Cloud 9 is an open world, weather simulation in which the player is in control of various elemental forces that control the weather, in the ones that control the clouds such as air pressure, humidity etc... The player flys around the world in a no clip/god mode type fashion, and can place anomalies to change the weather to their liking, such as causing an intense heat wave that will suck up a lot of moisture from the ground which then condenses into clouds that eventually cause a thunderstorm. Ground and terrain destruction is very dynamic and is a large feature of the game, with elements such as huge forest fires, landslides caused by erosion from the forces of wind, tornadoes, storms and lava flows all being possible under certain kinds of conditions. There are human settlements that grow as time goes on, and the player may wish to destroy them with weather forces or simply leave them in peace.
