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.

	REALITIC GUNSHOT SOUND MOD Version:1.0  Saxon + GlitchyJoe  10.02.2018  4,357 MB  1173

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

Return to Castle Wolfenstein Singleplayer CoOp 0.9.3 - The list looks small, but the amount of change code is huge. I hope this makes it more stable than before, have fun!

Download the files. Extract them somewhere (NOT in the rtcw folder). Copy the RTCW pk3's (mp, sp and pak0) into the rtcwcoop main folder and start the rtcwcoop executable.

New features:
- Total new client/server network code, its a straight port from rtcwmp which is proven to be a lot more stable than what we currently had
- Working pk3 autodownloading, thanks to the rtcwmp client server code
- Knife throwing (yay!)
- New sound code
- added a new alias for the mp_quickmessage cmd: voicechat

Fixes:
- 'attempts' in end level stats now shows the number of deaths of all players
- if no more lives left wait a few seconds before restarting the map
- new votesounds
- tomb and escape1 one have fixed mapscripts, bugs should be gone
- cvar security fixes, same for autodownload exploits

Return to Castle Wolfenstein Singleplayer CoOp 0.9.3 - Die Änderungsliste sieht zwar klein aus, aber das Ausmaß an Codeänderungen ist sehr groß. Ich hoffe, das macht es stabiler als zuvor. Viel Spaß!

Downloade die Dateien. Entpacke es irgendwo hin (NICHT in den RTCW Ordner). Kopiere deine RTCW-pk3´s (mp, sp und pak0) in den rtcwcoop Hauptordner und starte die rtcwcoop.exe
