Portal 2 PS3 Has Cross-Platform PC-PS3 Multiplayer, Free PC Version

Valve Software revealed more details about the previously-announced Steam support for the PlayStation 3 version of the upcoming puzzle-heavy shooter Portal 2.

Newly-announced Steam features in the PS3 version of the game include support for PC/Mac-to-PS3 multiplayer play, cloud-based storage of PS3 save games and cross-platform chat (there is no announced support for PS3-to-PC/Mac cloud-based game saves).

When the game launches on PS3 in April this year, it will be the first time that PC-derived Steam functionality will appear on any home console. The game is coming to PS3, PC, Mac and Xbox 360, the latter of which will not have Steam functionality.

PlayStation 3 gamers who buy Portal 2 will also be able to unlock a Steam Play copy of the game (i.e. the full PC/Mac version) for free by linking their PlayStation Network accounts with Steam.
