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

Timers that are counting down in the game aren't counting down to zero correctly. When the timer reaches 00:01:00 it immediately resets to zero, instead of counting the last second as well. GLaDOS is also saying the numbers at the wrong moment, for example, she says two when the timer says 00:02:59, when she should have said it when the timer read 00:02:00. (However, these errors were corrected when the game was released for Mac OS X.) See more »


GlaDOS: Momentum, a function of mass and velocity, is conserved between portals. In layman's terms, speedy thing goes in, speedy thing comes out.

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. =)
