Command & Conquer Source Code

The promised source code for Command & Conquer: Tiberian Dawn and Red Alert are now available on GitHub, offering modders and other hobbyists a look under the hood of these classic real-time strategy games. PCGamesN points the way to a Reddit post explaining more about this:
The mod DLL source code is the legacy game code, but adapted to work as a extention of the Petroglyph GlyphX engine, so some minor bits are missing. But all code for the core game machanics is there, along with all sorts of random legacy code (although unused) for the history hunters out there!
