Build your unique flying city

Airborne Empire is a one-of-a-kind Open World RPG City Builder. It challenges players to build, manage, and grow their own unique city in the skies. They traverse a vast and rich open world full of new dangers, exotic wonders, and many hidden treasures. They must manage lift, balance, and propulsion needed for a flying city. Sky pirates can upend the city’s tranquility, and players must defend their inhabitants – and the kingdoms below! – from destructive attacks. Only clever and daring leaders can grow and protect their homes, seek out and destroy enemy strongholds, and finally reunite the peoples of this world.

Research and discover through exploration

While exploring a variety of biomes, players find themselves deep in an open-world full of rich characters, dialogue choices, side-quests, and lost marvels. By helping the peoples below, they gain the knowledge to develop new technologies – including new lift, propulsion, and morale buildings. They’ll also gain access to better tools for defense – and offense – against the pirate threat; defense towers, cannons, and attack planes can be researched, upgraded, and augmented with the tools found by combing the world and unraveling its mysteries. With full systems for building upgrades, fires, sickness, injuries, light, morale, and augmentation relics, there is plenty of treasure to discover!

Reforge a harmonious world

If players can manage the challenges along this adventure, they’ll find themselves the leaders of a sprawling sky city, with enough prowess to defend against any incoming threats. It shall be the capital of a harmonious empire – the Airborne Empire of legend – reforged under their banners.
