Megaman Battle Network 6: Falzar GBA

A long time ago two ancient creatures with unimaginable power ravaged the net. These two behemoths called "Cybeasts " clashed against each other with such force that the entire virtual landscape was changed forever. One embodied the form of a vicious wolf with massive fangs and horrific howls that reached far and wide. The other was a ferocious bird with razor sharp claws and immense wings that flapped mightily blowing over everything in its path. After their last known battle a giant crater was all that remained and it was named the Underground where they have lain in slumber... until now. Through the actions of a mysterious foe they have been awakened and unleashed upon the net. Mega Man is able to intervene and manages to successfully contain one of the beasts within him. In addition to the shifting story new features change up the gameplay. A new "Cross System" allows Mega Man to utilize the special power of allies in battle. Mega Man will encounter several "Link Navis" along the way which when defeated will lend their own cross ability that can be used in battle. Though very useful each has a particular weakness. Another powerful advantage is the "Beast Out" system resulting from Mega Man's absorption of the powerful Cybeasts. The option to use the ancient monster's power during battle will become available offering a boost in speed ability to rapid fire Buster shots double a Battle Chip's attack power and more. While a Cross is equipped Mega Man can also Beast Out combining the forces of these two systems to maximize the power of the Crosses even further. However the use of the Beast Out system is very limited and if Mega Man becomes fatigued he may succumb to an uncontrollable overdrive mode called "Beast Over." In this state Mega Man will be very powerful for a short period of time but then when he is released from this mode he will be left in a very weakened state close to dying.
