Portal is a first-person puzzle game developed by Valve and set inside the mysterious Aperture Science research facility. Players control Chell, a silent test subject who is guided through a series of increasingly dangerous experiments by the artificial intelligence GLaDOS. The central mechanic is the Aperture Science Handheld Portal Device, which creates two connected portals on compatible surfaces. Players use them to redirect momentum, move objects and reach otherwise inaccessible areas while solving physics-based puzzles. Each test chamber introduces new hazards and mechanics, including weighted cubes, energy pellets and automated turrets. As the experiments continue, the sterile facility begins to reveal a darker side, turning the puzzle-solving structure into a larger escape story built around GLaDOS and the secrets of Aperture Science.







The Orange Box is a bundle that includes five titles from Valve: Half-Life 2; Half-Life 2:Episode 1; Half-Life 2: Episode Two; Team Fortress 2, the sequel to the game that put class-based, multiplayer team warfare on the map; and Portal, the game that blends puzzles, first person action, and adventure gaming to produce an experience like no other.

Break the laws of spatial physics in the hilariously mind-bending adventures of Portal and Portal 2! Including Portal and Portal 2, the Companion Collection comes with all the groundbreaking gameplay, dark humor, and exploration that earned the series hundreds of awards.
