This is the real gunshot mod for Return to Castle Wolfenstein, created by Saxon, which has been fixed and updated by GlitchyJoe from ModDB. Here's what he had to say about this update:
Saxon's (all credit to him) mod was incorrectly made and not maintained. He must have used a 7zip file and renamed the extention to .pk3 from .7z This is incorrect. You must take an existing .pk3 file, empty it and then mod it's insides as you desire or simply rename a zip file to pk3.

About the Mod: Real weapon sounds pack for Return to Castle Wolfenstein. The audio in this pack replaces most of the default weapon sounds for RtCW, including the default reload sounds.
Weapon sounds included are: Colt 1911, FG42, M1 Carbine silenced Snooper Rifle, Luger P08, Mauser K98 (yeah I know, technically the in-game model is a Garand but whatever),  MG42, MP40, Silenced Sten, Thompson, Venom (sounds were pulled from an MG42, because this gun is fake)

I've also included some proper German voices which are unused sounds from Condition Zero. It's kind of nice to hear proper German in-game! Sadly I haven't been able to replace the scripted voices.

Please do not re-use these sounds without permission.

Installation: Just place the .pk3 file in the main folder of Return to Castle Wolfenstein.

Return to Castle Wolfenstein - ioRtCW version 1.51c

This is a small maintenance release, mainly to address a couple of crash and potential security issues for the "ioRtCW" engine, the libraries for sound/video/input have also been updated.

Here's some screenshots of "ioRtCW", with an added HD texture pack. The results are excellent.
It doesn't matter if you use a Linux, Mac or Windows operating system, there's a version of "ioRtCW" available for you to use. Download the appropriate version of "ioRtCW" that you need for you operating system, install it and enjoy a very up-to-date version of our beloved "Return to Castle Wolfenstein".

Return to Castle Wolfenstein Singleplayer Venom Mod by HEllBaron89

The goal of this little modification is increase the general feeling of the game with a more aggressive and modern IA of enemies and the best graphic possible for the original game, with HD texture for some weapons and enemies.

Installation:
Copy all the content of the package like it's on your RTCW installation folder. The cfg. file is facoltative, but increase the graphic quality to max possible for the engine. (is necessary the game patched to 1.41 to apply the wide patch and extreme quality cfg file!!)
