I have been playing BF4 and every now and then I come across these players with these cool-looking, white, complex dogtags, nothing like the usual. These tags have a barcode looking thing on them, and they seem to have a sphere shaped thing as the background picture. This tag looks more like a keycard, to be honest. I don't think it's anything to do with the Phantom project, as I have completed that.
I really want it, but don't know how to get it. Please help.
