In October of 2007 Portal was released as part of a package called The Orange Box. While playing Portal and as you’ll see often in the Portal Walkthroughs, the Aperture Science Handheld Portal Device (also known as teh ASHPD or Portal Gun) is a critical aspect of the game. The name Portal comes from the fact that the main character is teleported throughout the games puzzles and various levels. On this site you can see various examples of Portal walkthrough videos were the main characters, Chell and GlaDOS, are achieving even the most difficult tasks. Feel free to make use of the Portal Walkthrough rating system and rate each portal walkthrough video you watch.

Although Portal is a bit short compared to other similar games, it is highly regarded as one of the most original and addicting games to come along in a while.
