Check out my BT-7 tank with custom paint job. It's a standard Soviet WW2 forest camo pattern, but I painted the face of the tank red to make it extra fearsome.
Unlocking new tanks and improving their equipment is just as fun as the actual fighting.
The game has two primary modes: air battles and tank combat. The modes are are separate yet nicely integrated into one neat interface.
Also, there is a hybrid combat that allows you to leave the tank for a few minutes and jump into an airplane to strafe enemy tanks.
However, this hybrid mode allows you to stay in the airplane for only a few minutes. Then you are returned back to your tank. This is presumably to prevent too many players from exiting their armored vehicles and taking to the sky, thus stopping the tank vs. tank battle.
