Mega Man (NES) Part 9: Wily Stage 3 + CWU-01P Boss
5Wily Stage 3 is just a narrow passage. First, Mega Man falls downward in it, then he must travel east. When this happens, the tunnel quickly fills with water, and its pressure keeps Mega Man from going back to the left.
When Mega Man reaches the end of this path, he has to take down several bubble-contained robots called CWU-01Ps They appear from one of three sides of the area, and rolling around on the sides while shooting at Mega Man. As Mega Man destroys one, the next one that appears is faster than the one before it.
I had to experiment with weapons for a bit. A good strategy to use is using the Super Arm on the left, right, and top blocks, but not the center block. Each block will instantly destroy the first three robots, and the one left will help you dodge the remaining ones as they swoop through the bottom side of the area.
On the the very last robot, the one marked with red and is the fastest one of them all, that's when you use the remaining block on it.
Despite the struggling I did here, stick with using the Plasma Cannon/Mega Buster on the all the robots except for the 1st, 2nd, 3rd, and last. It apparently destroys the robots faster than any other weapon that Mega Man can use besides the Super Arm.
