This addon for SCP - Containment breach aims to overhaul the sound effects you hear in game. Enjoy!
When you download the ZIP and unpack it, you will see two files, one of them is a manual installation and the other is an easy installation. The manual installation is there so you can pick and choose which sounds you want to keep and which sounds you want to throw out. The easy installation is there so you can install all the sounds with little to no effort.
The instructions to each install are included in the files.
