As expected, the PS3 version of Portal 2 will feature full cross-platform compatibility with the PC and Mac versions of the game. According to a recent press release, PS3 owners will be able to chat and jump into matchmaking with PC and Mac users, and they’ll also be able to save their game using Steam’s cloud-based service, ensuring that progress is never lost when switching platforms.
And speaking of different platforms, the PC and Mac version of Portal 2 will also come free to PS3 users who link their PSN and Steam accounts, much like how the Mac version of a Steam Play game comes free to PC owners.
"We made a promise to gamers at E3 that Portal 2 for the PlayStation 3 would be the best console version of the product," Valve head honcho Gabe Newell said in a statement. "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," he said.
The PS3 version of Portal 2 was announced back at Sony’s E3 2010 press briefing and traditional Steamworks functionality was promised at the event. This version of the game is still slated to ship day and date with the PC, Mac, and Xbox 360 versions in April, 2011.
