There are friendlies out there. There seem to be an abundance here on the forums. Personally, I get myself an advantage over someone and then try to communicate with them. It helps to have a mic too. The time it takes to type makes people very nervous. I try to help unarmed people and fresh spawns with some items, I never hand out weapons though for obvious reasons. Also, if someone is running along with a coyote back and an AS50 then I will probably shoot first. The odds are that they are bandits and what is in their pack is better in mine. Just be cautious, if someone isn't a threat then do what you will. Don't give away your position until you feel that you can come out on top if it goes awry. Happy surviving.
