We have shut down the GeForce NOW store on SHIELD. The new GeForce NOW free beta lets you play your PC games from popular digital stores such as Steam and Uplay.
All users should receive an email from NVIDIA with digital store keys for games they have purchased. We have added support for most of the top games from the GeForce NOW store to be available on the new GeForce NOW. Simply redeem your game code and play them on SHIELD.
Please note Witcher 3 on GoG is currently not supported; we are working at adding this in a future software release
