Take the tour ×  I've started playing the coop campaign of
Portal 2 during launch break today, and had to stop because of
time constraint. I didn't find an option to save the game, so we
just disconnected.  Is there a way to save the coop campaign
progression? If yes, how does it work? Or will I have to play
the whole campaign in a single play session?  share|improve this

be able to pick which level to start at next time you start the
game - if you go to the specific chapter you want to play and
use the buttons until you've selected the level you want, then
go into the as
