OpenRA – Upgraded Red Alert, Command & Conquer, Dune 2000 trilogy

What is OpenRA?

OpenRA is an open-source project that rebuilt and modernizes classic real-time strategy games such as Red Alert, Command & Conquer, and Dune 2000.

They developed a flexible game engine (OpenRA engine) that provides a common platform for rebuilding and reimagining classic 2D and 2.5D RTS games. The OpenRA engine is not technically limited by the original game. It includes native support for modern operating systems such as Windows 10, macOS, and Linux, and screen resolutions, without relying on emulation or hacking, as well as integrated online multiplayer.

Games built using the OpenRA engine are called “mods.” The OpenRA development team maintains three official mods that can be downloaded from this site, but many more are developed and maintained by the OpenRA community.
