Hey all, I played singelplayer in coop with someone. And no I did not recreate one map and made a picture form that map,I made a vid to prove its possible.

edit:
There are still some bugs, like invis walls toggling when the other went through.

DOWNLOAD AND HOW TO DO IT!!
Ok, I couldn't find the original link anymore (where I downloaded it), I didn't create the pack.
But I made some changes, also its much easier now to do it. I created a script which does all the work for ya, for the people who don't know how stuff works.

Download this, extract the folder "maps" and "cfg" to steamapps/common/portal2/portal 2/
Overwrite when it asks, dont worry , It does replace comentary though.
But just verify ur cache and it will all be back .

How to start
Only one of you (the blue player) needs to have this installed.
Just play with your friend or online, but its important that the one who installed this pack is the blue player.

Once you are in the hub, the blue player needs to enter this command in concole: exec sp
When you want to play normal coop maps again, the blue player needs to restart his portal 2.

Credits go to the original creators, I just modified some things and made it easier to use.

Also, admin, I think I pressed the report button (its right next to the edit button, way to close!)
