# Call of Duty 2: Big Red One: reconstructing Xbox game code in C++

> Call of Duty 2: Big Red One reconstructs the original Xbox game's code as C++ toward a native Linux and Windows build. Ghidra analysis and function naming support the work; a comparison harness checks rewritten functions against the originals, primarily during gameplay and, for some functions, offline. The author reports 7,067 rewritten functions, while most mission-script functions remain unfinished.
