Discription:
Portal puts you in the boots of test subject Chell, armed with the Aperture Science Handheld Portal Device. Place two linked portals on any surface and step through one to emerge from the other. Simple at first, increasingly mind-bending as you go. An AI called GLaDOS watches your every move with unsettling cheerfulness. Short, brilliant, and unlike anything else. Place your first portal — let’s start testing.
