Playable Characters: Millennium Falcon
With Echo Base lost, it's time to make sure that the Rebels can get past the Imperial blockade in orbit around Hoth. Pilot the Millennium Falcon through the swarms of TIE fighters and TIE interceptors and make your way to the real targets -- the massive Star Destroyers. Luckily, you don't need to take out entire ships, just their gun turrets. Fend them off long enough for the Rebel transports and escort frigates to escape.
With your allies out of danger, Han flies the Falcon into an asteroid field to ditch the pursuing Imperials. Getting through the field is made even more dangerous by the asteroids embedded with explosive mines. By shooting these booby-trapped rocks, you'll discover a proton torpedo hidden within. These torpedoes must be collected and used to blow up massive asteroids that block your way. Keep in mind that you'll also have to deal with attacking TIEs while all this is happening.
Chapter 4: Dagobah
Playable Characters: Luke Skywalker (Pilot), R2-D2, Luke Skywalker (Dagobah), Yoda
As in the film, Dagobah is where Luke begins to learn the ways of the Force. During the first part of the stage, Luke (still in his X-wing jumpsuit) and R2-D2 must maneuver their way through the planet's swamps in order to find the mysterious Jedi master named Yoda. Piles of LEGO bricks can be built into ladders and bridges to assist you, and you'll have to deal with wild creatures like bats and giant snakes.
Once you find Yoda, Luke's training begins (and he gets a change of clothes). Since the farm boy's powers are still weak, carrying Yoda on his back will allow Luke to use Force powers as you continue through the swamp. Eventually, Luke's powers manifest themselves, and he demonstrates them by building a tractor out of LEGO bricks. We don't remember that part from the movie either, but it was still pretty funny.
And yes, you will enter the cave that is strong with the dark side of the Force and confront the vision of Darth Vader.
Chapter 5: Cloud City Trap
Playable Characters: Luke Skywalker (Bespin), R2-D2
The duel with the phony Vader was just practice for the real deal here. Luke and R2 arrive on Cloud City and find it crawling with stormtroopers. The duo starts working their way through the city, using R2 to open up any locked doors as they go. Soon, they encounter Vader in the carbonite freezing chamber. As Luke and Vader fight, you can take control of R2, who can interface with a computer terminal that causes vents in the floor to expel gases. If Vader is standing on one of the vents, he'll begin coughing and become stunned for a moment. Use this chance to take control of Luke once more and deliver a few lightsaber blows.
Eventually, Vader will flee, forcing you to chase after him. You'll end up fighting the Sith Lord a few times throughout the city until the final, climatic scene in the city's central air shaft. I won't spoil how the non-speaking LEGO Darth Vader reveals Luke's true parentage to him, but it sure got a chuckle out of me.
