Sonic Mega Collection Plus

The Doomsday Zone in Sonic 3 and Knuckles on the Sonic Mega Collection Plus. This is the special Final Boss fight in Sonic 3 and Knuckles if you manage to get all the Chaos Emeralds, and during this level, you play as Super Sonic while flying through space. It's also a race against time as your ring count depletes, and if it reaches zero, you lose a life. In the first part, it's best not to hammer the buttons and speed up, as you'll miss out on valuable rings, and be sure to go for sets of rings that appear in large clusters, while avoiding the asteroids and rockets. When you reach Dr Robotnik's Spaceship, you have to lure the homing missiles being fired at you on to the cockpit of the spaceship until it goes down. The second part of the boss is chasing down the giant mechanical Robotnik carrying the Master Emerald, and hit him until he is beaten. Not too hard for a last boss, if you know what you are doing.
