The music is interesting, with a music mix from other classic games like Final Fantasy 5,6, Chrono Trigger, Rockman 7 and more. The level design is unique and holds a great flow. If you want to play a hack based off of Megaman 2 that is very technical, hyperactive and has amazing enemy and boss AI, Deus Ex Machina is the hack to play.
Also, Megaman can jump a little higher in this one! It’s one to fun play through, but for most hardcore Megaman players the challenge will be lacking. It’s pretty awesome climbing up and down vines and shooting Goombas with your laser cannon. The levels are all impressive and the design stays true to the Super Mario Bros series throughout the hack. Megaman In the mushroom Kingdom features levels, enemies and bosses from Super Mario Bros, 2, 3, and World. If you love Super Mario and Megaman you will love this crazy crossover. I guess just think of it as a good DLC for Mega Man X, lol. Overall this one is not too unique but provides more if you loved X.
The bosses remain the same, but these new levels are very fun to play through if you are a fan of the original game. Mega Man X: Generation is basically a completely newly designed game based off of X.
