From the Game Manual The Empire's revenge has begun! Right now an army of Imperial Walkers is marching toward the Rebels' power generator on the Ice Planet Hoth. If they reach it, the entire Rebel base will blow sky high! To stop them, the Rebels must rely on their missile-firing Snowspeeders. The Snowspeeders may be tiny (compared to the gigantic Imperial Walkers) but they're quick and agile. And in the hands of a skillful commander, they can destroy the mighty Walkers! So climb into your Snowspeeder and be prepared to meet the first of your deadly enemies!
