OpenKingdoms: reconstructing the Total Annihilation: Kingdoms engine

OpenKingdoms reimplements the Total Annihilation: Kingdoms engine in C11 from observed game behavior. Its native and WebAssembly builds load the user's game files and reconstruct economy, combat, AI, animation, mission scripts, and map handling; the repository also records behavior and parity research.
