Originally released as part of The Orange Box, Portal was heralded as a ground-breaking puzzle platforming game that changed the way players could approach, manipulate, and surmise the possibilities in a given environment. Throughout Portal, which is played from a first-person perspective, players must solve physical puzzles and challenges by opening portals to maneuver objects, and themselves, through space. The game also leverages a darkly humorous narrative as players adventure and puzzle their way through the mysterious Aperture Science Laboratories.

Portal 2 is the hilariously mind-bending adventure that again challenges players to use wits over weaponry in a funhouse of diabolical science. Using the highly experimental Portal device, players once again face off against a lethally inventive, power-mad A.I. named GLaDOS. Players meet an expanded cast of characters as they think their way through dangerous, never-before-seen areas of the laboratories and a wider variety of portal puzzles.

Plus Portal 2 also includes a co-operative game mode with local, split-screen and online multiplayer.

Portal: Companion Collection is coming to Nintendo Switch (eShop) in 2022 for a targeted price of $19.99.
