On the topic of the x-ray meters; It seriously does nothing, you literally have to be hugging them if you want it to work. Nah, but it sorta helps...just threw thin walls, but you still have to be right next to them.
I use the yak head and the police cap for the agents and tenzin. Call out is nice on the yak head and less blindfire accuracy. The police cap is kind of useless -15 sound made and +15 slower regen. It aesthetic though which is why I use it. I still think we would be better off with just hats without any stats. It's really noticable on the police cap it takes forever to get your health back. By the way do the stats on the new items actually work on hardcore probably not ey?
