Just moments ago I played a round of search and destroy. At the very beginning of the first round, with no person on either team having ANY kills, every single person on the enemy team called in a care package. They did this at the beginning of every round.
They were not very good, but all the free kill streaks were enabling them to start making a comeback towards the end of the game. To top things off, A guy on my team said " forget these guys, I'm freezing everyone's X-box" He then proceeded to shoot his friends riot shield with a specific gun and attachment setup, which in turn froze every ones X-box instantly.
Two awesome new things to look forward to, enjoy.
