Overview

Portal is a first person game. It consists primarily of a series of puzzles that must be solved by teleporting the player's character and simple objects using the "Aperture Science Handheld Portal Device", also referred to as the "portal gun", a device that can create portals between locations in the puzzles. The player character, Chell, is challenged and taunted by an artificial intelligence construct named GLaDOS (Genetic Lifeform and Disk Operating System) to complete each puzzle in the Aperture Science Enrichment Center using the portal gun with the promise of receiving cake when all the puzzles are completed. The Source engine's physics system allows kinetic energy to be retained through portals, requiring creative use of portals to maneuver through the test chambers. This gameplay element is based on a similar concept from the game Narbacular Drop; many of the team members from the DigiPen Institute of Technology who worked on Narbacular Drop were hired by Valve for the creation of Portal.

Portal was acclaimed as one of the most original games of 2007, despite some criticism for its short duration. It received praise for its originality, unique gameplay, dark story and sense of comedy. The character of GLaDOS, voiced by Ellen McLain, received acclaim for her unique characterization and the end credits song "Still Alive", written by Jonathan Coulton, was praised for its original composition and humor. Portal is often cited as one of the greatest video games ever made. Excluding Steam download sales, over four million copies have been sold, spawning merchandise from Valve including a model portal gun and plush Companion Cubes, as well as fan recreations of the cake.
