Futuristic soldiers are sent to intercept an unknown space vessel and find themselves in a fight against an invisible enemy that they can not kill.
The AstroGuard (AG) sends Bravo Company to intercept an unknown vessel that has crossed into UPA (United Planets of America) territory. The vessel fails to respond to all forms of communication and long range scanners can not determine anything at all about the ship other than its massive size; it is simply classified as unidentified. The nine member Company sets off to intercept the ship on their new MX4 class Interceptor named The Violent Sun. When they arrive at the intercept point they find the other vessel to be completely abandoned and lifeless. After boarding the ship they are ordered by their Captain to obtain any information they can about the "alien" ship. In the process of exploring the large ship curious sounds, fleeting images, and haunting memories start to assault them. After two members vanish without a trace Bravo Company suddenly finds themselves in a fight against an enemy they can not see, can not touch and can not kill and they may have only one option to survive; complete destruction of the ship and everyone on it.
