Star Wars (Namco)/Iscalon

Fall into the water to start swimming. You only have your saber for this part. Swim to the right, killing or avoiding the fish, and carefully navigate through the spiked barriers. Kill or avoid the jellyfish and continue to the right. Watch out for the giant fish. It's probably easier to kill it than to swim through the spikes. Swim down and break the sun blocks, then swim right. Grab the extra life and head back left. Swim down, killing or avoiding the squid and giant fish. The left-hand path has giant squid while the right-hand path has sun blocks but is harder to get to safely. When you reach the bottom continue to the right (watching out for giant fish) and swim into the doorway. Here you'll fight Vader as usual. Hit him once and he turns into a shark. To fight the shark swim around behind it and slice at its back, then back away when it turns around. After four hits it's dead. Head right, swing your saber, and rescue C-3PO. Now you have to rescue Leia from the Death Star.
