Portal 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. 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. A Mac OS X version was released as part of the Mac-compatible Steam platform on May 12, 2010. 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.Portal 2 is a 2011 first-person puzzle-platform video game developed and published by Valve Corporation. It is the sequel to Portal (2007) and was released on April 19, 2011 for Microsoft Windows, Mac OS X, Linux (Linux is currently only in the beta channel of Steam), PlayStation 3, and Xbox 360. The retail versions of the game are distributed by Electronic Arts while online distribution of the Windows, OS X and Linux versions is handled by Valve's content delivery service, Steam. Portal 2 was announced on March 5, 2010, following a week-long alternate reality game based on new patches to the original game. Before the game's release on Steam, the company released the Potato Sack, a second multi-week alternate reality game, involving 13 independently developed titles which culminated in a distributed computing spoof to release Portal 2 several hours early.The game retains Portal's gameplay elements, and adds new features, including tractor beams, laser redirection, bridges made of light, and paint-like 'gels' accelerating the player's speed, allowing the player-character to jump higher or place portals on any surface. These gels were created by the team from the Independent Games Festival-winning DigiPen student project Tag: The Power of Paint. In the single-player campaign, the player controls protagonist Chell, awoken from suspended animation after many years, who must navigate the now-dilapidated Aperture Science Enrichment Center during its reconstruction by the reactivated GLaDOS, a powerful supercomputer. The storyline introduces new characters, including Wheatley (Stephen Merchant) and Cave Johnson (J. K. Simmons). Ellen McLain reprised the role of GLaDOS. Jonathan Coulton and The National each produced a song for the game. Portal 2 also includes a two-player cooperative mode, in which the robotic player-characters Atlas and P-Body are each given a portal gun and are required to work together to solve puzzles. Valve provided post-release support for the game, including additional downloadable content and a simplified map editor to allow players to create and share test chambers with others.Although some reviewers initially expressed concerns about the difficulty of expanding Portal into a full sequel, Portal 2 received universal acclaim upon its release, with the game's writing, pacing, and dark humor being highlighted as stand-out elements. The voice work of McLain, Merchant, and Simmons were heavily applauded by critics, and the new gameplay elements, the game's challenging but surmountable learning curve, and the additional cooperative mode also received praise. Some gaming journalists ranked Portal 2 among the top games of 2011, and several named it their Game of the Year.
Insert QuoteI finished the first one, and played the multyplayer of the second, didn't play the campaign Oo.
Why not? Story is really good.
I played both of them and they are great! What a shame that Valve hasn't launched another Portal or Half Life...
