I know that everyone will agree with me that Portal was one of the best puzzle games ever made, which was a first person puzzle game of Orange Box pack released by Valve at 2007.
A little information about Portal for those who do not know.
Now, here is the biggest news.Portal has been called one of the most innovative games of the decade. A hybrid of FPS style and a new genre of spatial brain teasers, Portal offers hours of totally unique gameplay. Set in the mysterious Aperture Science Laboratories, players must solve physical puzzles and challenges by opening portals, maneuvering objects, and moving themselves through space in ways that used to be impossible.
Playing Portal today will teach you how to love a "companion cube", whether a computer named GLaDOS really wants you dead, and why your friends keep telling you
"The cake is a lie".
