Left 4 Dead 2 DLC will include Left 4 Dead 1, too
Nobody’s heard much from the Left 4 Dead 2 developers recently, but now they’ve explained that’s because they’ve been working on a surprise!
They’re planning a new DLC release, and it will include (among other things) the three remaining Left 4 Dead 1 campaigns – so if you’ve got the second game you’ll soon have all of the first game as a bonus. (No Mercy was already featured in The Sacrifice DLC pack, remember?)
