From PAX East has shown a new video showing the gameplay of Portal 2. The video lasts just over four minutes and shows some scenarios in which we move obviously taking advantage of the well-known portals. The voice you hear in the background from the minute 2:13, is also that of a new character in the game: Cave Johnson, president and founder of Aperture Science. Leaving the video in question, we remind you that Portal 2 will arrive on April 21.
