This is the new models made for the Cleaner's Kit add-on, released without the files from the original mod.
If you already have the Case Closed mod installed and just wanted the new models, then this is the file for you!
This archive is just the 'new' weapon models (and the HD pack stuff), without any of the files from the original mod. Well, except the tweaked titles.txt - that's mostly included to help make sure this one is installed correctly.
Valve (original models)
Gearbox (HD models and sounds, and Blue Shift arms)
R1chard (new hand/arm textures)
Taken from the Extended HL HD pack v8.4
* Alexander "your evil twin" Van Wingerden-Cross (for NPC and enemy models)
* Maestro Fénix (Alien Controller model)
* XRGMUser (improved HECU Marines, fixed zombie scientist, improved RPG, PS2 headcrab with OF anims)
...if I've missed anyone, my apologies - it wasn't intentional. Let me know and I'll fix it.
