Today we have released a pretty big update for Left 4 Dead 2 that includes map bug and exploits fixes. The complete list is here.

These changes will be coming to the Xbox 360 with the title update that will accompany Cold Stream’s release. Before we send the game off to certification, we want to test these fixes on the PC. So please, give these maps a play through and tell us what you think.

The Cold Stream DLC will include 21 maps in total - the Cold Stream, Blood Harvest, Crash Course, Dead Air, and Death Toll campaigns. Besides the massive amount of new content, 360 users will also be getting many of the bug fixes and changes we have implemented since the last update.

We don’t have a release date yet, but we will make sure to post the minute we do.
