You did it! You achieved the goal of playing a ton of Left 4 Dead 2
, in sufficient numbers to unlock more Left 4 Dead 2
. Valve challenged the community to get the "Stream Crosser" achievement 20,000 times by completing the Cold Stream campaign, and after 24 hours that achievement had been achieved 60,774 times.
As a result, Valve is releasing the L4D2
version of the L4D
"Dead Air" DLC early, as promised. The initial announcement said July 22 -- now Valve is saying July 22 at the latest
and intends to release the content as soon as it's finished.
