I suggest you go ahead and go MP.. I have never played SP Freelancer or SP Crossfire.. just jumped right into MP.. and I've never done a mission. (the 2nd ranked CF player ever never did any missions either!) I haven't had any problems finding my way around or getting help from other players in MP. Everyone is very helpful to newbies.. I think it's a Crossfire tradition! So go ahead with MP.. you'll get more action (and more in-game help) that way.. happy flying!
