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.
The sequel to 2007's Game of the Year, Portal 2 is a hilariously mind-bending adventure that challenges you to use wits over weaponry in a funhouse of diabolical science.
Using a highly experimental portal device, you’ll once again face off against a lethally inventive, power-mad A.I. named GLaDOS. And this time you won’t be alone. Meet an expanded cast of characters as you think your way through dangerous, never-before-seen areas of Aperture Laboratories.
Break the laws of spatial physics in ways you never thought possible, with a wider variety of portal puzzles and an expansive story that spans a single player and co-operative game mode.
