This one is a pain in the ass if you haven't done it already. The requirements:
1. Player one must have completed co-op
2. Player 2 must not have entered a single chamber
3. Players are on each others' friends list
4. Complete the tutorial (calibration) course together
I experienced some kind of a glitch tonight when playing with Kyllian and didn't get it.
Is it possible... that someone here still has not played Portal 2 co-op (and has the game, of course) and wants to help me get this one? I'm sure there are others that need it as well.
