Seriously? BO and MW3 were full of them. I don't remember the names of maps, so I'd have to go look them up. The big maps not so much, but small and medium ones have them.
The only thing I can really think of in MW3 was the city one in France(I think) near the back alley, but even then, there are FOUR different ways to enter the back side and kill a person.
Also, that's not camping, but rather sniping in a traditional sense, especially if you're covering a certain spot(B). That term "camping" have changed and used in the wrong term so much within the past 5 years. Camping is literally proning/crouching and guarding one entrance. A great example would be the desk on the 2nd floor in Nuketown and you're guarding both entryways. That spot isn't very advantageous though. -
Blue, yellow, pink, whatever, man, just keep bringing me that.
