Check out this Portal 2 walkthrough and find the first three vitrified doors with this online demo.


The incidents that may occur in the course of your science adventure. Your test assignment will vary depending on the manner in which you have bent the world to your will. Those of you helping us test the repulsion shell today, just follow the blue line on the floor. Those of you who volunteered to be injected with praying mantis DNA, I've got some good news and some bad news. The bad news is we're postponing those tests indefinitely. Good news is we've got a much better test for you, fighting an army of mantis men. Pick up a rifle and follow the yellow line. You'll know when the test starts.

Just a heads up, we're going to have a superconductor turned up full blast and pointed at you for the duration of this next test. I'll be honest, we're throwing science at the wall here to see what sticks, no idea what it will do. Probably nothing. Best case scenario, you might get some superpowers. Worst case, some tumors, which we'll cut out. If you need to go to the bathroom after this next series of tests, please let a test associate know because in all likelihood, whatever comes out of you is going to be coal. Only temporary so do not worry. If it persists for a week though, start worrying and come see us because that's not supposed to happen. If you've cut yourself at all in the course of these tests, you might have noticed that your blood is pure gasoline. That's normal. We've been shooting you with an invisible laser that's supposed to turn blood into gasoline so all that means is it's working.
