Valve has announced
that the next batch of Left 4 Dead 2
DLC will include a user-created campaign known as "Cold Stream." Created by Matthew Lourdelet -- known for his "2 Evil Eyes" campaign -- the as yet unfinished Cold Stream campaign will begin community testing within the "next few weeks."
The DLC is planned for the PC, Mac and Xbox versions of L4D2
, so no one needs to feel left out. As an added bonus, the DLC will also contain three campaigns from Left 4 Dead 1
: Death Toll, Dead Air and Blood Harvest (L4D1's No Mercy campaign was included as part of L4D2's 'The Sacrifice
' DLC). Don't get too excited, however, as the DLC isn't planned to be released until after the release of Portal 2, which currently is slated for April
