Portal is an action/puzzle video game from Valve, creators of Half-Life 2 and Counter-Strike. The winner of over 40 awards, including 15 Game of the Year honors, it is one of the most original games on any platform in years and offers gamers hours of unique gameplay. Set in the mysterious Aperture Science Laboratories, Portal is designed to change the way players approach, manipulate and surmise the possibilities in a given environment; similar to how Half-Life 2’s Gravity Gun innovated new ways to leverage an object in any given situation. Players must solve physical puzzles and challenges by opening portals to maneuver objects, and themselves, through space.
