Welcome to the OpenRA project.

OpenRA is an open-source reimplementation of Westwood's Command & Conquer: Red Alert game engine, updated to use the hardware acceleration of modern video cards using OpenGL and cross-platform positional sound built upon OpenAL. It runs on Windows, Linux and macOS. Feel free to improve upon OpenRA. The development process is public and open to everyone. We are happy to include your patches after a code review.
