N.O.V.A. – Near Orbit Vanguard Alliance

At an indeterminate point in the future, Earth is rendered uninhabitable by humans and animals by unknown means. Therefore, humans built satellites in space. But in order to protect themselves from Xenos, they created an alliance called N.O.V.A, or “Near Orbit Vanguard Alliance”. Kal Wardin, a N.O.V.A Commander, is enjoying his drink, when 2 soldiers come up to him and knock him out. Kal wakes up in a training area, tries to head to his ship, but is attacked by Xenos. After, he goes to a colonial frigate, which has gone quiet for some time, for unknown reasons. Kal crashes his ship inside the air lock. He is attacked by Raiders. Kal is then told to self-destruct the frigate. He explodes it, and lands back on earth. He meets up later with possible survivors from the frigate. He goes to the planet of the Xenos, but Yelena is deleted. He pushes through and finds the judger. Kal kills it, but the whole planet possibly explodes.
