From Press Release:
CD PROJEKT RED has announced a special Winter Holiday event bringing fan-favorite game modes and festive-themed rewards to GWENT: The Witcher Card Game on PC, Android, and iOS.
Celebrations start today and will run until January 5th, 2021. By logging in daily, completing daily quests, and winning games throughout the event players will have the opportunity to earn bonus Meteorite Powder — and then use it to unlock unique, winter-themed ornaments such as cardbacks, borders, avatars, and player titles via the dedicated Reward Book page. What’s more, each week of the event, special game modes including Dual Casting, Plus One, Momentum, and Battle Rush will return for a limited time!
The in-game store has also been updated with unique, time-limited offers. Among these are bundles containing Ultimate Premium Kegs with animated cards from across GWENT’s entire library, even more Meteorite Powder, as well as festive ornaments — including a special Grandfather Frost leader skin for Ardal aep Dahy.
