Portal 1 (PC Classic) - Ending, GLaDOS Song... and Cake!

The puzzle-themed first-person shooter, Portal, features the main character Chell, a voiceless female protagonist struggling to stay alive in the cold and mysterious Aperture Science facility. The facility is controlled by a ruthless, yet somehow incredibly charming AI called GLaDOS. As you solve each puzzle, you begin to realize that no progress is possible without your trusty portal gun. I just love the Portal 1 ending, the closing song, and, I mean, who doesn't love cake? Terrific gameplay mechanics, excellent story, and captivating atmosphere. A true FPS classic. And remember - THE CAKE IS A LIE! #FPS
