Mega Man II

Mega Man II, known as Rockman World 2 (ロックマンワールド2) in Japan, is the second Mega Man game for Game Boy.

Overview
Like its predecessor, Mega Man: Dr. Wily's Revenge, Mega Man II reuses content from the NES games, both graphics and actual level construction. The first four available Robot Masters are from Mega Man 2, while the last four are taken from Mega Man 3. The game also introduces many of Mega Man 3's features to the Game Boy series. Mega Man is able to slide. Rush also appears for the first time in the Game Boy series, allowing the use of the Rush Coil, Rush Marine, and Rush Jet.

Story
From the japanese instruction manual: ''In Rockman World 1, Dr. Wily was defeated by Rockman. Even with this crushing defeat, he was already planning his next scheme when he came upon a devious idea. If he could get his hands on the time machine that was being developed at the time-space research laboratory, he thought he just might be able to change the past. Yes! If Dr. Wily could return to the time before he first started his rebellion, back to when Rockman was still just a household robot, and launched a surprise attack using his strongest robotic forces, there would be no way he could lose!

Several months later, Dr. Wily had succeeded in stealing the time machine from the time-space research lab. He had wanted to set out immediately on a trip across time, but had to put an emergency brake down on his plans when he discovered that the time machine had a serious flaw.

Meanwhile, Dr. Right had been dispatched to the time-space laboratory to investigate. With the help of Rush’s super-sense of smell, he was able to deduce that it was none other than Dr. Wily behind the theft. Having a bad feeling about the incident, Dr. Right quickly called upon Rockman and Rush to search out Dr. Wily’s whereabouts.

Before long Dr. Wily had finally managed to modify the time machine. However, the time machine could now only travel into the future and back, not into the past. Dr. Wily modified his plan and decided instead to spy on Rockman’s future. He found that in the future Rockman had been reset back into a peaceful household robot. Recognizing this chance, Dr. Wily conspired with his own future self to bring this battle-functionless Rockman back in time and alter him to make him fight against the Rockman of the present. Back in the present time, Rockman and Rush were finally closing in on Wily’s fortress, mowing down even the strongest enemy robots in their path. But little did Rockman know that he’d soon be facing off with his own future self……''

Wily once again revives a new set of Robot Masters, four of which guard his underground fortress. Dr. Light sends Mega Man at once to take them down and penetrate Wily's lair, but once inside, Mega Man finds another four Robot Masters awaiting him via teleporters. Mega Man manages to defeat all eight of his adversaries and engages Quint in combat, defeating him and obtaining his weapon, a pogostick-like device called the Sakugarne. With it, he makes his way to Wily's space fortress and defeats him yet again.

Final Boss
After you have defeated all of the bosses, Mega Man must fight against Dr. Wily, who is using Wily Machine World No. 2.

Trivia

 * The sound effect when the player picks up an extra life is very reminiscent of the coin pick-up sound from the Super Mario Bros. series.


 * This is the only Mega Man classic Game Boy game to use Rush Marine.
