As expected, the rumoured Witcher 3 card game Gwent has been announced as a standalone game at E3.
This is the "new type of video game format previously unexplored by the studio" that CD Projekt Red mentioned earlier in the year.
This version of Gwent looks slicker, and has a full multiplayer and single-player mode.
Gwent will launch in closed beta - available first on Xbox One and Windows PC - which will begin September 2016. Gwent will also be released on PS4.
Just like with Hearthstone, you'll be able to play with users on PC, even if you're on a different device. Although whether cross-console play will be included is another matter.
There was a lot of other new game announcements at Xbox's conference, which you can read up on with our E3 schedule guide.
