Hop into the PC version of Left 4 Dead 2 today and you'll find a beta version of Left 4 Dead's Death Toll campaign ready to play. Valve is staying quiet about a few changes they've made to Death Toll so you'll just have to jump right in to see what's been tweaked.
Today's update also brings some modifications to the Cold Stream and Blood Harvest campaigns. The bridge area in Blood Harvest now has more room for Infected spawns while Cold Stream's finale received some changes. Valve is looking for feedback about Cold Stream's finale so drop a line with them here.
Now, you're all probably wondering about when the final version of the Cold Stream DLC will be released for PC and Xbox 360. At the current rate of testing, Valve is looking to have the whole thing ready by Halloween instead of summer as originally scheduled. The work has been long but it'll be worth the wait.
