Valve has released a few details on what the next downloadable content package for Left 4 Dead 2 will contain and when we can expect to see it.
The DLC, which has not yet been given an official name, will feature a new community campaign called 'Cold Stream' and is created by Matthew Lourdelet, who L4D vets may also recognise as the same person behind the popular '2 Evil Eyes' campaign.
The pack will also feature the three remaining Left 4 Dead 1 campaigns. Valve has also invited players check out a beta version of Cold Stream and submit feedback on it.
Though it didn't provide a specific release date, the company has said that it would be available "sometime after Portal 2".
Portal 2 writer Erik Wolpaw has said that the second, mind-bending Portal title was influenced by Left 4 Dead.
