CD Projekt Red keeps pushing its Witcher legacy, celebrating The Witcher 3's 13th anniversary with new content while eyeing future titles. Rumors now surface of a free‑to‑play co‑op spin‑off codenamed Sirrius slated for PC and mobile. The title promises shared hunting of monsters in a new multiplayer format for players worldwide in 2027 or 2028 launch.

Unlike previous Witcher titles, players will not assume Geralt's role; instead, they craft their own witcher with ARPG‑style customization and a dedicated skill tree. Combat emphasizes skillful dodging, blocking, parrying, and executions, while Signs, casting, and potion brewing add depth to enhance team dynamics in co‑op sessions and reward players with unique crafting options for special.

The mobile partnership with Scopely hints at a broader strategy; CD Projekt Red noted in a March earnings report that the next collaboration would not debut until at least 2027, possibly 2028 depending on development pace. This delay signals a focus on polish over rushing launch for players who value quality and depth in mobile.

If Sirrius launches as promised, it could reshape the Witcher franchise by opening its world to casual and competitive mobile gamers alike. The free‑to‑play model, combined with deep ARPG mechanics, may attract a new audience while keeping existing fans engaged with familiar lore and combat through co‑op missions and shared quests that reward team effort.
