Roco Kingdom officially locked in its upcoming cross-platform Quack Quack Closed Beta test for October 27, 2026, alongside releasing an action-packed Strategic Battles trailer showcasing competitive Jinie combat across PC, consoles, and mobile devices. According to verified reports from IGN India, developer Tencent Games and its subsidiary studio are expanding the creature-collecting open-world RPG across Steam, Epic Games Store, Windows PC, Xbox Series X/S, PlayStation 5, iOS, and Android. The fresh gameplay footage demonstrates expansive open-world exploration paired with turn-based tactical monster duels, where players recruit mystical spirits known as Jinies to execute complex ability chains. The title invites direct comparisons to major genre contemporaries while carving its own identity through fast-paced party-switching dynamics and synchronized co-op encounters, much like modern multiplayer raids covered in our [Aion 2 Deus Research Base: Boss Guide and Loot [Full Guide]](/news/aion-2-deus-research-base-guide). Prospective tamers can immediately wishlist Roco Kingdom on Steam ahead of the October testing phase, which will stress-test cross-platform netcode, balance early-game Jinie species, and gauge competitive balance across global test clusters.
