Return to Castle Wolfenstein is a 2001 first-person shooter developed by Gray Matter Studios and published by Activision, a reboot of the Wolfenstein series. neortcw is a Return to Castle Wolfenstein source port based on iortcw and ioq3, aiming for a smoother experience for players and developers. It uses a unified CMake build producing singleplayer, multiplayer and Enemy Territory binaries for Windows, Linux and macOS, and is actively developed.
How it differs from the original
Compared with upstream iortcw it raises the server tick rate, adds client-side prediction for some events, replaces OSP-style antilag with a Valve-style approach that is on by default, auto-detects widescreen and uses higher default visual settings. Enemy Territory can also be built for WebAssembly as a browser client with a Node.js dedicated server.
Getting started
Build from source with CMake 3.12+ and SDL2. If you own the game on Steam, its files are detected automatically; otherwise copy the singleplayer or multiplayer data files from your RTCW installation into the main folder next to the binaries, then run the singleplayer or multiplayer executable.
