About This Game
Portal drops you into the sterile chambers of Aperture Science as test subject Chell, armed with a portal gun that opens linked gateways on any flat surface. What begins as a deceptively simple series of physics puzzles grows into one of gaming's most celebrated stories, complete with the unforgettable AI voice of GLaDOS. By bending space to solve momentum-based challenges, you'll experience a masterclass in game design that spawned an entire genre. Widely hailed as one of the most innovative games ever made, Portal is a short but unforgettable brain-bending journey.

Full Game Overview
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.
