Go to your Steam Library. Right-click Rainbow Six Vegas 2 and select Properties.
Go to the Local Files tab and click Browse Local Files.

This will open a window in File Explorer.

Open the KellerGame folder and then Config. This is where you drag and drop the downloaded files once you've unzipped them.

If it asks you to replace files, that means you've done it correctly. Make sure you confirm.

I've copied the link to a pastebin so steam can't block it. If this link goes down, contact me and I'll put it back up again.

I highly recommended to use this mod with Highflex's amazing fov camera mod. I use the lowest option to avoid clipping arms. Link to his guide with mod download here; https://steamproxy.net/sharedfiles/filedetails/?id=1423146825

My mod is a HEAVILY modified verson of ParsleyPlant and AZLAKAL's "The Complete Overhaul" mod posted on Nexus Mods. Link here; https://www.nexusmods.com/rainbowsixvegas2/mods/9?tab=files

Basically I reverted everything back to vanilla except the viewmodels. Very tedious since every weapon had modified damage, accuracy, mag size, etc. I also re-added attachments that the mod authors removed for some reason, while also adding in additional ones.

This probably won't get you in trouble, but for your own safety I would advise you to stay out of Punkbuster enabled servers when using this or any other sort of mod. Good news is I've only seen about 1 of them in the past 4 months. If in doubt just turn off Punkbuster in your game options :)

If you like this mod, share it with your friends that still play this game. If there are any issues with it please let me know and I'll do my best to fix them. Feel free to ask questions below and I'll answer them when I'm available. Peace! :)
