In case it wasn't clear, this campaign is no longer maintained or supported in any way.

Campaign "details/7116" is an updated version ported in 2012/2013 by Keiji and/or Kevin (if my e-mail records serve me correctly), whose GameMaps account "profile/533937" for some reason currently bears my username but is not under my control. The port should contain all required HL2 content.

If you have any further issues, or like one reviewer wish to violate "[my] family members in eye and stupid mouth", please contact the author of the port.

============================================

Old description:

Lambda aims to bring the experiences from HL2 into L4D. IMPORTANT: Extraction of some HL2 files IS REQUIRED for functionality. READ THE CHANGELOG BEFORE DOWNLOADING! (The stacked files icon on the campaign screenshot) READ IT!
