No, they fixed the all black zombie thing (they are not really zombies actually), now it is kind of funny as hoards of black guys jump out of nowhere and back you into a corner and you spot a random white guy or two mixed in there just for good measure.
I remember back when you'd here people complain about the absence of black people, now if there are too many you are in trouble. I mean, you are in some remote African village, that is the only reason everybody was black at one point. Nothing at all to do with racism.
