In a typical 2D platformer format, you will fight your way to the end of the stage, only to meet the boss who is hell bend on killing you because his boss said so. Sometimes, you will meet mini bosses as well (Talk about middle management).
Once defeated, you will be able to "copy the enemy's DNA". That enables you to "A-Trans" and takes on its form and ability. In simple English, that means once you have defeated the boss, you can transform into it to wreck havocs whenever and wherever you want. And this is where the game excels.
Given the size of the middle management (15 in all), Mega Man ZX Advent provides you with plenty of models and fire power at your disposal. Each of the bosses has its own unique sets of ability that will help you in your quest to quash the evil plan. Some models allow you to float in water, others let you grab onto poles, there is even one that let you go through walls. The key to this game is to use the right Mega Man at the right time.
