Beta over here! L4D2 'Cold Stream' DLC now up for testing

Hey, remember when Valve announced that the new Cold Stream DLC for Left 4 Dead 2 would enter beta testing within the "next few weeks?" Guess what? It's been a few weeks! The DLC, created by modder Matthew Lourdelet, is now available for beta testing in both the PC and Mac versions of Left 4 Dead 2.

Valve warns that the campaign does have bugs -- it's a beta test, after all -- and asks players to report them via the in-game bug reporter. The company also invites feedback and suggestions -- particularly regarding the finale -- in the Cold Stream forums.
