Did You Know?


In the lead up to the game's release, numerous edits were made to the original Portal, to both accommodate Portal 2, and to embed teasers for it, right inside the original. These edits were automatically patched into all copies of the game by the Steam software. The most notable change to Portal was that the ending was retconned so that now Chell *doesn't* escape the facility, but is instead dragged back inside by a robot, right after defeating GLaDOS (Hence explaining her need to escape all over again in this game). Another significant change was that radios were added to all the original test chambers. Each one of these radios, if placed in a certain location, will emit SSTV sounds, a primitive form of television broadcasting, which if decoded, provide users with various teaser images associated with Portal 2. Incidentally, a similar SSTV easter egg is hidden somewhere within Portal 2. See more »


Cave Johnson: Science isn't about *why* - it's about *why not*. *Why* is so much of our science dangerous? Why not *marry* safe science if you love it so much? In fact, why not invent a special safety door that won't hit you in the butt on the way out, because *you are fired!* Not you, test subject. You're doing fine.
[to someone else]
Cave Johnson: Yes, *you*. Box. Your stuff. Out the front door. Parking lot. Car. Goodbye.

User Reviews

for science...
27 April 2011 | by (Livigno) – See all my reviews

"You are now thinking in portals..." - this used to be the tag line for an underdog game-project which completed the Orange Box. While most of the people bought this product because of Half Life 2 - Episode 2 the main feature only had limited playtime. After exploring the game set of the the Orange Box players were stunned by "Portal", an ego-shooter with no shooting and parallels to the Half Life universe.

In fact it was only a matter of time until the huge testing facility of Aperture Science got revived for the next run - and story.

While Portal 1 was pretty much done within 3 hours its successor waits with 7-8 hours of fun. It appears a little short - that's where the co-op mode comes in, adding almost a new dimension to the game's paradigm. Solving puzzles, mazes and riddles with a partner not only opens up possibilities of creating problems to solve - it also enhances one's horizon of thinking. The co-op mode does not really develop a story, but just for the fact that after solving some puzzles ("tests") the player is left with an unique impression, this games deserves a huge credit.

The story picks up where its predecessor left off - but digs way deeper into the history and structures around Aperture Science. It's a delight to move through very different environments solving unique puzzles which are created with a particular love for details. After some rooms the player occasionally feels like a genius because the presentation of problems are extremely unusual. The voices you are accompanied by dramatically raise the level atmosphere as the voice actors do (typical for Valve) an exceptional job. The whole flow of the game grants a fluid game-play and hardly ever comes to halt.

To me personally the main point of praise is the fact that Valve manages to send you through approximately 8 hours of the same game-play without making it boring. The story is appealing, unique and weaves in seamlessly into the Half Life universe.

Two things that I thought were not quite state of the art: 1. The graphics engine is out of date, no doubt. For this game it isn't THAT important to have the latest graphics, still it's very apparent at some point and very untypical for Valve. 2. Many aspects are almost too familiar from part one. The showdown, the credits, some monologues and game-plays, etc...

BUT, some other aspects would receive more than just 10 points and that's why Portal 2 still deserves a solid score of 9 points.

Let's face it: Valve produces games which are far more than the average assembly-line-games pumped out every year. The love for detail, interaction, presentation of problems, dialogs, story and game-play clearly stands out in comparison to even major game developer studios. And Portal 2 continues this tradition seamlessly - yes, I may have expected "a little" more but in the end it's still another magnum opus which will be talked about for a long time. No doubt, this game is already one of 2011's highlights and even though other games have way better effects, graphics, models or realism - Valve draws a very clear line: While other studios produce games, they craft art!
