The Trinity Wars

The swarm has been a fact of life for the past hundred or so years, especially after they managed to make planetfall. The subsequent evacuation was considered the only chance for humanity to survive as a species. We took to space like fish to water; it seemed to be in our DNA to explore the universe. Earth was quickly devoured while the escapees managed to reach Mars, the point of the first contact with the swarm, a planet that even they had left for greener pastures. We set up an outpost and began creating a colony, but the swarm was still in the back of our minds. They had our planet, and we wanted it back!
