The Battle of Naboo was the spark of the great Clone Wars, even though Geonosis was when the first battle began. Naboo's loss made Nute Gunray furious and so he alligned himself and his droid armies with the Separatists. The Naboo pilots had to make their way to their fighters and destroy the Trade Federation Droid Command ship. In this siege map, you start out on the streets of Theed, then you make your way into the hangar that you can now spawn in after you capture it, and fly up to the droid control ship and destroy it, while the other team attempts to protect the ship. So the main idea is to take out the radar dishes, command towers, engines, and other critical systems to lower the shields protecting the reactor core. Then you fly inside the command ship and destroy the reactor core and fly out without getting killed.
