Three Star Walkthrough
Launch Han Solo towards the top right steel wheel. While in flight, aim your Blaster midway at the supporting triangular wood block. This should cause the “crane” to collapse to the left, and allow Han to continue his flight towards the last pig. With a little luck, Han can go through the blocks and detonate the TNT for extra points.
Launch Han Solo towards the southern hemisphere. While in flight, shoot the TNT which is in the southern structure. This should cause the southern structure to collapse. Allow Han to continue his flight towards the crane or leftmost TNT crate. Kill the remaining pigs.
