Some source code files for the first Command & Conquer entry, later called Tiberian Dawn, and the original Red Alert have been available since EA released remastered versions of the two games in 2020.

Combined Arms is a massive fan project built on the source code of the original Command & Conquer with enough content to be a new game in its own right.

The whole Command and Conquer series is revitalized as EA launches Steam mod support, alongside source code for Red Alert and Tiberian Dawn.
