About Portal
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 maneuvering objects, and themselves, through space.
