Star Wars The Empire Strikes Back (Atari 2600)

The Imperial Walkers are approaching the Rebels' power generator on the Ice Planet Hoth. Unless you can prevent them, they'll blow up the entire Rebel base! There's still time, so blast off in your Snowspeeder and try to destroy the Imperial Walkers with a barrage of missiles. It will take all of your skills as a pilot and all of your daring as a Rebel!
