"Today, we’re announcing a change to the title of our upcoming game, which will be known as The Legend of Khiimori moving forward.

This decision reflects the evolving creative direction of the project. As the game has grown, shaped by the in-depth feedback and enthusiasm of our community, so has our vision for what The Legend of Khiimori can become.

As a result, we have reached a mutual agreement with Alias Entertainment to remove the Windstorm brand from the game. We’re excited to expand on our unique setting in 13th century Mongolia and explore the new creative opportunities that this change opens up. The original spirit and core experience of the game will remain the same, but now we can push it even further.

We’re incredibly thankful for the continued support and interest in the project, and we look forward to sharing more as The Legend of Khiimori moves into its next chapter."

The Legend Of Khiimori will launch in Early Access on Steam starting November 4, 2025, with a playable demo being available during Steam Next Fest, kicking off at 10am PT on October 13 and running until October 20.

“The Early Access version includes the core gameplay loop: exploration, survival on horseback, breeding, training, and questing across a decent portion of the open world. Players can already do a large variety of courier deliveries, interact with NPCs, and uncover secrets in a richly detailed environment. While some systems are still in development, the game is stable and offers several hours of engaging content. We’ll be updating regularly with new features, bug fixes, and quality-of-life improvements!”

“We plan that the full version will feature a compelling main story, an expanded open world, more side quests, new areas to explore, as well as refined horse- and survival- mechanics. We also plan to add voice acting, a full localization, improved performance, and deeper environmental storytelling. Player feedback will guide improvements to controls, and overall game balance.”

Start crafting powder pouches and special arrows to survive the dangers of the Mongolian wildlife. Archery is deeply entrenched in Mongolian culture, and it will be yours to master. However, in this game your bow and arrows are tools rather than weapons. Different arrows and powder pouches are used for gathering resources, defending yourself from dangerous wildlife and mindful hunting.

Take on various activities and thrive as a Yam courier rider. You will be tasked with delivering packages and cargo, gathering vital items, and mastering the challenges of the open world. Quests will test your capabilities, requiring the right steed, excellent riding mastery, and thoughtful planning, as well as skillful resource management, useful crafting, and keen archery to survive and succeed. 

The Legend Of Khiimori is coming to PC (Steam) in 2026, with Nintendo Switch 2, PS5 and Xbox Series X|S also planned.
