Apple Arcade is set to launch this fall with over 100 new, exclusive games and the company has made the notable hire of Nat Brown, an Xbox co-creator and former Valve engineer before the game service arrives.

Reported by Variety, Nat Brown shared the news on Twitter that he started his new role at Apple this week.

After his time at Microsoft and co-creating the Xbox, Brown has held a number of positions in the tech industry including VP of technology at Myspace. But most recently, he was working on Valve’s VR team.

Brown shared that a theme throughout his career has been an “obsession with platform ecosystems and systems engineering.” While he didn’t share exactly what he’ll be working on in his new role at Apple, it could include projects like Apple Arcade, ARKit, and maybe even Apple’s rumored AR glasses/headset that has been predicted to launch as soon as next year.

Brown elaborated about improving games and AR/VR and how it impacts platforms. Notably, Apple Arcade will be available on iOS, iPadOS, macOS, and tvOS.
