Cloud Imperium Games' CEO and creative director Chris Roberts confirmed the news in a press release:
"We’ve been working with Amazon for more than a year, as we have been looking for a technology leader to partner with for the long term future of Star Citizen and Squadron 42. Lumberyard provides ground breaking technology features for online games, including deep back-end cloud integration on AWS and its social component with Twitch that enables us to easily and instantly connect to millions of global gamers. Because we share a common technical vision, it has been a very smooth and easy transition to Lumberyard. In fact, we are excited to announce that our upcoming 2.6 Alpha release for Star Citizen is running on Lumberyard and AWS."
