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).

這意味著 OpenRA 不受原始閉源遊戲技術限制的限制：它包括對現代操作系統和屏幕分辨率（包括 Windows 10、macOS 和大多數 Linux 發行版）的本機支持，而不依賴於仿真或二進制破解，並且具有集成的在線多人遊戲功能。
