To me that was the best part of the update simply because I didn't expect it. If Black Ops has told me anything, I expect in two weeks someone will have figured out how to make the women look completely naked and all sorts of other monstrosities, but the potential of the decals is actually really awesome.
Also the new stages are awesome. Still missing Dr. B
I had a chance to mess around in there a bit today; with the exception of a few color limitations here and there, the possibilities are endless. It will be interesting to see what people come up with--I already miss summer time, so I'm going to start out with some Hawaiian shirts and the like for my crew.
