Blops hidden areas and tricks

I wouldnt call any of these glitches most of them seem to be built the way they are and the rest just seem to be a matter of jumping. none of them are really that hard to do, and even if you dont care to use them its good to know they are there so you can spot someone that might be camping one of these spots.
