How can you tell if you've already completed a level in the co-op part of Portal 2? I thought it might be the bars (blue/orange), but I'm not sure.

When you go into the entrance for a co-op zone, there will be a little bar graph and lights for each player (blue and orange) that show which of the maps they have completed.

    You can look either inside the room, at the monitor with big red buttons, or you can look at the display right above the course door. Commented May 30, 2011 at 3:45
