Portal Free on Steam Until September 20th

If you’re one of the 13 people in the world that doesn’t yet own Portal, you’re in luck as the original game is absolutely FREE, until September 20th that is. It’s all part of a “games with learning” initiative from Valve. If you install the game before the 20th it’s yours to keep forever, so get on it now!
