Video Game Military Challege Coins(help!)

[jrv312]

Greetings,
I am in need of help finding Video game related Military Challenge coins or rumors of existence. My goal is to have one of the largest collection of Military Challenge coins.
Here is what I have so far (pictures to come).

Common(you can find these on Ebay once in a while)
Rage
Assassins Creed
Batman AC
Skyrim
MW3
Black ops 2

Rare(maybe seen once on Ebay or just on military bases
Homefront
Resident Evil Revelations
Spec ops the Line
Black ops
Battlefield 3

Non Games
Hunger Games
Game of Thrones
Avengers
Honor (do not have, and I am not really looking for it)
Twight (refuse to have in my collection and I do not own one)

Does anyone know of any others in existence?
Sometimes they are really hard to find, example; I have never seen anything about the homefront coin.
Most of these are very rare and are only given away at Military installations and at times I have paid anywhere from $10-$30 each on ebay, or just buying the game on base and you get it free. I thought some of you guys/gals might have an idea.

I will have pictures once I have a chance this weekend.

Thanks a ton
