What do you know about the Portal universe
There are lots of portal fans, but not all know some of the backround info.What do you know about Portal,do you even know what portal is? If not there is no point in doing this test.
For example, do you know ho many test subjects are sleeping in Aperture? Or what's hidden inside the Companion Cube? Do the test to see just how much you know.
