Exciting news has emerged about Genshin Impact's upcoming sandbox mode, currently known as Thousand Stars or Miliastra. This innovative addition will revolutionize how players interact with Teyvat by introducing comprehensive user-generated content tools. Players will gain unprecedented creative freedom to design custom adventures, personalize their avatars, and participate in large multiplayer sessions.

Unlike previous additions like the Genius Invokation TCG or Serenitea Pot housing system, Miliastra represents a quantum leap in gameplay possibilities. The mode will function as a standalone sandbox environment, though it cleverly utilizes Genshin Impact's existing assets to minimize additional storage requirements. This strategic approach ensures accessibility while delivering a completely fresh experience.

Character customization reaches new heights in Miliastra, with players able to modify everything from facial features to clothing styles. While initial beta tests focus on female character models, male options will debut with the official launch. The mode introduces a novel gacha system focused exclusively on cosmetic items rather than playable characters, accompanied by a dedicated Battle Pass progression system.

The social dimension of Genshin Impact expands dramatically with Miliastra's lobby system. Players can host public sessions for up to twenty participants or private gatherings with twelve friends. Early footage suggests the interface draws inspiration from Simulanka, the setting of Version 4.8's summer event, potentially connecting the mode to the mysterious character Alice in the game's lore.
