I agree, I think the arctic battle rifle is one of the better looking weapon skins. TC the light rifle skin, is only available through the console exclusive edition to the game. The Unicorn helmet DLC that currently sells for 80$ on ebay.
You liked how they had a 45 dollar weapon skin pack for sell? I know you could buy them individually, but don't you think they were a bit over priced. Some of them looked like they were made in under 5 minutes.
