Note:
Each code is unique and non-transferrable, and can only be registered to a single Steam account.
To redeem this code, please take the following steps:
After you have linked your Steam account and your PSN ID, log in to Steam on Windows or Mac. If you do not yet have Steam, download the software here.
On your PC, launch the Steam application and log in to your account. If you created a new Steam account using the Steam Overlay on PlayStation®3, on the log-in screen, select “PS3™ - First time signing in?”, which will guide you through the first-time Steam login via your PlayStation®Network account (you will then be asked to set up your account credentials)
Once you have logged in to the account, go to the “Games” menu along the top, choose “Activate a Product on Steam”, and enter the key provided on the card included in the game’s packaging.
After this key has been activated, the game can be downloaded and played by selecting “Library”, and then double-clicking on “Portal 2”.
Note:
The PlayStation®3 game disc for Portal 2 cannot be used to install the game in Windows or OSX. Instead, your computer will download the correct version of the game through Steam.
