Six months have passed since the Battle of Demeter. The Militia has turned the tide of the fifteen year old war- people (like Marcus Graves) turned from the IMC to the Militia cause, they've taken out half of robotics facilities, and have conducted successful raids like "Operation Grizzly" which not only gave them a shipyard but a fleet of prototype carriers(the 1st Grizzly Fleet).
Nobody knows when or how the war will end. But one thing is for certain, this war will change the Frontier forever.
