Its CMake project builds much of the recovered library code for Windows. DRM and in-app-purchase implementations are outside the project's stated scope, and other build types remain unfinished.",
  "description_zh": "Fusion 重建 Rovio 的跨平台游戏引擎库，主要参照 iPhone 版 Angry Birds Seasons v4.1.0 的可执行文件及其调试信息。CMake 项目可在 Windows 上构建大部分恢复的库代码。DRM 和应用内购买功能的实现不在项目目标范围内，其他构建类型仍未完成。",
