After starting Portal 2 on PlayStation®3, bring up the Steam Overlay by pressing the SELECT on your PS3™ controller. If you are not yet logged in to the PlayStation®Network, you will be prompted to do so here.
You will then be prompted to either log in to an existing Steam account, or create a new one.

Each new copy of Portal 2 on PlayStation® 3 includes a one-time use code allowing you access to the game on Windows or Mac through Steam.

Only PlayStation® 3 split-screen co-op can be played using a single copy of the game. When you purchase a new copy of Portal 2 for PlayStation® 3, you will receive an in-box code which provides your linked Steam account with access to your copy of Portal 2 on your computer.

Steam Cloud is automatically enabled once you've linked your PSN and Steam accounts.
Portal 2 for PlayStation® 3 supports Steam Cloud, which allows settings, saves, and progress to be transferable from one PlayStation® 3 to another, or from any computer to another computer.
Game saves and progress from a PlayStation® 3 are incompatible with other platforms (i.e. Windows or Mac). Steam Cloud data from a PlayStation® 3 can only be used with another PlayStation® 3 logged in to the same PSN ID.
Save files stored on Steam Cloud for your PSN ID will not interfere with Steam Cloud save files stored for your Windows or OSX computer.
To access Steam Cloud settings for the PlayStation® 3, you must first log in to your linked PSN account.
Once you have done so, you may access the Steam Cloud menu from either the Load Game or Save Game screens
While on either the Save or Load screen, press the TRIANGLE button to access the Steam Cloud settings, where you can select the number of saves to sync. Steam Cloud will sync the most recently made saves , allowing you to pick up where you left off on any PlayStation® 3.
Choosing to sync more saves may result in longer download and sync times for your save data when starting the game on another PlayStation® 3.
