Portal™ is a single-player game from Valve set in the mysterious Aperture Science labs that has been hailed as one of the most innovative games on the market and offers hours of unique gameplay.
Portal was designed to change the way players approach the game environment, manipulate its elements, and estimate its possibilities, much like the gravity weapon in Half-Life® 2 innovated ways to use objects appropriately for the situation at hand.
Players must solve physics puzzles by opening portals and then maneuvering objects, their character, or both at the same time.
