Trooper 2: Alien Justice

Trooper 2: Alien Justice is about a war between humanity and the Ashtar Commandos, a dangerous alien species that has monitored Earth for centuries. After NASA launches its first spacecraft, the Ashtar reach Earth to investigate and manipulate humanity, looking for its weaknesses. They plan to destroy humanity when it enters space, and begin their attack as conflict and violence increase on Earth.

The conflict

The Arcturians have defended Earth from alien attacks for centuries and are also monitoring the Ashtar. They send a ship carrying cyborgs to defend humanity, but the Ashtar intercept it and it crashes near a city on Earth. The Arcturians are far away and believe their cyborg ship will destroy the Ashtar; they do not know it has been shot down. The story leaves open the possibility that a cyborg survived the crash.
