We're not sure about the Xbox 360 version yet, and it doesn't appear that the PC version will come with any extra functionality to it, but the Playstation 3 version of one of the most cult-classic-great games we've ever played will be coming with both Mac and PC versions attached. This PS3 version of the game comes with full Steam integration which will allow you to continue the game wherever you left of no matter which platform you decide to bring your Portal 2 Blu-Ray disk to.
Sony and Valve (creators of Portal and now Portal 2) have collaborated on this version to bring the gamer what they consider to be one fabulous game. Gabe Newell, cofounder and president of Valve notes: "We made a promise to gamers at E3 that Portal 2 for the PlayStation 3 would be the best console version of the product. Working together with Sony we have identified a set of features we believe are very compelling to gamers. We hope to expand upon the foundation being laid in Portal 2 with more Steam features and functionality in DLC and future content releases."
In addition to instant game saves vis Steam for cross-platform play, players Steam friends will be visible and accessible for game invites and chat. This is all in one package, and the game already looks utterly fantastic, if I do say so myself. Take a peek at a trailer or two below. Portal 2 will be coming out on PC, Xbox 360, and PS3 in April 2011.
Also I'd be remiss in posting about Portal if I did so without making sure everyone heard the closing credits song as sung by the writer, Jonathan Coulton. Behold a masterpiece. I hope he's involved in number 2.
