Portal 2 is an awesome, awesome game but I think I found a scenario that even GLaDOS herself would love. As you see from the video below, I am continuing a game that has been autosaved at a point. Usually when you die, you start from the beginning of the level but some levels are more intricate and will give you a checkpoint in the middle of it. Here is one of those points, but given the right circumstances you'll never been able to continue from the ckeckpoint as demonstrated by my multiple deaths. This doesn't detract from the game, but it will teach me to save more often.
