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. 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 GLaDOS 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.

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.GameSpot 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."

A sequel, ''Portal 2'', was released in 2011, adding several new gameplay mechanics and a cooperative multiplayer mode.==Gameplay==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 GLaDOS. 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. 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 GLaDOS 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.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.GameSpot 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." 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.

A standalone version called '''''Portal: Still Alive''''' was released on the Xbox Live Arcade service on October 22, 2008; this version includes an additional 14 puzzles. An OS X version was released as part of the Mac-compatible Steam platform on May 12, 2010. A Linux version was released on Steam as a beta on May 2, 2013,(【引用サイトリンク】 title= Portal Beta released ) and came out of beta on June 24, 2013.(【引用サイトリンク】 Portal Update Released ) An Android port for the Nvidia Shield was released on May 12, 2014.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 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 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 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 being considered short in length. The game received praise for its unique gameplay and darkly humorous story. It received acclaim for the character of GLaDOS, voiced by Ellen McLain 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 2011, adding several new gameplay mechanics and a cooperative multiplayer mode.==Gameplay==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 GLaDOS. 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. 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 GLaDOS 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.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.GameSpot 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." 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. 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.」の詳細全文を読む

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.

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.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.GameSpot 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." 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.

' is a 2007 first-person puzzle-platform video game developed by Valve Corporation. The game was released in a bundle package called ''The Orange Box'' for Microsoft Windows and Xbox 360 on October 9, 2007, and for the PlayStation 3 on December 11, 2007.(【引用サイトリンク】The Orange Box (PC) )(【引用サイトリンク】title=The Orange Box (Xbox 360) )(【引用サイトリンク】title=The Orange Box (PS3) ) 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, 2008. A standalone version called ''Portal: Still Alive''''' was released on the Xbox Live Arcade service on October 22, 2008; this version includes an additional 14 puzzles. An OS X version was released as part of the Mac-compatible Steam platform on May 12, 2010. A Linux version was released on Steam as a beta on May 2, 2013,(【引用サイトリンク】 title= Portal Beta released ) and came out of beta on June 24, 2013.(【引用サイトリンク】 Portal Update Released ) An Android port for the Nvidia Shield was released on May 12, 2014.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 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 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 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 being considered short in length. The game received praise for its unique gameplay and darkly humorous story. It received acclaim for the character of GLaDOS, voiced by Ellen McLain 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 2011, adding several new gameplay mechanics and a cooperative multiplayer mode.==Gameplay==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 GLaDOS. 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. 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.

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 2011, adding several new gameplay mechanics and a cooperative multiplayer mode.==Gameplay==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 GLaDOS. 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. 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 GLaDOS 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.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.GameSpot 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." 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.

'Portal'' is a 2007 first-person puzzle-platform video game developed by Valve Corporation.

The player-character, Chell, is challenged by an artificial intelligence 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.

A standalone version called '''''Portal: Still Alive''''' was released on the Xbox Live Arcade service on October 22, 2008; this version includes an additional 14 puzzles. An OS X version was released as part of the Mac-compatible Steam platform on May 12, 2010. A Linux version was released on Steam as a beta on May 2, 2013,(【引用サイトリンク】 title= Portal Beta released ) and came out of beta on June 24, 2013.(【引用サイトリンク】 Portal Update Released ) An Android port for the Nvidia Shield was released on May 12, 2014.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 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 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 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 being considered short in length. The game received praise for its unique gameplay and darkly humorous story. It received acclaim for the character of GLaDOS, voiced by Ellen McLain 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 2011, adding several new gameplay mechanics and a cooperative multiplayer mode.==Gameplay==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 GLaDOS. 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. 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 GLaDOS 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.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.GameSpot 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." 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. 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.」の詳細全文を読む

' was released on the Xbox Live Arcade service on October 22, 2008; this version includes an additional 14 puzzles. An OS X version was released as part of the Mac-compatible Steam platform on May 12, 2010. A Linux version was released on Steam as a beta on May 2, 2013,(【引用サイトリンク】 title= Portal Beta released ) and came out of beta on June 24, 2013.(【引用サイトリンク】 Portal Update Released ) An Android port for the Nvidia Shield was released on May 12, 2014.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 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 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 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 being considered short in length. The game received praise for its unique gameplay and darkly humorous story. It received acclaim for the character of GLaDOS, voiced by Ellen McLain 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 2011, adding several new gameplay mechanics and a cooperative multiplayer mode.==Gameplay==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 GLaDOS. 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. 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 GLaDOS 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.
