OpenRA is a project that recreates and modernizes the classic Command & Conquer real time strategy games. We have developed a flexible open source game engine (the OpenRA engine) that provides a common platform for rebuilding and reimagining classic 2D and 2.5D RTS games (the OpenRA mods).

意味住OpenRA不受原始閉源遊戲技術限制嘅限制：它包括對現代操作系統和屏幕分辨率（包括Windows 10，macOS同大多數Linux發行版）嘅本機支持，而唔依賴於仿真或二進制黑客，並具有集成嘅在線多人遊戲功能。
