Galactic Troopers

For three thousand years, the Terran Empire has ruled the Galactic Expanse with an iron fist, conquering any alien civilisation who dared to oppose the might of their new human masters. Their grip is about to be shaken apart when an unknown invasion force starts to strip whole planetary populations. Now humans and aliens must find a way to work together to prevent the Empire and the invaders turning the Galactic Expanse into a graveyard.
