I'm kind of new to the game and has been grinding my ass off to get some unlocked weapons. I have unlocked the Xeon and the m.2187 on online multiplayer. I only wanted to unlock all of them to make sure once my Xbox gold has ran out, I won't be able to play with them on local play. So I checked on local play is see if the m.2187 is unlocked, and yet, it says it is locked and to unlock is via challenge and whatever. I saw that I have unlocked the Xeon on multiplayer but it doesn't show up on local play either. Do I need to do those weapon scanning things? Or is this some bug?
