Cloud City 4-40

Cloud City 4-40 is the last level of Cloud City. To pass this level with three stars, you should pop all pigs and score at least 72,000 points.

Difficulty

 * Darth Vader's lightsaber can destroy blocks and ricochet birds, so it's almost impossible to win for some when encounter him in the first time.
 * With only three minor boss pigs, it's hard to make a higher score
 * Defeating Darth Vader gives you only 5,000 points.
 * Three compressors move up and down, so it's harder to aim for the perfect shot.
 * The 3-star target score is extremely high. 72,000!
 * This level requires massive amount of luck.
 * Leia's Tractor Beam can kill Darth Vader (without Lightsaber) if he is close and the compressor #1 is not in Leia's way.
 * Darth Vader jumps from platform to platform so this makes him harder to eliminate.
 * If you finish all pigs and use Luke to kill full-sized Vader instantly, you'll earn the new achievement. But it's really difficult to earn since the compressors and Vader are moving.
 * Overall, completing this level is extremely hard and getting three stars is almost impossible.

Strategy

 * Use at least birds as possible.
 * Detonate as most TNT as possible.
 * Send blocks to Darth Vader as most as possible to destroy his lightsaber.
 * Use all five birds to kill all minor bosses and use the last bird: Luke to kill the boss instantly, but you can never get three stars. Not to use more than five birds to get three stars.

Trivia

 * This is a seventh boss level.
 * You can complete achievement: “Who’s Your Daddy Now” in this level.
 * When you kill Darth Vader, everything is in super slow motion for about five seconds.
