Some things I noted from the gameplay:

-Littlebird miniguns look and sound amazing, and I bet at night the tracers will be even more incredible.

-Looks like rockets regenerate one by one, instead of all at once, but they regenerate immediately once you stop firing. An interesting compromise with infinite ammo.

-30mm cannon on the attack helicopters no longer has a magazine, but uses the same overheat system as the Littlebird guns, and it overheats quickly. Again, another interesting compromise.

-Attack heli used ″Heavy″ rockets for the pod and started at 10, while littlebird had normal rockets starting at 14. So there's some different load out options already.

-Helicopters looked super maneuverable and easy to fly, but didn't seem like they had BF2 style maneuverability where you could barrel roll.

-I couldn't really tell if there was a vehicle-disable system like previous games. One helicopter ate a stinger and lost 65% health and was smoking badly, but controls didn't look compromised.

Overall pretty psyched to fly these as someone who used the shit out of Helicopters in every modern BF game.
