Valve have released their final original Left 4 Dead map on Left 4 Dead 2. The beta version of Death Toll has already been released and is looking like a classic already with new survivors and infected class. Death toll is going be an excellent addition to the Left 4 Dead 2 map pack and it is long over due in my eyes (but better late than never)

No official release date has been issued but it will when it has passed the BETA stages of testing.
