Scott and I ran through the co-op storyline today. Lots of fun, although we got stuck good and hard twice, once because we simply couldn’t figure out how to combine the available portal surfaces to get the second player across, and the second time because the solution we came up with was so complicated that we knew we had to be overthinking it and missing something simple (“no, that really is how you do it”).
As usual, it was a lot easier with tablespeak than it would have been with any manner of chat session.
Pity they couldn’t come up with a way to work more Cave Johnson dialog into it…
[Update: belatedly, it occurred to me that the people who are claiming they solved the co-op puzzles alone, only needing a partner to satisfy the “both present at the exit” requirement, are full of shit. For some of the puzzles, getting one player to the exit is relatively easy; the actual challenge is getting the second one across. That was the exact situation that stumped us: I made it to the exit, and could no longer create the portals that Scott would need to use the same method; we had to figure out a different path to the top, using both sets of portals.]
