Author: Valve Corporation

Undoubtedly one of the best games of all time, Valve's original Portal instantly captured the attention of gamers across the world with its innovative mechanics. However, it shone not just in its mechanics, but in its incredible storytelling, and that's where the second title stands even higher.In Portal 2, you play Chell once more, a silent test subject put through various trials by an AI under the control of Aperture Science. This time, however, you're joined by the enigmatic Wheatley, a floating, sarcastic robot. With incredible voice acting from the likes of Stephen Merchant and Ellen McLain, the story of this game unfolds in an organic, interrupted manner as you make your bid for freedom.That journey is characterized by sharp humor, a compelling backstory, and some of the most entertaining puzzle mechanics around. Inside Aperture Laboratories, Valve offers a world so devoid of emotion that the tiniest bit of humanity will stick with you. Portal was short and concise, Portal 2 is much more sprawling, and in that length, more depth is hidden.
