Mocha Conquer is a mod for Vanilla Conquer aimed at adding new features to the first generation C&C engine.
Binary releases of the latest commit are available from here, which is updated whenever new code is merged into the main branch.
See Vanilla Conquer's build instructions. Despite the rebranding, the VANILLATD and VANILLARA constants are still used. The rebranding is only to prevent people from bothering The Assembly Armada over Mocha Conquer and to allow running Vanilla Conquer and Mocha Conquer side-by-side.
