Campers is a one of the biggest problems

I always felt that if you got farmed by a "camper" the problem is you. You have the information on his whereabouts, in most games (especially fps) thats more than enough to have the upper hand

in some games spawn is at the same point every time, even if one of the bases is captured, so spawn campers are what annoy me, if they are in a frequently used tunnel, then yeah its the other gamers fault

In Games which include shotguns and poison gas grenede, campers are a headache.
