Valve has done a lot for Mac gamers in the last few months: first releasing the popular Steam digital delivery service for OS X, then following by quickly releasing native ports of most of their catalog for Mac gamers to play. In fact, Valve managed to squirt all of their Source-engine games (including Half-Life 2, its’ episodic add-on packs, Team Fortress 2 and Portal)out the door, before their release schedule stalled due to performance issues inherent to OS X, leaving their two most resource-hungry games — the team-based zombie shooters Left 4 Dead and Left 4 Dead II in limbo.
Come Halloween, you’ll be blowing away zombies with the rest of your buddies, though. Now that Apple has ironed out the kinks in OS X through a graphics update, it seems like Valve is now getting ready to finally release the Left 4 Dead series to Mac gamers. You can now expect to be able to download Left 4 Dead and its sequel through Steam for Mac by October, along with the upcoming DLC mission pack, The Sacrifice, which bridges the stories of both titles and is fully playable under either game.
