Hei!
I completed a CTF game without dieing, and I had 18 kills, but i didnt get the Perfection medal. It happened 3 times since I started playing halo 4, but this round was even more annoying, since it said I had 2 killing sprees and 1 killing frenzy, but not a running riot, however I never died.
I took pictures of this, cause it is hilarious.
Score - 280
Kills - 18
Assist -2
death - 0
K/D spread - 18
Spree - 13
Medals - 35
WTF?
Why I never get the perfection when I complete the games without death?
