Portal is a 2. 00. Valve Corporation. The game was released in a bundle package called The Orange Box for Microsoft Windows and Xbox 3. October 9, 2. 00. Play. Station 3 on December 1.
The Windows version of the game is available for download separately through Valve's content delivery system Steam and was released as a standalone retail product on April 9, 2. A standalone version called Portal: Still Alive was released on the Xbox Live Arcade service on October 2. An OS X version was released as part of the Mac- compatible Steam platform on May 1. A Linux version was released on Steam as a beta on May 2, 2. June 2. 4, 2. 01. An Android port for the Nvidia Shield was released on May 1.
The game primarily comprises a series of puzzles that must be solved by teleporting the player's character and simple objects using "the Aperture Science Handheld Portal Device", a device that can create inter- spatial portals between two flat planes. The player- character, Chell, is challenged by an artificial intelligence named GLa. DOS (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 game's unique physics allows momentum 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 Digi.
Pen 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 2. The game received praise for its unique gameplay and darkly humorous story. It received acclaim for the character of GLa. DOS, voiced by Ellen Mc. Lain in the English- language version, and the end credits song "Still Alive" written by Jonathan Coulton for the game. Not counting sales through Steam, over four million copies of the game have been sold since its release.
The game's popularity has led to official merchandise from Valve including plush Companion Cubes, as well as fan recreations of the cake and portal gun. A sequel, Portal 2, was released in 2. Gameplay[edit]A representation of how the (magnitude of) linear momentum is conserved through portals. By jumping into the blue portal, the character is launched out of the orange portal and onto the platform on the right.
A more advanced portal technique. The character builds up speed using two blue portals, to reach an otherwise unreachable area. The second blue portal is carefully created in mid- air, after exiting the orange portal for the first time, destroying the first blue portal in the process. In Portal, the player controls the protagonist, Chell, from a first- person perspective as she is challenged to navigate through a series of rooms using the Aperture Science Handheld Portal Device, or portal gun, under the watchful supervision of the artificial intelligence GLa. DOS. The portal gun can create two distinct portal ends, orange and blue. The portals create a visual and physical connection between two different locations in three- dimensional space. Neither end is specifically an entrance or exit; all objects that travel through one portal will exit through the other.
An important aspect of the game's physics is momentum redirection. As moving objects pass through portals, they come through the exit portal at the same direction that the exit portal is facing and with the same speed with which they passed through the entrance portal.[1. For example, a common maneuver is to jump down to a portal on the floor and emerge through a wall, flying over a gap or another obstacle. This allows the player to launch objects or Chell over great distances, both vertically and horizontally, referred to as 'flinging' by Valve. As GLa. DOS puts it, "In layman's terms: speedy thing goes in, speedy thing comes out." If portal ends are not on parallel planes, the character passing through is reoriented to be upright with respect to gravity after leaving a portal end. Chell and all other objects in the game that can fit into the portal ends will pass through the portal. However, a portal shot cannot pass through an open portal; it will simply deactivate or create a new portal in an offset position.
Creating a portal end instantly deactivates an existing portal end of the same color. Moving objects, glass, special wall surfaces, liquids, or areas that are too small will not be able to anchor portals. Chell is sometimes provided with cubes that she can pick up and use to climb on or to hold down large buttons that open doors or activate mechanisms. Particle fields known as emancipation grills, occasionally called "fizzlers" in the developer commentary, exist at the end of all and within some test chambers; when passed through, they will deactivate any active portals and disintegrate any object carried through. The fields also block attempts to fire portals through them.[1. Although Chell is equipped with mechanized heel springs to prevent damage from falling, she can be killed by various other hazards in the test chambers, such as turret guns, bouncing balls of energy, and toxic liquid.
She can also be killed by objects falling through portals, and by a series of crushers that appear in certain levels. Unlike most action games at the time, there is no health indicator; Chell dies if she is dealt a certain amount of damage in a short time period, but returns to full health fairly quickly. Some obstacles, such as the energy balls and crushing pistons, deal fatal damage with a single blow. Game. Spot noted, in its initial review of Portal, that many solutions exist for completing each puzzle, and that the gameplay "gets even crazier, and the diagrams shown in the trailer showed some incredibly crazy things that you can attempt."[1. Two additional modes are unlocked upon the completion of the game that challenge the player to work out alternative methods of solving each test chamber. Challenge maps are unlocked near the halfway point and Advanced Chambers are unlocked when the game is completed.[1.
In Challenge mode, levels are revisited with the added goal of completing the test chamber either with as little time, with the least number of portals, or with the fewest footsteps possible. In Advanced mode, certain levels are made more complex with the addition of more obstacles and hazards.[1.
Synopsis[edit]Characters[edit]The game features two characters: the player- controlledsilent protagonist named Chell, and GLa. DOS (Genetic Lifeform and Disk Operating System), a computer artificial intelligence that monitors and directs the player.
In the English- language version, GLa. DOS is voiced by Ellen Mc. Lain, though her voice has been altered to sound more artificial. The only background information presented about Chell is given by GLa. DOS; the credibility of these facts, such as Chell being adopted, an orphan, and having no friends, is questionable at best, as GLa.
DOS is a liar by her own admission. In the "Lab Rat" comic created by Valve to bridge the gap between Portal and Portal 2, Chell's records reveal she was ultimately rejected as a test subject for having "too much tenacity"—the main reason Doug Rattman, a former employee of Aperture Science, moved Chell to the top of the test queue.[2. Setting[edit]. The logo for Aperture Science Laboratories. Portal takes place in the Aperture Science Laboratories computer aided enrichment center—Aperture Science in short—which is a research corporation responsible for the creation of the portal gun.
According to information presented in Portal 2, the location of the complex is in the Upper Peninsula of Michigan. Information about the company, developed by Valve for creating the setting of the game, is revealed during the game and via the real- world promotional website.[2. According to the Aperture Science Web site, Cave Johnson founded the company in 1. U. S. military. However, after becoming mentally unstable from "moon rock poisoning" in 1.
Johnson created a three- tier research and development plan to make his organization successful. The first two tiers, the Counter- Heimlich Maneuver (a maneuver designed to ensure choking) and the Take- A- Wish Foundation (a program to give the wishes of terminally ill children's parents to adults who are in need of dreams), were commercial failures and led to an investigation of the company by the U. S. Senate. However, when the investigative committee heard of the success of the third tier, a man- sized ad- hoc quantum tunnel through physical space with possible applications as a shower curtain, it recessed permanently and gave Aperture Science an open- ended contract to continue its research. The development of GLa.
DOS, an artificially intelligent research assistant and disk- operating system, began in 1. Black Mesa's work on similar portal technology.[2. A presentation seen during gameplay reveals that GLa. DOS was also included in a proposed bid for de- icing fuel lines, incorporated as a fully functional disk- operation system that is arguably alive, unlike Black Mesa's proposal, which inhibits ice, nothing more.[2.
