Might as well give it a shot - Portal 2: The Second One!

Might as well give it a shot - Portal 2: The Second One! is a livestream.
==Video Overview==
Kurt as he always does starts off by talking to the chat about Portal 2, how he played the original years and years ago but only watched Let's Plays of the second game. After giving tips about butcher counters, Kurt loads up the game. He wakes up in an unknown room as part of a subject of a study getting monitored, but the second time he wakes up it is dilapidated. A silly AI named Wheatley wakes him up and helps him escape as his room is destroyed. In the first room, Kurt notice drawings of his character Chell, and is informed to read a comic. Kurt is introduced to game mechanics with cubes and portals in abandoned but functional chambers. After having helped Wheatley, Kurt awakens GLaDOS, a very snarky AI who remembers Chell killing her and forces her into more test chambers. Kurt manages to do quite well with the early puzzles, and gets glimpses of Wheatley. Kurt is introduced to turrets and how to utilize them to his advantage. After dealing with more and more turrets, Kurt goes on break.
He returns and talks about how he is not feeling that great with playing the game, but it is probably that he's seen Let's Plays. The next section introduces light bridges and laser cubes, and Kurt keeps going with his quick puzzle solving skills. He finds some offices of the old Aperture facilities, as GLaDOS pushes him along before Wheatley manages to break him out. Kurt sees where turrets are made and recycled, and then is placed into a fight with GLaDOS. Kurt presses the button to kill her and Wheatley promptly betrays him, throwing GLaDOS AI into a potato and tossing them both down a massive pit. Looking around a bit more, Kurt goes on break.
The area seems to be the original testing area of the facility, long covered by newer innovations. Kurt is introduced to repulsion gel, and hears voice recordings about the gel's development from Cave Johnson, former CEO of Aperture. He uses the repulsion gel to bounce around the old area as Johnson says a lot of very amusing dialogue about testing procedures. Kurt finds Johnson's office, and retrieves the potato with GLaDOS wried into it. Finding orange slip gel, Kurt uses it and decides to end the stream with Car on a Stick.
