I had left at the end of February informing you of the will of Valve to bring other maps taken from the original game of Left 4 Dead 2 through the extra content called "Cold Stream". Since then there have been substantial developments, obviously reserved PC users: the development of the campaign that takes the name of the DLC, the arrival of the map "Dead Air" with some changes and finally the last entry of " Blood Harvest ", still in beta testing audience.

Valve, via its official blog last into the post, said that once completed this test defenses of the campaign "Blood Harvest", the three maps will be assembled in a single package for the Xbox 360 version, which, according to by the developers, the summer comes to an end.

However, it is likely that we will not see expansion in the marketplace until mid-September, given the reputation of the company to delay more than a few weeks of any additional content. We will keep you updated.
