Do they have In-Game Avatar Awards ?

I was wondering if you can unlock an avatar award for completing something in halo 4 ?

and i dont mean the things you can get for your avatar with limited edition and so on…

yes but not sure if it counts as leaks so I wont say what

yup just google it…

Yep. It includes

Knight Helmet:
Unlock the “Knight in White Assassination” achievement to earn this award.
Platinum Mark VI Helmet:
Unlock the “Wake Up, John” achievement to earn this award.
UNSC Infinity Hoodie:
Unlock the “Not Some Recruit Anymore” achievement to earn this award.

I’m glad they do. I feel like AA are a nice little feature that could be used more.
