About the game
An inventive first-person puzzle game where you solve spatial challenges using a gun that creates linked portals on surfaces. Set in the mysterious Aperture Science labs, it guides you through test chambers under the watchful eye of the sinister AI GLaDOS.
Did you know?
Portal grew out of the student project Narbacular Drop, whose entire team Valve hired, and its ending song Still Alive by Jonathan Coulton became a cult hit.

FAQ
Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. That's why we only list sellers with buyer protection.
Which key region should I pick?
Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.
What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
What's the difference between editions?
Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
