The year is 2267, and humanity is at war. Four years ago, humans encountered an alien species called the Chitiri. Both species initiated first contact in the hopes of learning more about their neighbors and developing a peaceful relationship.

With extinction on the line, there is only one choice; defeat the other species so badly they can never fight again.
Domain is a semi-hard science fiction story set in the center of a brutal interstellar conflict. It focuses on the men and women who are on the front lines, piloting military warships and sitting in trenches as they fight in a domain where newton's first law reigns supreme.
