It is your job to stop them. That's basically where the 17 missions take you. But the storyline really doesn't come into play that much. Most of the time you'll just launch and begin to attack any bandits that enter your screen. The storyline is unimportant, so if you're looking for an interactive movie, look elsewhere.
Game play is fast and furious.
You and your wingman will take on many bandits at a time. With a variety of capital ships and fighters, you'll have your hands full trying to stop the border incursions. You are armed with a standard fare of weaponry, from heat seeking missiles to tactical nukes. You also have, of course, your trusty plasma guns and auto cannon to dogfight with. A unique feature of the game is the probability of crashing into a destroyed ship's debris.
