Defender:
Hyperswarm tells the space-combat story of a military unit as they fight
to defend their solar system and save the human race from alien
invasion.
