Just got my "Thank the Maker" medal in a game of assault. Was about to give up for the night as I am having a rough time getting my game going again (not that it was that good to begin with). My daughter is excited too as she was in the game with me.
No cool kills or anything like others here, unless trigger spamming counts.
I have 4 of them in matchmaking and 2 in invasion. Is that a lot? I have no idea when I got them or who I got them against. Still haven't noticed blue flames or haunted helmet. Guess I just don't pay enough attention.
