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?

Yes, the progress is automatically saved and synced to the Steam Cloud individually - so when you next join a co-op game it will have stored which levels you have completed. This also means that your progress is shared across any computer you play Portal 2 on.

It's worth noting that progress is never saved during a test chamber though, only upon successful completion.

You will 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 assembly machine as usual.

  • I just completed the last test of a level and it doesn't mark the progress and doesn't let me go to the next. Creating a new game doesn't fix this for me, I'll try to restart Portal 2 and let you know if it does... Commented Apr 19, 2011 at 21:05
  • Restarting the game and completing the test again seemed to have fixed my problem. Commented Apr 19, 2011 at 21:34
  • @TomWij: I did just have some issues when starting a new co-op session - it threw us in the hub but with no progress at all, so it was impossible to do anything. Restarting fixed it so I guess it's just teething issues perhaps?

  • Yes, I guess the server was having problems for a moment in time, hope it doesn't occur more frequent... Commented Apr 19, 2011 at 21:59

If you're doing split-screen co-op on the one computer, then your progress is not saved. Instead, all levels are open to you so you can just go straight to the last level you completed.


No because when I went back on coop portal 2 I started from the begining
