Dr. Robotnik appears at the beginning of the Launch Base Zone in Act 2 and starts throwing metal balls at Sonic. Dodge the balls, and use Sonic's Shield Attack to hit the machine eight times. The machine falls into the water, and Dr. Robotnik appears with a second machine.
The laser shooter machine fires at Sonic rapidly. When the machine dives in to attack Sonic, the player needs to jump and attack the lasers to destroy them. It takes eight hits to destroy all of the machine's lasers. Sonic needs to hit it one more time in order to make the cockpit explode.
