A clean-room reimplementation of DICE's Refractor 2 engine (Battlefield 2, 2005) in C++20. An engine, not a game: it ships no content and reads your own installed copy.

Could you build this?
No Clean-room reimplementation of a proprietary commercial game engine requires extensive reverse-engineering of binary formats, custom physics, rendering pipelines, and networking.
What it would actually take: The project requires C++20, modern rendering backends (Vulkan or DirectX), audio engines, and custom network transport. The hardest challenges are reverse-engineering proprietary binary file formats (con, rfa, mesh, animation) and disassembling game logic using tools like Ghidra/IDA Pro to reproduce exact Refractor 2 physics and lockstep multiplayer netcode. This demands specialized game engine architects and binary reverse engineers.
