pretty good
The game introduces this new style of game-play called bio-metals which change the appearance and the strength of the character you chose in the beginning.
The bio-metals are really great in that each BM has its own strengths that can be utilized. Such as the X metal which gives you great long range attacks which prove to be good later on. The bad thing is the loss of X later on. You get ZX which stays with you for the rest of the game along with the other bio-metals you can find. There is a way to have model X for the rest of the game and most likely you already know how. For those who don't know, find it out yourself.
The game is short in my opinion, but then again all the megaman games are. It has the usual 8 bosses and then the 4 final ones, just like any other MMX or MMZ game.
The graphics are about the same as the MMZ games, except that there are a few anime cut-scenes.
I never really notice the sound but from what I heard the sound is good. The music tends to match the level which is good. The cut-scenes are subbed meaning that they are speaking in Japanese with subtitles on the bottom. This tends to be a good thing because English voice-overs are not as good as the Japanese ones.
The learning rate is easy because of the ability to change the controls. The difficulty can be changed when starting a new game, having the classic easy and normal modes. Hard mode has to be unlocked. Easy mode is just that easy and should only be used by those who have never played a Mega Man game before. Normal mode is for those who have played Mega Man games. Hard mode is for those who would like a challenge.
This game also has the function for your character to fight bosses from MMZ3 and 4 provided that you own those games.
Overall this game gets a 8.1 because of the awesome bio-metals, the compatibility of the MMZ 3 and 4 games, and the cut-scenes.
