In my experience a lot of that is untrue.
STORY TIME.
I just spawned and had nothing to lose, I was by elektro where Teeny Moo and Ruben were so I decided to go into town and get some shit. As I was crawling to the super market someone says "GUY NEXT TO STREET IN ELEKTRO, FRIENDLY?" I responded with "is he prone" and he said yes. I said I was friendly and got into the super market, in the back area. I heard a very loud gunshot like an enfield and asked if it was him shooting. He had misfired his m4 and he was actually in the super market too. I warned him of zombies coming from the back and I helped him finish them off. We asked if we needed anything, but unfortunately STAANAG'S and ALICE packs aren't exactly abundant, or so we thought. We decided to help each other out for a bit, and began heading towards the school. We stopped at the apartments in front of the school and low and behold, an ALICE pack. I thought to myself, if he wants to kill me, this is when he's probably going to do it, but all he said was "nice" and kept looting. Feeling glad about finding a friend, I told him that we were going to find one for him too. We went down to the school, looted some more, got a winchester, compass, other things like that and found TWO ALICE packs. He said thanks and we happily went on our way to the hospital, in need of medical supplies. We checked the roof and the back but to no avail, already looted. I then said "Let's try the front, I'll guard while you shoot" To my horror, he used his m4 to shoot out the hospital glass and attracted a SHITLOAD of zombies. We fended them off, wasting all my m1911 ammo but getting 3-4 bloodbags each. I told him that this is where we depart and we both said thanks and good luck, heading off on our own ways. I returned to the others, fully supplied after respawning, and feeling great about meeting a friendly.
Also, I actually started a pretty neat and serious discussion about the development of the mod, some of those people are dedicated to their opinions though ._.
Yes, well, there are some exceptions, but that is rare.
So I was in elektro too. Fully packed and shit. Alerted 1 zombie at the firestation, all of them came there after a minute. I was there stuck with a revolver and a lee enfield.
Some random guy who couldn't use the chat button came there and helped me.
I was like okay, thank you and went on my way.
I went to the church. Found some food but my backpack was full and I had a cz in my backpack. Dropped the sniper and bam, got shot in the neck.And guess what. It was the same guy who saved me. He probably killed me 'cause he wanted the cz. (Which I dropped).
