It has been twenty years since the first, savage wars against the Synod of Worlds. The Terran Alliance has grown much in the last two decades of relative peace. Former Synod worlds within the sector have joined with us and our allies. Members of the Preservation Society have flocked to our banner and provided a desperately needed resource of information and technical expertise. The shipyards of Titan and numerous mining operations within the asteroid belt and small moons of Jupiter and Saturn have built the largest fleet in Human history. Our close allies, the Aven and Fel'akin, have trained with us and a mutual respect and admiration have grown out of the desperate years of the first Synod War. The Sector, however, will never be safe as long as the Synod controls the galaxy. The Synod scourge must be eradicated. Task Force Alexander is composed of nearly three hundred warships and four hundred thrity five transports. The 1st, 2nd, 5th and 7th Marine Divisions along with the 1st, 2nd, 3rd and 5th Terran Legions form the backbone of the invasion ground forces.

Fleet Admiral Harlie Mason commands the combined forces. Their First Target is to break into the Hevan Sector through the Qetesh Gate system. Soon they will be knocking on Hevan's door. 'Gatecrasher is the 1st in a series of campaigns to liberate the Hevan Sector from the oppressive and genocidal rule of the Synod of Worlds.
