Bruh, it's crazy.
This is the first CoD I've played since the original Black Ops, and this process of unlocking weapons and attachments has been a bit much, even with at least passing knowledge of how this usually works, and I'm used to frustrating grind, since I'm basic playing this whole on a break from Destiny. I feel AWFUL for anyone who's legit just getting into this series with this game. That wall they're going to run into with having to level up multiple weapons and battle pass levels (they ain't slick with some of them attachments being locked behind BAS-P leveling) is pretty tough.
Thank God for Kill Confirmed games on Shipment.
