Just played a couple rounds of War Pigeons. I thought it was very fun even though I sucked. It's basically Obliteration mode from BF4 except you don't have to plant the pigeon, you have to hold it while a timer counts down while you "write a message." The more still you remain the quicker it counts down, but it always seems to take a long time.
I haven't played enough to know whether the timer resets when the other teams gets ahold of the bird, and how many birds you have to send off for the win.
