I was just reading the Final Hours of Portal 2 and got vet much involved in it. I was very amazed by the first design Valve had for this game and that had no portals but rather a new gameplay called F-SPOT . I was just looking around for something on this but that remains unexplained because apparently Valve is still going to use it in another game although. But this thought should definitely came in my mind wherein whether we can play Portal 2 be played without portals.Please do get back to me on this.
