Mega Man 4 is the pinnacle of the NES Mega Man games. High attention to detail, beautiful background to foreground contrast ratios and amazing controls. Enemy placements are some of the best you’ll find and using the multi-purpose weapons is a true joy that doesn’t stop giving.
Only a few flaws are present. However, it is not enough to sour the experience. Robot Masters can be a bit on the boring side and just a few bad rooms are present. All of those little flaws are nothing compared to the full package: There is no better Mega Man experience on the NES. Along with its amazing soundtrack, Mega Man 4 sets a high standard that all fan games should follow. If you’re only going to play one of the NES games, make this the one you pick up.
