This addon will allow you to replace the gun from Portal 2 with the original model (and sounds!) from Portal 1. Now in a convenient .zip file!
This file is the exact same as the .rar version, but I made it a .zip file, so you don't need WinRAR to use it!
VPK file with Portal 1 model and animations
Script to change the original sounds to the Portal 1 sounds already contained in the files.
How to install:
1. Extract the contents of the .rar (though, if you're reading this, you've probably already done that.)
2. Open portal2_dlc3 (if you don't have it, make it.)
3. Place the .vpk into this file.
4. Put the scripts into this folder.
5. That's all! Open the game and enjoy!
