Complex SKY — start building a futuristic city of the future. Now you have to build in the sky, and this opens up a bunch of new possibilities for you. For example, what is worth the ability to build not only up or to the sides, but also down. Your city will be in front of you in three-dimensional space, you can rotate it and inspect it from all sides, and this, in turn, will allow you to personally design everything to the smallest detail, every single detail. You will construct buildings in the skies, you will be able to erect complex projects, erect industrial buildings, design infrastructure and much more. But first of all, you will need to take care that the city can become autonomous and independent.
