I have all but two weapons left to find/Unlock in the campaign. I need the RFB, which is not where the guides show it to be. On Xbox, you don't return to the lobby. You head to the roof with VIP'S. So I can not locate this one. The other is the Saiga... Idk if its an unlock for Gold score or a dropped weapon. If anyone knows where these are located please let me know. Once I have these I will have the Recon Achievement.
