You wake to find yourself in a small, square, glass room containing a futuristic-looking tube-like bed, a toilet, and a table with a radio playing a tune on it alongside a mug and a clipboard with data on it. A timer is counting down from a minute just above the closed door leading out of the small room. A voice sounds from a speaker in the ceiling of the room. After some things are said, the voice becomes distorted for a second, sparks come out of the speaker, and the voice returns to normal. It counts down from five, synchronized with the timer above the door. At zero, the door opens, and you are released from your cell.... Written by mboharsik

GLADoS' voice has the same tonality as the voice of the computer system in the science fiction cult film The Thirteenth Floor (1999), a film about alternate realities. See more »


When Valve attempted to solve the error of Chell being able to fall from incredible heights, it added the plug leading from the back of her foot to the back of her knee to strengthen her muscles. However, without any back support including an exoskeleton or bars stronger than human bones, there is no way she can be completely protected. See more »


GLaDOS: As part of an optional test protocol, we are pleased to present an amusing fact: The device is now more valuable than the organs and combined incomes of everyone in *subject hometown here.*

Brilliant game!!!
8 April 2008 | by (United States) – See all my reviews

Portal is a work of genius, hands down. Only genius can use cake as a philosophic standpoint, argue to kill an inanimate object, and give you sufficient reason to love things out to kill you (much less call them cute). Further more, what kind of game is this? is it a first-person-shooter? a puzzle game? a comedy? It is (more or less) all three...

Without giving too much away, you play as a character (later on named Chell) that receives a device capable of producing portals. These portals allow you to travel across a room, walking in one portal and out the other instantly. You are guided through an expanse of testing and experimentation by a computer known simply as "GLaDOS", or Generic Lifeform and Disk Operating System. Things are not quite as they seem while you make your way through the Aperture Science Enrichment Center.

This game is worth the attention, and probably the most inventive thing I've seen out of the gaming world in my life. Get it. Now. =)
