In the year 200X, a set of 6 different robot masters started to wreak havoc all over the world. Feeling a strong sense of justice, Dr. Light's personal helper robot decided with Dr. Light's approval to be converted into the super fighting robot known to all as "Megaman." <br /> <br />On three separate occasions, Megaman managed to stop the evil Dr. Wily from controlling the world by filling it full of robots all the way up to his death after the destruction of both his 2nd Castle Fortress and Gamma. It would seem as if at long last, peace has finally been restored... until now. <br /> <br />Set one year after the events of Megaman III, a new Russian Scientist by the name of Dr. Mikhail Sergeyevich Cossack created 8 Robot Masters of his own and now challenges Megaman into defeating him and his army of robots. It would seem as if once again, Megaman must do what he can to preserve peace. <br /> <br />This time around though, Dr. Light modified his Plasma Armcannon into the new and improved Mega-Buster. It can still shoot Plasma shots like before, but now it can be charged up to two different settings, a level 1 charge that is slightly stronger than a standard Plasma shot, but otherwise is about as effective as a standard shot. <br /> <br />The level 2 charge however is a fully charged Mega-Buster shot that can do far more damage than his standard shot and if it does enough damage, it can also pierce though an enemy and go after the next one. Considering how serious this Dr. Cossack is, Megaman will need this to help him out, as well as getting more help from a new robotic buddy, Flip-Top (Eddie) who can give Megaman some needed health, weapon energy, spare bodies and even some Energy Tanks.
