Left 4 Dead 2 is a cooperative first-person shooter game. It is the sequel to Valve Corporation’s award-winning Left 4 Dead. The game launched on November 17, 2009, for Microsoft Windows and Xbox 360 in the United States; it launched November 20 in Europe.It builds upon the cooperatively-focused gameplay of the original and uses Valve’s proprietary Source engine, the same game engine used in Left 4 Dead.
“The Sacrifice,” confirms that the game’s sequel is coming to the Mac today, October 5th. Left 4 Dead 2 will be released, as have all of the Source games, under the Steam Play banner. That means if you own it on the PC, you also own it on the Mac, so all you’ll have to do is download and start shooting zombies.
Left 4 Dead 2 for Mac OS X users will come bundled with the original title plus the 3 DLC add-ons including “No Mercy”, “The Sacrifice”, and “The Passing”. The same as all Mac and PC compatible titles on Steam, users that have already purchased the PC version of Left 4 Dead 2 will be able to download the title for Mac for free.
Anyone who buys the game on Steam will get all of the DLC for free, which makes for the original five campaigns plus the three DLC levels to play through. That’s an excellent deal for sure.
Unfortunately, the first game is not yet ready for the Mac; apparently, it’s taking Valve a little longer than expected to get it OS X-compatible. But Valve promises that when it is released, Steam owners will get the same deal — all the DLC with the game itself.
