Portal is one of the 5 games that comes in "The Orange Box" compliation or can be bought seperately through "Steampowered.com" This is definitely one of most innovative games to be released recently. The whole premise of the game is to use a " Aperture Science Handheld Portal Device" that lets you make portals in the wall to get you through a variety of different mind-numbing obstacles. The premise is a little hard to explain in words, but after a little while of playing, you get the general concept and then you can cruise through the fun, inventive levels from there. The gameplay gets an additional boost with a humorous female robot voice who guides you through the game.
My only complaint with this game is that it's too short. The game itself is so fun that you just want to keep playing and playing. I was disappointed when I had finished the last level because I knew that it wsa over.
Remember though, the cake is a lie.
