I have destiny on the ps4 and I just played 2 missions last night, I noticed there are a million people running around but they dont seem to be playing co op with me... how do I get people to join my games? Do they have to be on my friends list and invited?
If you look at a player and press R3, it should bring up the fireteam menu. You can send an invite from there. Aside from that, they are free to help you with whatever you are doing, or they can go about doing whatever they want.
