HP: 56
Weakness: Acid Barrier, Chain Blast
The Wily Machine shoots large rockets while moving around the room. It’s a massive target but can only be damaged at the skull’s eyes.
If it’s in range, use the Power Gear with the Acid Barrier to deal critical damage. If it’s too high to be shot with the acid bullets, use the Chain Blast, as they’ll automatically attach to the Wily Machine’s weak point. Using the Acid Barrier has the added advantage of blocking Wily’s attacks.
After taking 50 percent damage, the Wily Machine will lower two large gears that it uses as wheels. They, too, are especially vulnerable to the Acid Barrier and Chain Blast, as well as the Pile Driver. When you destroy the gears, the Wily Machine drops to the ground, allowing you to more easily land Acid Barrier shots and finish it off.
