There are 2 new vehicles i noticed in the new trailer. I will go over all the vehicles shown.
First vehicle we saw was a personal tank, ive never seen this exept in screenshots. One thing i noticed about this is a guy jumps out of it from the back. So this might be where you get in/out probably with a certain key on the keyboard.
Next we saw the plane. We have all seen this, so really nothing new. THere are no weapons (exept for the plane itself, which was used to kill people a number of times in the video) so we know this is strictly for transportation.
This Truck/car is in the middle of the video when showing the neutral zones, it is shown driving by on the road. Not much other than that, maybe just for transportation.
and the motorcycle thing, nothing new. Definatly just for transportation seems fast and agile.
