Valve is to bring a number of Steam features to the PlayStation 3, the first time the leading PC digital service has featured on a home console.
The PlayStation 3 version of first-person puzzler Portal 2 will feature cross-platform multiplayer gaming, voice chat and cloud storage of game saves.
"We made a promise to gamers at E3 that Portal 2 for the PlayStation 3 would be the best console version of the product," commented Gabe Newell, co-founder and president of Valve.
"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, PlayStation 3 owners will be able to unlock a Steam Play version of the game for PC or Mac for free by linking PlayStation Network and Steam accounts, when the game is released this April.
"We designed the Portal 2 PS3 experience to be very straightforward for gamers," added Josh Weier, project lead on Portal 2 at Valve.
"PS3 gamers will be able to simply drop the Blu-ray 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."
