When Shawn Gallagher, second shift lead man at mining site A on Europa launches his bid for independence, little does he know that it will pit him against his little brother David. A Fleet Marine in the Federal Defense Forces. When Cyrus Bonelli, President of the Council of Economic Unions on Earth, hears of the rebellion on Europa he sends the federal main battle fleet to stop the rebellion. With rebels on Mars wrecking havoc,and the new deep space fleet heading out of the solar system to explore the galaxy, this rebellion on Europa couldn't have come at a worse time, but Cyrus has little choice. The federal fleet needs the Helium-3 and the colonies on Earth's moon as well as the colonies on Mars need the water ice that they mine on Europa, so Cyrus launches an attack, later known as The Battle for Europa.
