Portal

Portal is a critically acclaimed puzzle-platformer video game developed by Valve Corporation. Released in 2007, the game introduces a unique gameplay mechanic centered around the use of a handheld device called the “Portal Gun,” allowing players to create linked portals on flat surfaces. Players, as Chell, navigate a series of increasingly complex puzzles within the Aperture Science research facility, guided by the artificial intelligence GLaDOS. The game is praised for its innovative mechanics, engaging narrative, dark humor, and the iconic song “Still Alive.”
