32 Player Mod Fixed Again

Hey before you read the rest of this page if your interested in playing portal 2 multiplayer with more then 2 players again cause the old mod made by guyman445 broke then please check out our steam page for it
(side note: the 32 player mod above doesn't officially support any of my mods sure it will work but just be ready to use noclip if you need it)

Change Log

-Modified the co-op lobby to make it easier to load into the game

-Fixed a glitch where GaladOS wouldn't talk (for a 5th time it feels like this glitch will never be fixed)

-Added a ReadMe.txt

How To Install

Step 1 Download the files here


Step 2 Right click Portal 2 at the left side and click "Manage" then click "Browse Local Files"

Step 3 Open the file you downloaded and drag the folders named portal2_dlc3 and portal2 into the
Portal 2 folder you just opened by clicking "Browse Local Files" (make sure you do NOT drag it into
a folder inside of the "portal2" folder just drag it into blank space or some file that is not a folder
or the top bar that says "Portal 2" its hard to explain just look at the gif alright)

Help I Cant Hear Dialogue!!!

[I THINK I fixed this but im not sure if you do have this problem (While using the latest version) please comment]

How to fix:

Step 1 Go to the games main menu
Step 2 Open the console with the (~) key
Step 3 Type snd_rebuildaudiocache [THIS WILL FREEZE YOUR COMPUTER UNTIL ITS DONE]
Step 4 Wait for the bar to become orange or the game to crash (If it doesnt crash tap the (~) key to open the console then type "quit")
Step 5 Go into a Portal 1 map in multiplayer
Step 6 Open the console and once again type snd_rebuildaudiocache

Once you do that your sound should be permanently fixed
