Also, with the Bunker Breach gamemode and at that desert place, START DIGGING DOWN IMMEDIATELY WHEN YOU START. The map is tiny apparently and SOMEONE will start shooting at you very quickly, guaranteed the moment you bring in reinforcements.
Also, the new anti-air drones are hilarious. At the start of a battle on the north pole map, my drone fires a rocket to the left at an enemy dropship. It blows off the thruster and the aircraft spins 90 degrees and bats the brain off the mountain, killing it instantly.
