There are a few liberties taken that I will take care of as I go on, and is absolutely not complete as there are still tons of sounds left to go. This is really old and originally a personal pack.
Notably, this mod enables some tabbed out voice lines for the turrets. I assume this was because these lines are more corporate centric and less """"innocent"""", but having heard this turrets speak the same lines over and over, I don't think anyone would mind the variety.
NOTE: This will probably not work, I'm trying to figure out a better solution
To use this mod, first download the base mod here, then download this mod. Put the base mod in hl2/custom (If there is no custom folder, create one), and edit portal's gameinfo.txt.
In the brackets of SearchPaths, under "game+mod portal/custom/*", copy that line below and edit that new line to point to the base mod. So in my case, the base mod is located in a seperate game - "portal/custom/*" would be "../Half-Life 2/hl2/custom/*" (It actually points to every mod in the custom folder, but contains the base mod's vpks. You can specify if you want).
Make sure this new line is under the original line, and any before it so it takes the least priority. This is to ensure that the base mod doesn't overwrite your other sound or script mods.
