Well I was just playing online, and after I reached level 3 for my online rank, I hit the xbox guide button to see how many points I had and it gave me the achievements for winning all full auto medals and for a five in a row.......I havent completed either yet. The last campaign series i completed was the Ambush series. Has this happen to anyone else....check out my gamercard page to see the proof.
also I went from a 3 star rep to a full five in the process....
