Yeah... but if you havnt got enough on multiplayer you can get you and two others. One take a gunship and load it with AI players, and the other two take jedi fighters. the fighters are quick and can destroy the AA guns before the gunship gets to that end of the map to drop off the AI who capture the CP. If the area is safe one of the fighters can land and help out the AI, while the gunship can land too, and the other fighter circles the platform.
That's simple enough if you're just playin for fun or a more relaxed game.
