Compare Portal prices across trusted key stores and find the best deal. Developed by Valve. Published by Valve. Released on 10/10/2007. Available on PC, Linux. Genres: Action. Metacritic score: 90/100.

A three-hour puzzle game that rewired how an entire generation thinks about first-person movement, and it's still doing it to new players right now.

I've replayed Portal more times than I can honestly justify, and every single run the portal gun still feels like a trick my brain shouldn't be able to pull off. That's the core achievement here: Valve built a first-person puzzle game around a single tool, the Aperture Science Handheld Portal Device, and engineered nineteen test chambers that teach you to weaponize momentum, redirect laser-like energy balls, stack weighted cubes, dodge sentry turrets, and fold space in ways that feel genuinely clever rather than arbitrary. The puzzle escalation is pitch-perfect. You start moving a box from point A to point B through a single portal. A few chambers later you're calculating fall velocity to fling yourself across a room using two portals and conservation of momentum as the actual mechanic. The game never explains this in a physics lecture; it just builds the logic until you feel it in your hands. The one thing that elevated Portal from a smart tech demo into a genuine classic is GLaDOS, voiced by Ellen McLain. Early playtests showed that without some kind of antagonist and narrative threat, players finished the chambers and asked when the real game would start. GLaDOS was the answer to that problem, and she solved it so well that she became one of the most recognized characters in game history. Her passive-aggressive guidance starts warm and clinical, then grows increasingly hostile as you push deeper into the Enrichment Center. The dark humor is dry and consistent, never overselling the joke, and it makes the sterile white corridors feel genuinely unsettling rather than boring. The Weighted Companion Cube, the wall graffiti hinting at secrets, the glimpses of the world behind the test chamber panels: Portal hides a real atmosphere underneath the clean surfaces, and finding it is half the fun. The honest criticism is the one everyone already knows: the game is short. Skilled players can finish it in under two hours; a first-timer who stops to think will get three to four hours out of it. There is no co-op mode, no procedurally generated content, and the challenge modes accessible after the credits are better suited to speedrunners and completionists than casual players hungry for more story. The Source engine visuals are dated by modern standards, and some players report mild motion discomfort from the first-person perspective during the more acrobatic portal sequences. None of that changes the fundamental reality that within its short runtime Portal does one thing so well that it influenced years of puzzle design after it. If you have never played it, this is the rare case where the critical consensus is not hype. The Metacritic score of 90 understates the cultural footprint. If you played it years ago, a replay still holds up: the puzzle logic is timeless even if the textures are not. The only players who should approach with caution are those who genuinely have no patience for physics-based thinking and prefer action over problem-solving, because Portal will not meet you halfway on that. For everyone else, start here before Portal 2, not because you have to, but because the original's stripped-down tension and dread hit differently than the sequel's broader comedy. Alex, Scout Team
