My 2nd favorite game in the MMX series, it's a perfect sequel to the first MMX
Not only you need to battle all bosses but also the X-hunters to help Dr.Cain reassembling Zero (if not you can fight Zero before Sigma's boss fight)
The weapons are good in this game, didn't had problem using theme or them being boring/useless (I still can't understand Magnet Mine's black hole)
The armor is a great improvement of what the first game gave us (which will later inspire most armor upgrades), you don't dash anymore but air-dash with the leg part, the buster shot is...... I definitely don't know what to say on it but it's just too long to wait until the fourth charge besides that it's better than having to charge super long just to waste everything, with 2 shots you can manage the time to use them, the body part can let you accumulate damages to charge the giga crash (useful against mini bosses or for several enemies at the same time) but also reduce received damages by 50% just like the first one. The head part who even talks about this one ???
The game difficulty just like MegaMan 5, it let you win, giving a impression that the game seems easy compared to X1
Soundtracks is a BLESSING !
The main bosses are good with new mechanics but just like I said in the game difficulty, they're relatively easy to get a win against even without their weaknesses, the real deal in difficulty are the X-hunters and Zero
Sigma's boss fight, it's still like the main bosses he's easy to pull a win even without his weakness, his attacks are too predictable and easy to dodge. In his virus form the difficulty is slightly higher but I'm not gonna talk about that one.
Gameplay I don't know what to say on it but I found the same result as the previous game
