War Wings is a very engaging game, so we want the players to feel as comfortable as possible. Because of this, several types of controllers are available for you to choose from.
The game offers gyroscope, virtual stick, as well as gamepad control. You can try other control schemes to see which one fits you better. And you can also invert Y axis (push down=nose up, or push down=nose down), in the setting menu which you can call out in the middle of any game, by tapping the setting button on the top left corner of the screen.
