A Couple questions I have.

So I have a couple questions and was just wondering if anyone could help me out with some answers.

Question 1: Is the Sad Face emblem in Halo 4?

Question 2: How much armor and stuff is there really available to unlock. For some reason I have a feeling there isn’t a lot and it wont take long to obtain all of it.

Question 3: Weapon skins; aside from the ones you get if you preorder the game, are there any other weapon skins you can get from Weapon Commendations or no?
