Or how about THIS???In Options, under Controls, there is an option to turn on CAMERA WILL FOLLOW VEHICLE TURRET!!
TURN THIS ON!!!
Now, when you move your tank turret to the left, the camera will not be stuck in position looking to the front of your tank, but will move according to the barrel! You'll be looking straight down your barrel at ALL times!!
Personally I think it is ABSOLUTELY essential to have this option turned ON!
When retreating back to base for repairs, you can still shoot at any enemies attacking you. You may even be able to kill them before they kill you.
OPTIONS -> CONTROLS -> LOOK/MOUSE -> CHECK BOX FOR 'LOCK VEHICLE CAMERA TO TURRET'
HAPPY TANK FRAGGIN!
