Mega Man Zero 2
I've had MMZ2 for quite a long time, but have never gotten farther than the end of the intro stage - this game is damn hard, I would say moreso than the original which was already a little masochistic. Tonight I finally buckled down and polished off two of the first four bosses.
In true Capcom style the sequel additions are fairly scant: a grappling hook and some "forms" that I haven't made much sense of yet. Otherwise thus far it's pretty much the same old story in a new box.
Progress: Finished 2 stages
