That right. For those of you who buy Portal 2 for PS3, you will be pleased to know that you will get a free copy of Portal 2 for your PC/Mac via Steam. Back at E3 when the game was first announced, there were vague details as to what kind of Steam elements were gonna be added to the Portal 2 experience. Those details have finally surfaced. For the first time ever on the Playstation 3, gamers will be able to go head to head with PC and Mac gamers. Yes that’s right, cross-platform gaming, however this feature is not available on the Xbox 360 version. Along with the cross platform multiplayer, Steam cloud for game saves so that you can take your gaming from the Playstation 3 to your PC or Mac that has Steam installed.

In order to get your free copy of Portal 2 on your PC or Mac. You will need to link your PSN account to your Steam account. Portal 2 project lead Josh Weier explains that Valve has designed the cross-platform experience to be hassle-free: “PS3 gamers will be able to simply drop the Bluray disc in the PS3, link to their Steam account from inside the game, and all their Steam friends (on PC and Mac) will be visible and accessible for chat and game invites.”

With this kind of news I hope to see games like the Left 4 Dead series, as well as a remake of The Orange Box make its way on to the Playstation 3 along with the same features Portal 2 has.
