Save and Quit - This is the first 15 minutes of the Portal 2 co-op campaign. This includes the intro video, some of the “how-to” instructions and the first few challenges. There may be a few puzzle solving spoilers in the video, so if you don’t want to know how to beat some of the earlier levels, you probably shouldn’t watch. But if you can’t beat the first couple of puzzles anyway, maybe Portal isn’t the game for you.
*The audio recorded distorted. I’ll try to figure out what happened and re-upload.
