How to buy games on Meta Quest 2
The Quest 2 has a built-in store that you can access in VR, so you can buy games, download them, and jump straight into the action without ever taking off your headset.
The mobile app includes the same store, allowing you to browse Quest 2 games at your leisure when you're not in VR, make purchases, and queue games for download.
If you purchase a Quest 2 game through the mobile app store, it will download the next time you turn on your headset and connect to the internet.
