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.

Hello everyone. A few days ago, OSJC and NightBerkut released some custom texture mods for Rtcw SP!

OSJCs rtcw sleeves/hands skins pack 2. 2015
to get working simply copy the desired uniform pattern .pk3 files into your 'main' folder and you're good to go.
some remixes of the 'arms' to include more than the standard 'ranger' uniform skin and to increase resolution...
this is an ammendment of my previous work to add in what was I felt was missing:
each uniform skin now includes a gloveless hand with the apprpriate matching sleeve (so the pistol reloads look less odd) also includes a fix of the sten model to include a sleeve on the arm. plus, each uniform has a matching armour pickup.
I have made some entrely new arm/leg and some new glove skins since and have included these too.

OSJCs rtcw mp40 skin. 2015
to get working simply copy the .pk3 file into your 'main' folder and you're good to go.
this is a combination of the defaiult model with the high res skin (original by teh snake) and the the newer mp40 arm and magazine models with teh snake's skin on the magazine (also sexed up the 9mm in the mag a bit too...)
no offence to any original authors but I felt this looked rather nice, so here it is to share...

Snow Textures by NightBerkut with higher quality. Drop the "z_snowtexture.pk3" file in your "Main" folder.

Please support OSJC and NightBerkut by giving their texture mods a try.
That's all for this update. Thanks for your interest.

RtCW Cooperative - Timegate

This is Yo$hik's release of the classic "Return to Castle Wolfenstein" singleplayer mission, "RtCW Timegate", that he's converted for "Return to Castle Wolfenstein Cooperative Mod". Fighting your way through this mission you'll come up against many familiar foes, but this time you're not alone. Here's what Yo$hik had to say about his new "RtCW Cooperative" adventure:
"You can play with the RtCW Coop autosave spawn option or with the flag zones, (recommended), spawn option.  All trap-doors are removed, all moving platforms will return and they move in a  loop. The cable-car and lifts have a delayed start time, this provides some extra time for players with different pings to connect to the server and not spawn in air :) . Cutscenes are rebuilt and now playable. I've added new, small areas, new secret places, models, music, etc. too. The locomotive now has a longer journey for more fun. I hope you all enjoy this new mission and have a lot of fun playing it. Cheers!" - Yo$hik

Thanks:
Yo$hik would like to thank the following people.
# The creators of the original "RtCW Timegate" mission, Priv and Pbald.
# Tatiana Provorova for all her map testing and help for this release.
