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.

Castle Gothicstein - Return To Castle Wolfenstein mod released! Original mod and idea by Duchovicius aka VVitchaven.

The Third Reich we know never existed. In 1936 Adolf Hitler faced huge riot in his country. Germany was divided into two parts: Nazis and Teutons. After two years of civil war Teutonic Legions led by Erhard Schreck managed to reach union with nazi Germany...
hide detail - Castle Gothicstein is the updated version of vanilla Castle Gothicstein. This is the hardcore trip into the dark sence of alternative world war 2. Prepare to the biggest challenge sinse your first play of RtCW.

Important:
This is the not final version, later we planned to add more stuff to this. Please don't use any other texture mod mixing with that. If you have the texture bug (it's not non-colored for example), you may use the WinRAR program to open the zzzz_gothic.pk3 file and search for needed texture. When you found it, make .tga copy of texture and put copy to same folder. If do everything right, all will be okay. We really sorry with artefacts in escape1 and escape2 levels. But this is only one way to make right lighting. Perhaps we'll make fixed versions of this levels compiled in Q3map. We hope on your feedback and let us know if something wrong.

Key developers:
- Yo$hik - levels, lighting, scripting, design, shaders, AI, idea
- AidenDemon - level design, AI, music directon, textures, idea
- HellBaron89 - weapon shaders

Known features:
New textures and shaders,    New models and skins,    New sounds and music,     New story,     Adwanced AI

This is a Return to Castle Wolfenstein Single-player, two-map mission that has been converted for Return to Castle Wolfenstein Cooperative Mod by {WeB}*GANG$TA* of the Wolfenstein European Brigade Clan.

Storyline Part One
You must attack and gain entry into the formidable Wolfkrieg Castle. It is a heavily defended Wehrmacht communication center where the German High Command have drawn up their battle plans to repel the Allied advance.
They intend to transmit those plans to the German front lines as soon as possible but, fortunately for Allied Command, poor weather conditions are hampering their efforts.

Your Mission:
# Destroy all alarm systems to prevent German reinforcements being alerted.
# Kill all German officers that you find there.
# Steal the first copy of their battle plans
# Find any secret areas
# Make your way to the next part of Wolfkrieg Castle

Storyline Part Two
You are now deep inside Wolfkrieg Castle, elements of Helga Von Bulow's Elite Guard are searching for you, as is a detachment of the deadly Blackguard paratroopers. Be alert at all times, they will not stop hunting for you.
Be warned, there are civilians in this part of the castle, if you kill them your mission is doomed to failure.

Your Mission:
# Find the second copy of the battle plans
# Kill all German officers
# Find any secret areas
# Destroy as many of the enemy forces as you can and escape

Map Convertion Story
This is what {WeB}*GANG$TA* had to say about the map:
"I never made any part of these maps, I merely converted them to RtCW Cooperative Mod. All I could find out about the maps' origins is that they are about 10 years old and had several names, such as, "Enemy Castle", "Nightmare Castle" and "Return to Castle Wolfenstein 2".
The maps were created by Vladimir and Andrey, again, that's all I know about them, their emails do not feature in the map "read me" file. These maps are marvelous and deserve to be played far more often than they are as RtCW SP missions. Hopefully my conversion of them will achieve that very thing." - {WeB}*GANG$TA*

Thanks to
{WeB}*GANG$TA* would like to thank the following people:
# Vladimir and Andrey for creating these excellent maps
# Fretn and his very talented RtCW Cooperative Crew
# SSF Sage for his excellent RtCW Coop Conversion tutorial
# Masahari, {WeB}*Kariboe*, {WeB}*Coisty* and {WeB}*DOG* for all their help, encouragement and testing of the maps and also for all their support of the superb Return to Castle Wolfenstein Cooperative Mod
