Lol this game is 300% easier in daylight for beginners.
So I spawn, this time I can see buildings in the distance so I go there (in think it was the airfield but I'm not sure), loot useless things but maybe an xbow. Without bolts for it of course. After I take it I hear makarov shots so I very cautiously try to find where's the guy, but I don't find him so I continue exploring the hangars, pretty much nothing in them. I proceed to a building next to them. There's a ladder to go up, I use it and as soon as I'm up there I see a human crouching and aiming at me. He quickly goes down the stairs he was next to for some reason so I have no choice but to stay on the roof. I ask if friendly in chat but because of my severe noobishness I probably did it in the wrong chat. Then to my despair a zombie climbs up the ladder (wtf asshole xD), looks at me in the eyes then proceeds to go down and follow the other guy. I hear gunfire and the zombie hitting the human so I climb down the ladder as I suppose it is my only chance to catch him with his pants down, friendly or not. When I'm downstairs I see him eating or something like that, not even facing my direction, and I also see he has a hell of a lot of loot (compared to me of course). The combination of greed and the fact he was completely harmless pushed me to kill him. So bam I get a lot of things including an ALICE pack, more ammo, a weapon... At that moment I hear someone going downstairs. And fuck it's not a zombie. I say my usual "hi", probably again in the wrong chat, then something along the lines of "let's share the loot" because I do want to play it friendly and obviously that would not happen if I kept it all for myself. The answer was a bullet in my head.
Roleplaying a mute guy is hard. It's not very surprising the more aggressive people are those that only have the equipment they spawned with.
