SIDE QUEST:
We have a small problem over at the OLD FACTORY (world 3).
The tech guy said that a giant mech was malfunctioning, then the SECURITY EYE went berserk!
Use your FIRST ARMOR X to complete World 3 in CHALLENGE MODE, including stage 3-6. Next, use the FALCON ARMOR X to repeat the boss battle against the MECHANICAL EYE on STAGE 3-6. Use the HOWLING STORM Cannon when using your Falcon Armor X.
