"Imperial Walkers on the north ridge." - Control Officer
Playable Vehicles: SnowSpeeder
Enemies: Probe Droid, AT-AT
True Jedi at 4,500: Not too hard. The Probe Droid's give the money here, and they constantly respawn, so there should be no problems getting the total.
This level isn't very long. With the SnowSpeeder, the A button fires the tow cable. All you need to do here is defeat the 4 AT-AT's on their way to the Rebel Base. Lock on with the Tow Cable, then circle the Walkers to bring them down, then shoot them to finish them off. Once all four are defeated, the level ends. Seriously.
Unlocked Vehicles: SnowSpeeder (4,000)
