From the moment that Captain Xod's face appeared out of the static on the communicator, you knew he was in trouble. As the only other Federation ship in the sector, you had to go to his aid. You need to fight your way through 16 zones, collecting essential supplies for the fleet. At the end of each sector you have a chance to refuel and restock but only after you have defeated the most vicious alien you have ever seen! You have the option of swapping between two very different craft, to suit the challenge facing you at the time; either a ground-based saucer or a well-armed and faster fighter craft.
