[quote]He did answer my question well i just wanted to know the credits/points or whatever you gain from doing these missions for the factions are they free to use anywhere or only from that respective faction[/quote] The reputation u earn for a faction is specific to that faction. So u can only use dead orbit rep with dead orbit vendors. Make sense? The only faction marks ive seen have been for vanguard. I could be wrong though. (Crucible marks too)
