The first title to support Steam on a console, Portal 2 offers cross-platform matchmaking, gameplay, friends, chat, and achievements, all powered by Steam. Steam on the PS3 also saves co-op game progress and single player saved games to the Steam Cloud, enabling players to pick up where they left off on any PlayStation 3.
- The Steam overlay for PS3 provides access to both PSN and Steam friends, displaying their in-game or online status and providing a quick pathway to text chats, player profiles, friend requests, and game invites. Steam Achievements are earned in lockstep with PSN Trophies and are also accessible within the Steam overlay.
- Steam on the PS3 provides access to all of these features once the player has linked their PlayStation Network account with a Steam account, which is done right within the game. A Steam user can login to an existing account, and anyone new to Steam can create an account with the click of a button.
- In the spirit of Steam Play, linked players of the PS3 version of Portal 2 can also access and play their copy of Portal 2 on any PC or Mac by redeeming an in-box access code on their computer. The Steam client verifies the linked customer and then lists Portal 2 among their library of Steam games for PC and Mac.
