Okay, so get this- despite all appearances, this is in fact a brand new Mega Man game. Capcom have just made it in the style of a NES game, right down to slightly sluggish controls. They've done this because... they're monsters? We're not sure.
One thing OXM is sure of is that this game is blindingly, scrotum-dissolvingly hard. Harder than not just any other platformer on Xbox Live Arcade, but any other level based game available on the 360. Which is to say it's as hard as your average NES game. Just beating any one of the eight robots you're up against (now featuring one ladybot) is a triumph, and storming Dr. Wiley's endgame fortress is a terrifying prospect.
