Many of us are excited about the upcoming release of Portal 2. From what we’ve seen it seems to retain the twisted, subtle humour of the original whilst upping the difficulty of the brain-melting puzzles.
From now until April 19th Valve will be releasing teaser videos of Portal 2, just to get you in the mood for the game. Trailer one of four can be found below.
