Announcing the card game for iOS with a new trailer, CD Projekt Red confirmed GWENT won’t allow players to share progression with the PS4 and Xbox One versions of the game.
Sharing of progression would work only between the iOS and PC versions, at least, for the time being. On the announcement post, CDPR writes, “GWENT on iOS combines the full feature set of the PC version with controls reimagined for the touch interface. Progress and purchases are shared between iOS and PC (using GOG account), so players can easily switch platforms anytime. Note that Xbox One and PS4 progress cannot be carried over and/or shared.”
GWENT for iOS would be out on the App Store on October 29. You can pre-order the game right now.
