Here is a free extended demo of Portal.

If you havent seen or played Portal yet.  You are missing out, its not often I say that about a 3 hour (ish) game.

Played it when it was released and its addictive, I hope they release some free level packs

Do not watch this unless you have played the game through.  it is something that should never be spoiled.
