On September 11th, OKX Ventures announced the completion of its strategic investment in Nytro Lab, the developer of the Castile project. Nytro Lab not only revolutionized the business model of "Play and Trade", attracting gold players with a curious Cthulhu game style, but also upgraded and flexibly traded equipment and props required for different venues such as dungeons, shaping long-term positive digital asset returns for players. Nytro has won the first place in the same category in the North American TikTok user acquisition through ads test. Castile has been in public beta at 20:00 on September 10th, Beijing time. Two dungeon experiences with great social attributes, the Leader League Assault Tournament and the Elite Tournament will be open for a limited time. The story background presented by Castile is based on the magic Cthulhu next generation, AAA RPG card + MMO + Roguelike (similar to the Japanese head game Sai Niang) style, the performance of its heroes and the realistic aesthetics, the game NFT equipment and around the krypton card draw experience added to the web3 game narrative, the previous test of 90% player retention rate, showing the community's recognition of the game.
