I can't quite believe it either. Command & Conquer, Red Alert, Command & Conquer Renegade and Command & Conquer Generals (inc. Zero Hour) have their code officially open sourced.

It's great to see these games being preserved for the future even in source code form!
I'm a little puzzled by their README though, which states...
"To use the compiled binaries, you must own the game."
...whereas the GPL V3 license clearly declares otherwise under the Basic Permissions section:
"This License explicitly affirms your unlimited permission to run the unmodified Program."
