COMPLEX SKY is a futuristic city building game with a unique architecture system - build the city both ways, up and down! The world is devastated by pollution, and it’s up to you to create a fully self-sustainable city in the skies, and populate it with human settlers.



Create a world, unrestricted by gravity. Unite buildings into wondrous formations, gather resources, create production chains and develop the world’s ecosystems - all to build a fully automated, self-sustainable city among the skies.

Created by a solo developer, COMPLEX SKY is a genre-blending mix of city-building gameplay with puzzle and strategy elements.



Build beautiful, gravity-defying landscapes: Stack structures on top of each other and create a city unlike any other! The city is your oyster: create your own style!



Once you run out of space, flip the whole city upside down and continue building, using the game’s unique vertical architecture system. Keep your city running by supplying buildings with water and electricity. Time to put your engineer hard hat on!



Choose a tech corporation to headline the Complex SKY project - each with their own traits, advantages and drawbacks. Keep the perfect balance between the well-being of your citizens and industrial might and utilize all the perks of your corporation to the max.



Scientists, Workers and Operators will populate your Utopia, and their well-being is key to the prosperity of your city. Fulfill their needs and get access to advanced technology and building schematics. Create your own technocratic paradise!



Set up supply chains, and grow and optimize them to ensure the steady growth of your city. Start by mining rock and coal and progress to developing experimental composite materials.



Choose from a story-based CHALLENGE mode and a free-range SANDBOX. Want to test your skills further? Spice it up with the custom difficulty setting and see how far you can get in an unforgiving environment.



Complex SKY is presented in a strikingly minimalistic art style,which is further enhanced by a playful, upbeat soundtrack.
