One of the better classic MegaMan games, except the fact that it was incredibly easy at the time.
The story behind it is very similar to MegaMan 4. Dr. Light has been kidnapped by MegaMan's older brother ProtoMan (who is actually a robot made by Dr. Wily in disguise), and MegaMan must defeat 8 robots along with the robot who framed his brother and Dr. Wily in order to save his creator.
As like most MegaMan games, the control and gameplay hasn't changed a bit. Well, except the fact that you lose your charged shot when you come into contact with enemies so be careful.
The only thing that I probably like and DON'T like about MegaMan 5 is how amazingly easy it is to beat the game. The only major challenge you'll come across is ProtoMan and Dr. Wily's castle to a slight degree. The robot masters have incredibly easy stages to navigate though.
In reality, MegaMan 5 is still a good game. It still won't dethrone MegaMan 2 however
