Our race is in a fight for survival against the Katuri. Granted, we did invade their space and try to take over their worlds, but that's somewhat beside the point now. Your mission is to man the guns of the Antaris and protect the resupply freighters as they make their way to the 5th Fleet. The Katuri are determined to wipe you out, though, and if you make it through their fighters, you'll eventually face the dreaded Katuri Juggernaut Carrier!
