The original Portal shipped with each copy of the Orange Box and was used pre-dominantly as a trial puzzle experience, which managed to surpass even Valve’s high expectations. Portal 2 develops on the original combining bigger levels, more dynamic puzzles, online co-op and for PS3 members, the ability to play with PC users, and transfer your game across platforms. 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 PlayStation3.
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 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.
Portal 2 has already hit a metacritic rating of 95, taking the crown of the highest rated game of 2011, but with Batman Arkham City, Gears of War 3 and at least one more COD title to come before the years out will it be able to hold on………
