Spartan Dawn Squadron ready to kick your ass...
Hi, First of all I want you guys to know that I dont naturally speak english so I might be wrong in the name of the achivement, here its called "Frenesi Asesino" and its the one of getting 10 kills without dying in a Classified match at matchmaking.
My problem is that I have got that medal like 5 times on different classified lists like lone wolves and some others but I've never recieved the achivement, I even have a video or two of me making the medal but I still have it locked.
I wonder if any of you has experienced a problem like this, If so could you tell me what can I do to unlock my achivement?
