OpenRA is a cross-platform open-source re-imagination of real-time strategies Command & Conquer, Red Alert and Dune 2000. It is not their direct clone, as it took gameplay elements from later titles such as Red Alert 2 and Generals, even added new units to Red Alert.

As of 2023, it is actively maintained by the community and designed with modding in mind. As an engine, it has been used as a base for full game releases such as D.O.R.F. Real-Time Strategic Conflict and OpenHV.
