Left 4 Dead 1 and 2 DLC “The Sacrifice” Released, Both Games on Sale

Zombie fans, rejoice. Valve has released the newest DLC for Left 4 Dead 1 and 2, The Sacrifice. If you’re a L4D2 owner, you’ll also get the L4D ‘No Mercy’ campaign in this update.

This release also marks the arrival of Left 4 Dead 2 on the Mac platform. To encourage those who haven’t gotten their hands on one or both of the zombie shooters yet, Valve’s got both of them on sale on Steam this week.

You can pick up either game for only $6.79, or you buy both of them together for a measly $10.19. This deal likely won’t last long, so if you want either of these games, get on over to Steam.

If you want to see how the story of The Sacrifice ends, Valve’s also rolled out the fourth and final installment of their companion comic. You can check out part 4 (and all three previous releases) right here.

There are a number of other changes included in this patch. To keep you up to date, we’ve included the patch notes below. Happy zombie slaying!
