I been playing alone since day 1, i been up there in NW airfield gearing up and been killed when open a door once or two times, yes is has made me more paranoid and always try to avoid big city, but when i run out of supply I scout very carefully and always close the door behind me and with a gun in my hands. I havent had ANY interaction so far with any players ( only saw my killers) so I do feel lonley sometimes but I do spend few hours on the servers because in the end I love the game. Everytime I need to re-gear and need decent weapons I do take the risk and go in places like airfield and military bases, BUT I take what I need if I found a M4 and a gun with enough ammo I am good to go I dont need the fancy guns or the latest and best scope, as long I got what I need to defend myself I can SURVIVE or DIE trying.
