Today, Valve announced new DLC for owners of either Left 4 Dead or Left 4 Dead 2. As a follow-up to The Passing DLC that was released last March, a new downloadable chapter called The Sacrifice will be released this October for PC, Mac and Xbox 360. It'll be playable with either the L4D or L4D2.
Remember when the original cast from L4D suddenly appeared in The Passing? I bet you were wondering when you'd get to find out what the story was with that. With The Sacrifice, the mystery will be solved as you get the chance to play the story of The Passing from the perspecitve of the cast of L4D. This time, however, Valve has added a choose your own adventure element as you get to decide which member of the original cast dies at the end of The Sacrifice. I bet that has something to do with why they named it The Sacrifice. Noodle that around a bit and get back to me.
The Sacrifice will also feature a retooled No Mercy level (the hospital level from the original game), playable with cast members from both L4D and L4D2. The Sacrifice will be out in October as a free download for PC and Mac players, but you'll have to pay if you want to play it on your Xbox 360. Start saving your points and your outrage now.
