(adsbygoogle = window.adsbygoogle || []).push({}); This is not really a new thing... hell it kinda came out like the first week the game was out but I wanted to let people know that it's still a viable option to rank up "fast"

1) Have a friend host an open player match... (he doesn't nothing else)

2) Go to Split-Screen, create your game and change your map. ( I prefer either SnD or Headquarters/tac boosting)

3) Add 2nd controller

4) Hover over Start Game and hit O and back out.

5) Hover over Split-Screen and hit Triangle to bring your friend's list up

6) MOST IMPORTANT. Hit X on friend with the open lobby and hover over "Join Session In Progress"

7)Tap X on 1st controller then simultaneously hit X on both controllers

It's take a bit to get used to when you need to mash the X buttons but as long as the game loads and there's no game type under the map you should be good.
I would've made a video but I don't have an HDPVR yet

If you do Headquarters I've found I've been able to rank up twice in the high 30's so if you're smart (like I am :carling then you'd do challenges/pro perks while you're in the headquarters lobby
