CD Projekt Red released Thronebreaker: The Witcher Tales on iOS, marking the first occasion of the game being available on mobile devices.
CDPR officially launched Thronebreaker on iOS. Considering a good chunk of the game is akin to TCGs, it is rather odd that the game didn't make it to mobile devices sooner.
Anyway, for those unacquainted, Thronebreaker is a mix of an RPG and TCG. It's a singleplayer title so don't worry about having to deal with loot boxes or other microtransactions that are usually found in regular TCGs.
In Thronebreaker, players will take control of Queen Meve of Lyria and Rivia who has to go to war due to the imminent Nilfgaardian invasion. To counter their might, Meve needs to amass an army herself which takes her on the journey the players get to experience.
If you are loosely familiar with The Witcher lore and wondered why people refer to the main character as Geralt of Rivia, it is because he is actually a knight. The one who knighted him was Meve herself.
As for the mobile adaptation, CDPR made specific touch screen controls for this version along with cloud save support which will enable players to continue on mobile where they left off on PC and vice versa.
While Thronebreaker is available on PC, Xbox One, PlayStation 4 and Nintendo Switch, this is the first time it became available on mobile devices. The Android version is not yet available but is planned for release later in 2020.
