Mega Man 2 is a platforming game for the Nintendo Entertainment System.

Following the gameplay of the first Mega Man game, Mega Man 2 has new features, like Robot Master stages increased from 6 to 8, E-cans that replenishes health to 100%, and support items/platforms 1, 2, and 3.

After his defeat, Dr. Wily created his own Robot Masters and continued his desires for world domination. Mega Man is the only one who can stop the evil scientist once again. But before he could reach him, he needs to defeat Dr. Wily's Robot Masters and obtain new powers from them.
