Valve Confirms Mac Versions Of Steam, Valve Games

"We are treating the Mac as a tier-1 platform, so all of our future games will release simultaneously on Windows, Mac, and the Xbox 360," said Cook. "Updates for the Mac will be available simultaneously with the Windows updates."

Mac and PC users will effectively share a single platform for Valve games. Valve's Steamworks suite of online authentication and game features, which an increasing number of third-parties are using in their own games, will be fully-supported on Mac, and Valve says its server and client code is fully interoperable -- owners of either platform can play in the same multiplayer servers.

With games that support "Steam Play," including Valve's own games, players can install both PC and Mac versions and load up either one on their respective computers. Those games also support cross-platform Steam Cloud use, retaining settings and save games regardless of system.

See Modern Warfare's "No Russian" Like You've Never Seen It Before

Michael Barnes is the man to thank for this incredible piece of Modern Warfare 2 machinima, which recreates the game's controversial "No Russian" mission in a manner fit for prime-time TV.

What you're seeing here is almost entirely in-game action from the PC version of the game. What Barnes has done is record it from different camera angles than the game's standard first-person perspective, then cut it together to look like a movie or TV show.

The results are a lot more exciting than the actual mission turned out to be.
