Mega Man IV review. Shop CGR shirts & mugs! Classic Game Room presents a CGR Undertow video review of Mega Man IV for Nintendo 3DS, developed by Minakuchi Engineering and published by Capcom. Mega Man IV isn't Mega Man 4. Well, half of it is. The other half of Mega Man IV is Mega Man 5. Have you caught all that? Right, because it's exactly what they did the last three times. This time, though... y'know, there's not really a "though," there. It's exactly what you're expecting. And it's slightly better than they did last time, so you can claim "progress!" C'mon, you can't honestly say you didn't see this coming. This video review features video gameplay footage of Mega Man IV for 3DS and audio commentary from Classic Game Room's TJ.
