Valve released some tasty information on GameTrailers TV last night. Firstly being a teaser trailer for Portal 2‘s co-op (which you can view after the break) but, more interestingly, we got details of a new campaign coming to Left 4 Dead 1 and 2. Releasing October 5th, the new three-level campaign will be titled The Sacrifice and will focus on the events of the original survivors’ struggle just before the meet up with Left 4 Dead 2‘s survivors in the previous DLC campaign, The Passing. And of course, the DLC will come to PC gamers at no charge.
The content doesn’t end there! L4D2 will also be getting L4D1‘s No Mercy campaign and Valve will start releasing a massive 150-page online comic this September. The comic will tie up the two Left 4 Dead storylines and the events leading up to The Sacrifice.
