Odaily News OKX Ventures announced the completion of a strategic investment in Nytro Lab, the developer of the Castile project. Nytro Lab not only innovates the "Play and Trade" business model, attracting gold-farming players with its curious Cthulhu game style, but also allows for the upgrade and flexible trading of equipment and props required for different terrains such as dungeons, creating long-term positive and sustainable digital asset returns for players. Nytro once won the first place in the same category in the North American Tiktok buying test. Castile has been open for public testing at 20:00 on September 10, Beijing time. The two highly social dungeon experiences, the Leader Alliance Assault and the Elite Tournament will be open for a limited time. The story background presented by Castile is based on the next generation of Magic Cthulhu, AAA RPG card + MMO + Roguelike (similar to the Japanese top game Saima Musume) style. The performance of its heroes and realistic aesthetics, the game NFT equipment and krypton gold card drawing experience add narrative to the web3 game. The 90% player retention rate in previous tests shows the community's recognition of the game.
