arg wrong forum, can someone move it?

you can turn pking on and off

and even if pvp is enable you can still do coop, form a party and go together out, will save your life maybe sometimes to have a good wingman or an escort for your frighter ^_^

I meant co-op like for the single player missions (i guess there's a reason that they call it single player), but any chance to do those co-op?

You cannot play the storyline in multiplayer. After all you are just one guy (Trent).

than what do you do in multiplayer if you cant follow the story line?

You... tadaa.. freelance

There are quite some possibilites. A goal pretty much anyone has is making cash of course, and doing that by means of trading is the most effective one, I think. You can also join the dark side and attack convoys, "hack" trade lanes, smuggle contraband.. or you stay with the good guys and hunt down the evil pirates. Point is, there are other players out there who you can team up with, fly missions together, or ask them where to find item xyz, maybe they'll fly you there for free.. maybe you'll have to pay them.. you can be hired as an escort if someone wants one.. etc.

But there is a problem when you team up and coop. Sometimes a group is hostile to your bud, while hes friendly to you. So what do you do? Attack him and screw up your rep or let your bud die?

Co-op is not easy in MP. You always have to wait your friends to respawn and rejoin you (dead player respawns in the last station he docked so some times it takes a long time) or your friends have to wait you.
For example, I can fly a Rheinland freighter to Omega-41 from Stuttgart alone in 20 minutes. The same route takes more than 1 hour when I was flying Titan and my friend flied an Eagle.
