Hazel has chromed up some custom Killzone and Gears of War minifigures featuring said accessories. Firestar Toys seems to be exclusive on this right now, and as I mentioned, quantities are limited.
But wait, there's more! Firestar will also have these Killzone tactical vests designed by ORRANGE. Pedro's United Armory is scheduled to have them in the US soon.
I'm hoping to have more on Firestar Toys soon, as they have quite the operation out of the UK. Not in the UK? Fear not citizen, they ship internationally too! Check out their site for details.
