A Steam user can login to an existing account, and anyone new to Steam can create an account with the click of a button. 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.

Steam Achievements are earned in lockstep with PSN Trophies and are also accessible within the Steam overlay. The Steam overlay for PS3™ provides access to 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 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 first title to support Steam on a console, Portal 2 offers cross-platform matchmaking, gameplay, friends, chat, and achievements, all powered by Steam. Valve, creator of best-selling game franchises (such as Half-Life, Portal, Left 4 Dead, and Counter-Strike) and leading technologies (such as Steam and Source), today disclosed details regarding the Steam experience designed for the PlayStation®3, which is set to debut next week with the release of Portal 2.
