We are extremely happy to announce that Airport CEO 1.0 has been released and consequently left early access. After three and a half years of early access development, Airport CEO has matured into a complete and stable 1.0 game. We've tried to summarize our thoughts in the 160th dev blog, published on Steam as part of the 1.0 release announcement message.
Celebrating this 1.0 release, we're also releasing a an aircraft pack as a micro DLC, Airport CEO: Supersonic! You can read all about it here on the DLC page!
