Portal is a new single-player game from Valve, creators of Half-Life 2 and
Counter-Strike. Set in the mysterious Aperture Science Laboratories, Portal has
earned over 40 awards, including 15 Game of the Year honours, and offers gamers
hours of unique gameplay.
The game 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
manoeuvre objects, and themselves, through space.
Award-winning, innovative gameplay
