It dont look like much was changed , just a few little things.
not mine just found it from a twitter link
The problem is, the few changes they did make, created more camper friendly spots, where people can get more cheap kills. The beauty of this map, was that it had just enough cover, not too much. People had to keep moving, or defend an area AS A TEAM. They made the map look like crap as well. IW/SH taking a perfectly good thing and ruining it once again. They really are mental midgets.
