Mega Man 3/Wily Fortress 3

Again, Wily's fortress provides another pretty straightforward area. Just keep progressing through the level, destroying any enemy that gets in your way. The Star Field Projectors from the Shadow Man level reappear here, and to be on the safe side, you'll want to take them out before moving on. Fortunately, most of the enemies in the level aren't that hard to defeat. Just keep moving forward.

For the boss fight, you'll be pitted against three Mega Man Clones, each on its own platform. The catch? Only one of the Mega Men is vulnerable to attack at any given moment, and they shift vulnerability throughout the fight. You'll want to rapid fire whichever one is currently vulnerable, making the rapid-firing Needle Cannon an ideal weapon for this fight. Just stay on the move and fire away at the vulnerable one, and you'll win in no time flat.
