"Let's talk about that last part -- difficult. Forgiveness is absolutely not one of this game's virtues. In all fairness, you can say that about most of the classic Mega Man games, but MM9 routinely ratchets up the challenge a couple of notches past "insane." The structure's fundamentally unchanged: You guide the titular character through eight themed side-scrolling stages (in any order you wish), armed with a simple gun and an ever-growing arsenal of useful weapons nabbed from an octet of android bosses -- who each exhibit weakness to a specific weapon. So, your task is twofold: Survive each successive gauntlet and deduce an effective kill order (some charitable advice: Start with either Splash Woman or Galaxy Man)."
