Valley of the Winds is the Tenth level in Tolbrynd and features a new hazard called the Tornado.
The objective is to simply clear most of the monuments through the tornado and avoid being destroyed.
Even the strongest and the heaviest machine will be easily knocked down by the tornado. An invertible small machine is recommended while it won't be affected much while falling from height or getting flipped
Unless you're not up to a challenge then an aerial bomber is recommended.
The name Valley Of The Winds may be a reference to Nausicaa of The Valley Of The Winds
