Geez, how long has it been since I last been on Scratch? So if your wondering why a topic like this is here in 2017, well as of making this, I just loaded up Portal 2 for the first time. Not expecting this. No, the Portal 2 intro wasn't this you have here, this is just a little Scratch thing I made after having seen it. And to explain what is going on in case you can't understand, this is suppose to be what it looks like when you load Portal 2 on steam. Now before with Valve games, they had this guy as their intro, but however it was a still image of him not looking at the camera. Since that version is in most Valve games, ya tend to get used to it. But, in 2012, valve released an update to Portal 2, replacing the other version of the intro I just described with this. Needless say, it caught some people off guard when an image they constantly see suddenly moves. If you want to see the full version, here's a video showing the previous intro and the this one: https://www.youtube.com/watch?v=Us38lQFFTug
