RealRTCW

RealRTCW is a community-driven single-player overhaul for Return to Castle Wolfenstein, built on top of the original iortcw and rtcw-sp source code.

The project focuses on modernizing the engine, expanding gameplay systems, and improving overall stability and quality of life—while staying true to the original RTCW experience.
