Steam Workshop


Airport CEO has Steam Workshop support! Head over to the Steam Workshop portal and discover other CEO’s airports, new businesses and airlines.

Note that you have to own the game and be logged into Steam to properly view the Workshop.




We believe that user generated content is what makes a game and its community really thrive. As Airport CEO develops from an early access title to a full game, we will gradually convert game components to become modifiable. While this implementation roadmap is not set in stone the general idea is that, from a development and technical perspective, the less complex a game component is the earlier it will become modifiable.

Airport CEO has already in this early development stage modifiable components and this is the place for you to read more and learn about how to successfully implement yours or others’ creations into the game.
